High-strength environmentally-friendly rubber powder rubber plate and preparation method thereof

Abstract

The invention provides a high-strength environmentally-friendly rubber plate prepared by directly utilizing waste rubber powder and a method for preparing the rubber plate. Components selected by theinvention and the proportion of the components ensure that the rubber plate has good mechanical properties. The tensile strength of the rubber plate is between 3.49 and 5.3, the elongation at break isbetween 94 and 150 percent, and the strength is 66 DEG. The method has the mainly characteristics of using the waste rubber powder to directly produce the rubber plate, and saving working proceduressuch as desulfurization and refining during the production of regenerated rubber. The method saves a large amount of special equipment, factory buildings, power and manpower, and can also save chemical raw materials such as a softening agent, a tackifier and the like; and in addition, no pollution of waste water, waste gas and flying dust generates in the technological process.

Description

technology field; [0001] The invention relates to rubber products and a preparation process, in particular to a rubber sheet prepared from waste rubber and a preparation method thereof. Background technique: [0002] At present, the main method for the utilization of waste rubber in my country is to make reclaimed rubber, that is, to completely remove the sulfur in waste rubber through crushing, desulfurization, pressing and other processes, so as to restore the elasticity and plasticity of rubber, thereby forming reclaimed rubber. . And use the reclaimed rubber as raw material to prepare new rubber products. This method has the disadvantages of large 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 different degrees of low-concentration organic waste gas in the waste rubber desulfurization regeneration process. air pollution. ...
