Abstract
The present invention relates to composite hydrocarbon tackifying resin for rubber industry and a preparation method thereof, which belongs to the technical field of chemical industry, and a C9 polymer rich in styrene-indene distillation fractions is used as a main component of the composite hydrocarbon tackifying resin. C9 aromatics rich in styrene-indene distillation fractions are polymerized under the action of a catalyst at the temperature of 60 to 70DEG C to obtain a polymer by controlling the conversion rate and removing the catalyst; the polymer, xylene resin, rosin, octyl phenol resin and C5 resin are proportionally mixed, heated and stirred; unpolymerized aromatic monomers are removed by distillation to obtain the composite hydrocarbon tackifying resin. The product of the present invention performs the action of softening and tackifying in rubber and has particularly obvious effects on a formula having a high dosage of synthetic rubber.
Description
The present invention relates to a kind of with C
9Rich in styrene-indenes fraction polymkeric substance is the hydrocarbon composite viscosity increasing resinf or rubber industry and the preparation method of major ingredient, belongs to chemical technology field.
Tackifier and tenderizer commonly used when the Bias tyre in the rubber industry prepares are coumarones, the large percentage of natural gum during this tackifier require to fill a prescription in use, and the synthetical glue ratio is less, prepared tire cost height.Tackifier commonly used at present also have C
5Resin uses C
5Resin can improve the ratio of synthetical glue in the prescription, but tackify effect and calendering process all have certain defective, and the aging rate of sizing material, tensile yield and tearing force are desirable not enough.CN1101650A discloses a kind of manufacture method of vinylbenzene-indene resin, uses C
9Rich in styrene-indenes fraction is that raw material is made vinylbenzene-indene resin under catalyzer, chain terminator effect.Here the full content of this application is drawn and be reference.
The objective of the invention is to remedy the deficiency of prior art, provide a kind of and can improve the sizing material physicals, improve the compound tackifying resin of hydro carbons and the preparation method of processing characteristics.
The objective of the invention is to be achieved through the following technical solutions.
The raw material of the compound tackifying resin of hydro carbons of the present invention is:

Preparation method of the present invention comprises the steps:
A.C
9Aromatic hydrocarbons rich in styrene-indenes fraction is under the effect of the catalyzer of 1-2%, and 60-70 ℃ kept 4 hours, control yield 45-55%, and denitrating catalyst gets polymeric liquid;
B. with above-mentioned C
9Aromatic polymer and 4.5-9.5% xylene resin, 4.5-9.5% rosin, 4.5-9% octyl phenol resin, 4.5%C
5Resin is mixed in proportion, and 120-140 ℃ of temperature stirred 4 hours; Unpolymerized aromatic monomer is removed in 120-200 ℃ of distillation, reflux, and 85-95 ℃ of control softening temperature gets the compound tackifying resin of hydro carbons.
Above-mentioned catalyzer is aluminum chloride (solid or liquid) catalyzer or boron trifluoride (liquid or gas) catalyzer.
The compound tackifying resin of hydro carbons of the present invention had both played ramollescence in rubber, can play viscosifying action again, particularly remarkable for synthetical glue consumption height, prescription effect that loading level is big, help the dispersion in rubber of carbon black, other weighting agents, improve its degree of scatter.When mixing, can reduce the viscosity of rubber unvulcanizate temperature and sizing material, improve calendering process, can improve the half-finished autohension of sizing material simultaneously and endure property, improve the process industrial art performance of operation down.When sulfuration, can increase the reactive force between rubber molecule, improve the intensity and the elasticity of rubber item, play certain strengthening action.
