Abstract

The present invention discloses high strength environment friendly rubber plate and its making process. The material for the rubber plate includes waste rubber powder 80-120 weight portions, vulcanizing accelerator 0.5-0.8 weight portion, vulcanizing activator 0.5-0.8 weight portion, and sulfur 1.5-1.7 weight portions. The making process of the rubber plate includes the following steps: weighing the material components; drying the waste rubber powder; mixing all the material and molding; and vulcanizing at temperature of 120 -160 deg.c and pressure of 3.4-4.5 kgf / sq cm for 10-20 min. The rubber plate has excellent mechanical performance and may be used in making different rubber products. The present invention has the advantages of simple making process, saving in chemical material and no environmental pollution.

Description

technical field [0001] The invention relates to rubber products and a preparation process thereof, in particular to a rubber sheet prepared from waste rubber and a preparation method thereof. Background technique [0002] At present, the main method of waste rubber utilization in my country is to make reclaimed rubber, that is, to completely remove the sulfur in waste rubber through crushing, desulfurization, rolling and other processes, so as to restore the elasticity and plasticity that rubber should have, thus forming recycled rubber. glue. And use the reclaimed rubber as raw material to prepare new rubber products. This method has the disadvantages of high production energy consumption, low production efficiency and long production process, and in view of the current technical and economic conditions, many reclaimed rubber companies in my country have low-concentration organic waste gas in the process of desulfurization and regeneration of waste rubber. (sulfur-containin...
