Embodiment 1

[0037] A kind of odorless rubber material is prepared through the following steps:

[0038] Step 1: Take standard rubber, solution-polymerized styrene-butadiene rubber and butyl rubber powder according to the data corresponding to Example 1 in Table 1, and mix them at room temperature to make styrene-butadiene rubber. Put the initiator for graft polymerization of styrene-butadiene rubber into the internal mixer and directly add it into the rubber emulsion, obtain modified styrene-butadiene rubber under the conditions of 135°C, rotor speed 40r / min and reaction time 3min, and modify the styrene-butadiene rubber Rubber made into powder;

[0039] Step 2: According to the data corresponding to Example 1 in Table 1, the other raw materials except step 1 were weighed, and then mixed with modified styrene-butadiene rubber;

[0040] Step 3: After uniform mixing, six basic processes of mastication, kneading, calendering, extrusion, molding and vulcanization are carried out at 120° C. t...

Embodiment 2

[0042] Each raw material was weighed according to the data corresponding to Example 2 in Table 1. Adopt the method described in embodiment 1 to prepare odorless rubber material.

Embodiment 3

[0044] Each raw material was weighed according to the data corresponding to Example 3 in Table 1. Adopt the method described in embodiment 1 to prepare odorless rubber material.

Abstract

The invention discloses an odorless rubber material. The odorless rubber material is prepared from components in parts by weight as follows: 50-70 parts of modified SBR (styrene-butadiene rubber), 20-40 parts of PVC (polyvinyl chloride), 7-13 parts of N330 carbon black, 40-60 parts of white smoke, 20-30 parts of calcium carbonate, 15-25 parts of rubber raw oil and 5-10 parts of a vulcanizing agent. A preparation method of the odorless rubber material comprises the following steps: step 1, SBR is prepared from 15-25 parts of standard rubber, 50-70 parts of solution polymerized SBR and 100 parts of butyl rubber powder weighed by weight, and then 5-10 parts of maleic anhydride, SBR and an initiator are fed into an internal mixer and directly added to rubber emulsion; step 2, 20-40 parts of PVC, 7-13 parts of N330 carbon black, 40-60 parts of the white smoke, 20-30 parts of calcium carbonate, 15-25 parts of the rubber raw oil and 5-10 parts of the vulcanizing agent are weighed by weight and all mixed with modified SBR; step 3, six basic procedures including plastication, mixing, calendering, extrusion, forming and vulcanization are performed at 120 DEG C, and the odorless rubber material is obtained. The odorless rubber material has the advantage that no odor is emitted in a use process.

Description

technical field [0001] The invention relates to rubber materials, in particular to a method for making odorless rubber materials. Background technique [0002] At present, general rubber products have peculiar smell no matter they are natural rubber products or artificial rubber products. For example: car floor mats, sealing rings, gaskets, backing plates, etc., all have the problem of large rubber smell. If it is in a closed space, the rubber smell will be greater. This rubber smell not only makes people feel very uncomfortable after inhaling it, but also has a bad effect on people's health. Rubber is a kind of product that is harmful to environmental protection construction and not conducive to human health, but it is inseparable from people's production and life, especially in industry. People are badly in need of a healthy and environmentally friendly rubber product supply market without rubber smell. [0003] The Chinese patent with the publication number CN104045879...
