Embodiment Construction

[0013] The present invention proposes a kind of highly dispersible resorcinol-80 synthetic preparation method, it comprises the following steps:

[0014] Step 1: Prepare raw materials including resorcinol, styrene-butadiene rubber (SBR1502), EPDM rubber (EPDM4640), softening oil, zinc stearate, polyethylene wax, and prepare carrier rubber and dispersant;

[0015] The equipment used to prepare the carrier rubber and dispersant includes a rubber cutting machine, a precision electronic scale (accurate to 0.5 grams), and a drug storage tank (or storage car).

[0016] The specific operation process is: according to the formula of the product, remove the inner mold of the carrier rubber. The dispersant is accurately weighed, and then the first-hand dispersant is mixed and put into the storage tank (storage car), and put into the computer conveyor together with the prepared carrier rubber, and transported to the next step.

[0017] Step 2: Mixing with internal mixer (Lina machine); ...

Abstract

The invention relates to a synthesis and preparation method of high dispersibility resorcinol-80, which comprises the following steps of: 1, preparing for raw materials comprising resorcinol, butadiene-styrene rubber (SBR1502), ethylene-propylene diene monomer (EPDM4640), flux oil, zinc stearate and tissuemat E and preparing the carrier rubber and the dispersant; 2, mixing by using an internal mixer (Lina Machine); 3, extrusion molding for pelleting; 4, carrying out surface treatment on particles of the product; 5, initially cooling and screening the particles; 6, finally cooling the particles; and 7, detecting and packaging the particles of the product. The high dispersibility resorcinol-80 synthesized and prepared in the invention is prepared by adding special rubber and dispersant after subjected to special treatment of high purity resorcinol. The high dispersibility resorcinol-80 is added at lower temperature during mixing and can be dispersed in the rubber material uniformly; and the special rubber and the dispersant selected are beneficial to improving the bonding intensity of the mixed rubber, and solves the problems that the pure crystal of resorcinol during mixing generates toxic smoke due to sublimation, is not easy to disperse and easy to absorb moisture and the like.

Description

technical field [0001] The invention relates to a method for synthesizing and preparing resorcinol-80, in particular to a method for synthesizing and preparing resorcinol-80 with high dispersibility. technical background [0002] Traditional resorcinol has poor dispersibility, and it is difficult to improve the adhesive strength of the mixed rubber. Therefore, pure crystals of resorcinol produce toxic fumes due to sublimation during mixing, and are difficult to disperse and easy to absorb moisture. Therefore, if a resorcinol-80 with high dispersibility can be synthesized, it will bring very large economic and environmental benefits. Contents of the invention [0003] The technical problem to be solved by the present invention is: to overcome the traditional poor resorcinol dispersibility, resulting in the production of toxic smoke, easy to absorb moisture, and to provide a synthetic preparation method of highly dispersible resorcinol-80, which has huge economic and enviro...
