Abstract
The invention discloses a preparation method of rubber for a surface layer of a vacuum tire and belongs to the technical field of manufacturing of vehicle rubber accessories. The method comprises the steps that rosin is heated to be dissolved, then sodium hexametaphosphate, sodium pyrophosphate and sodium tripolyphosphate are added, and the mixture is stirred for 0.5 h to 1 h at the temperature of 85 DEG C to 95 DEG C; the prepared matter, nitrile rubber, carbon black, dilauryl thiodipropionate, zinc stearate and paraffin are put in an internal mixer for banburying at the temperature of 65 DEG C to 80 DEG C; the matter obtained after banburying is put in an open mill for extrusion forming firstly, then put in vulcanization equipment for vulcanization treatment, and lastly subjected to trimming, inspection, packaging and storage. The matter prepared from rosin, sodium hexametaphosphate, sodium pyrophosphate and sodium tripolyphosphate is mainly added to rubber for modification, and therefore the comprehensive performance of the product rubber is improved.
Description
Technical field
The invention belongs to automobile-used rubber accessory manufacturing technology field, particularly relate to the preparation method of a kind of vacuum tyre top layer rubber.
Background technology
The most tubeless pneumatic tire of vacuum tyre, also known as " low pressure tire " " air tyre ".The vacuum tyre use on bicycle, motorcycle, car, passenger vehicle, lorry in recent years is increasingly extensive.
Vacuum tyre has higher elasticity and wearability, and has good adhesive force and heat dispersion, and however as the continuous progress of science and technology, market is more and more higher to the requirement of each performance of vacuum tyre.
Summary of the invention
The technical problem to be solved is to provide the preparation method of the vacuum tyre top layer rubber of a kind of good combination property.
In order to solve above-mentioned technical problem, the technical solution adopted in the present invention is:
The raw material of its following weight portion of employing:
The double lauryl 20 parts～30 parts of nitrile rubber 100 parts, Colophonium 15 parts～20 parts, sodium hexameta phosphate 1 part～5 parts, sodium pyrophosphate 6 parts～10 parts, sodium tripolyphosphate 6 parts～10 parts, white carbon black 0.1 part～0.2 part, thio-2 acid, zinc stearate 15 parts～20 parts and 15 parts～20 parts of paraffin；
Comprise the following steps:
A, by above-mentioned raw materials proportioning, first rosin heating is melted, is subsequently adding sodium hexameta phosphate, sodium pyrophosphate and sodium tripolyphosphate, and stir 0.5 hour～1 hour at 85 DEG C～95 DEG C；
B, the material that nitrile rubber, white carbon black, the double lauryl of thio-2 acid, zinc stearate, paraffin and step A prepare is put into banbury, and banburying at 65 DEG C～80 DEG C；
C, first the material that step B banburying obtains to put into mill extruded, then places into and carries out vulcanizing treatment in vulcanizing equipment；
D, the material after step C vulcanizing treatment is carried out deburring, check, pack, put in storage.
Owing to using technique scheme, there is advantages that
The present invention mainly carries out changing surname by adding the material prepared by Colophonium, sodium hexameta phosphate, sodium pyrophosphate and sodium tripolyphosphate in rubber, thus improves the combination property of product rubber.
