Manufacturing Process Of Terpene Resin

Terpene resin, also named polyterpene resin or pinene resin. It is a series of liquid & solid linear polymer which primarily consist of α pinene or β pinene of turpentine that are catalyzed by Falk's catalytic, and polymerized by positive ion.

Manufacturing Process Of Terpene Resin: Add the α-pinene component, β-pinene component monomer, chemical agent and the catalyst to a three-necked flask equipped with a stirring counter and a thermometer. After the reaction time set at the predetermined reaction temperature, The addition of hot water destroys the chemical catalyst to prevent the polymerization from occurring and, at the same time, heating the homogeneous agitation. When the system reaction temperature rose to 85 ℃ when the suspension to continue heating, leaching of solid residue precipitation, and the static filtrate placed automatic chromatography. The organic phase compound was separated using a liquid separatory funnel and washed with boiling water to pH-neutral. Neutral organic compounds are isolated under normal pressure, chemical reagents and a small amount of unpolymerized chemical synthesis of turpentine, and then reduce the pressure in the case of lower boiling point homopolymer, the fraction of the residue that is able to get this Terpene products.

About Resin Chemical

Resin is usually refers to the softening or melting range after the heat, softening under the action of external forces tend to flow, at room temperature is solid, semi-solid, and sometimes can be liquid organic polymer. Broadly speaking, any polymer that can be processed as a raw material for plastic products is called a resin. Resin has a natural resin and synthetic resin of the points. Natural resin refers to the nature of animal and plant secretions from the amorphous organic matter, such as rosin, amber, shellac and so on. Synthetic resin refers to the simple organic compounds by chemical synthesis or certain natural products obtained by the chemical reaction of the resin products. High-speed mixed bed resin; moving bed and cover the filter with resin and other categories.

Application Of Ester Of Rosin In Tackifier For Adhesive

The tackifier resins include hydrocarbon resins, rosin and rosin derivatives, and terpene resins. The choice of tackifier resin depends on its end use, cost and performance. Quality indicators include color and color stability, oxidation stability, odor, softening point, acid value and compatibility in the formulation of adhesives. At present, much ester of rosin produced in the United States are available in 3-4 Gardner colors. In order to improve the stability of the color, hydrogenation is usually used.

The disproportionation method removes the conjugated unsaturated moiety, and the antioxidant can also be used to improve color stability. Some adhesives require components of an odorless ester of rosin as tackifier for adhesive. Usually steam is sprayed under vacuum, and the other is the odor of the masking agent. In a constant tackifier / polymer ratio, increasing the softening point in the tackifier causes the pressure-sensitive adhesive to become more viscous and its cohesive strength to decrease. In contrast, increasing the softening point in the tackifier reduces the tack and increases the cohesive strength. The acid value of the commercial rosin ester tackifier is usually between 5 and 15.

The Manufacturing Process Of Terpene Resin

Terpene resin, also known as terpene or pinene resin. It is mainly the use of turpentine a-pinene or β-pinene, in the Fock's catalyst under the action of cationic polymerization from the liquid to the solid of a series of linear polymer.

 

The α-pinene component, the β-pinene component mixed monomer, the chemical agent and the catalyst are added to a three-necked flask equipped with a stirrer and a temperature measuring device in a predetermined order, and then the mixture is discharged for a period of time according to the set temperature Into the boiling water to destroy the catalyst to stop the copolymerization of chemical reactions, while heating uniform mixing. When the reaction temperature of the system reached 85 ° C, the temperature was not increased, the residue was separated by filtration, and the filtered solution was allowed to stand for stratification. The organic phase material was diafiltered with a stratified segregation funnel and washed with boiling water to a neutral pH. Acid-base neutral organic compounds filter out chemical reagents and a small amount of turpentine which does not undergo polymerization at atmospheric pressure, and then filter out the lower boiling polymer mass under reduced pressure conditions, and the fraction remains to obtain this Terpene Resin.

About Ester Of Rosin

Ester Of Rosin is type of polyol ester of abietic acid. The polyol ester are commonly glycerol and pentaerythritol. Polyol Rosin ester is a light yellow transparent solid, softening point in the 90 ~ 110 ℃, acid value of 10 to 20. For paint, rosin soap made by the quality of the system were slightly higher. The softening point of pentaerythritol rosin ester is higher than that of glycerol ester of rosin, and the drying performance, hardness and water resistance of varnish is better than that of glycerol rosin ester. Such as the use of polymerized rosin or hydrogenated rosin as the raw material made of the corresponding ester, reducing the tendency to change color, other properties have improved. The softening point of the polymerized rosin ester is higher than that of the rosin ester and the softening point of the hydrogenated rosin ester is lowered.

Terpene Phenolic Resin In Water Based Tackifier Resin

Water Based Tackifier Resin is a polymer synthesized by Terpene Phenolic Resin, a gelling agent for transparent systems and a thickener for oil-in-water emulsions. The polymer has been neutralized in advance and is convenient to use, giving excellent formulation performance, even in the absence of emulsifiers. Products containing this material, the appearance looks very thin, but with a certain viscosity. In addition to these advantages, but also has the rheology, pleasant skin feeling, low viscosity sticky and so on. Because it is evolved from sulfuric acid, so at low pH can also be made into oil-in-water emulsion, and easy to match with the acid.

This material with organic solvents such as ethanol, acetone good match, in the ultraviolet light irradiation or high shear force is still very stable. Water Based Tackifier Resin is added in personal care products in the amount of 0.5-1.2%.

How To Use Water Based Emulsion In Adhesive Tape Manufacturing

The clear gel was prepared by adding water to the Water Based Emulsion, which had to be handled with care.

The clarity of the final clearcoat depends on the amount of Water Based Emulsion added to the formulation. More than 1% of the amount of the opacity imparted to the product is transparent. The slightly cloudy gel can be made transparent by the addition of a 5% solvent such as glycerol, preferably treated Deionized water containing metal ions.

Water Based Emulsion is compatible with other polar organic solvents. The clear gel may even contain more than 50% ethanol. Typically, a water / alcohol mixture is added to the it. Ethanol can be used to solubilize active additives Avoid the use of BF-225 like hydrogenated castor oil. In this way, transparent oils containing essential oils, oil-soluble UV sunscreens, active additives, film-forming agents can be readily prepared. In the case of high ethanol content the traditional preservatives are not suitable.
