Description
Technical field
The invention belongs to technical field of fine, more particularly to a kind of rubber homogenizing agent and preparation method thereof.
Background technology
Rubber molecule it is bulky, elongated strand is easily tangled, and causes viscosity big, though at processing temperatures,
Mobility is still very poor, hinders uniform mixing.Rubber homogenizing agent belongs to new type rubber processing aid, its major function be exactly solution never
Uneven with the mixing because caused by viscosity is different of glue kind, in addition, homogenizing agent also has plasticising, thickening and lubricating function,
Processability, the reduction energy consumption of blended rubber can be improved, the air-tightness of tire flap layer sizing can be especially effectively improved.
Rubber homogenizing agent takes the lead in being developed and applying in western developed country and area, current major producing country be Germany,
The developed countries and regions such as the U.S. and Japan.The homogenizing agent of German S＆S companies production takes the lead in coal tar asphalt and petroleum extn
After the aliphatic saturated hydrocarbons such as thing and aromatic hydrocarbon monomer heating, polymerization, then prepare after the process steps such as solvent extraction；Also have one
Determining polymer such as anime, cycloparaffin resin or aliphatic hydrocarbon resin, Erbium-doped lumps together in specific proportions, then is obtained through granulation.Import
Homogenizing agent function admirable, but price is significantly larger than home products and seriously restricts the competitiveness of China's Rubber Industry in the world.
Domestic Ye You many enterprises and colleges and universities are studied homogenizing agent, but quality still suffers from no small gap with imported product.
The content of the invention
The purpose of the present invention is to prepare one kind to substitute import, with low cost, simple production process, the rubber that raw material is easy to get
Glue homogenizing agent and preparation method thereof.
Specific technical scheme is as follows：A kind of rubber homogenizing agent, raw material includes by weight ratio：Modified petroleum resin 40 ~
65 parts, 35 ~ 60 parts of aromatic acid zinc salt.
A kind of preparation method of rubber homogenizing agent, is comprised the following steps that：Petropols and initiator mixing, are heated to
90 ~ 150 DEG C, acrylate is slowly added to, 2 ~ 5h of polymerisation in bulk obtains modified petroleum resin, aromatic acid zinc salt is added by weight ratio
Mixing cladding, melt pelletization produces final products.
The Petropols are C5 Petropols（Aliphatic hydrocarbon resin）, C5/C9 Petropols（Aliphatic hydrocarbon, aromatic hydrocarbon tree
Fat）, C9 Petropols（Aromatic hydrocarbon resin）In one kind.
The initiator is dibenzoyl peroxide (BPO) or azodiisobutyronitrile（ALBN）In one kind, addition is
The 0.05% ~ 0.2% of Petropols quality.
The acrylate is methyl acrylate, ethyl acrylate, 2- methyl methacrylates or 2- methacrylic acid second
One or more in ester.
The mass ratio of the Petropols and acrylate is 1:1~1:0.1.
The aromatic acid zinc salt is one in zinc benzoate, terephthalic acid (TPA) zinc, zinc phthalate, M-phthalic acid zinc
Plant or a variety of.
The rubber homogenizing agent that the present invention is provided is according to the similar principle that mixes, ester group, phenyl ring, the fat of opposed polarity in molecule
Straight chain moistens the micelle surface of opposed polarity, reduces the surface tension of micelle, improves glue and mixes uniformity, while promoting rubber
Disperseing for middle inorganic filler, can obviously improve the mobility of sizing material, improve the dispersiveness of carbon black；The wearability of vulcanizate is improved,
And other physical properties of vulcanizate are influenceed without big.This product production cost is relatively low, and technique is simple, alternative imported product.
