Problems solved by technology

However, the degree of change in this situation is actually not great. One of the very important reasons is that there are few mature application technologies for waste rubber powder, resulting in a backlog of rubber powder products and poor sales.

Abstract

The invention discloses a scrap rubber powder / vegetable fiber composite foaming material and a preparation process thereof. The scrap rubber powder / vegetable fiber composite foaming material is prepared from the following components in part by weight: 80 to 120 parts of scrap rubber powder, 80 to 120 parts of vegetable fibers, 20 to 50 parts of high density polyethylene, 2 to 3 parts of benzoyl peroxide, 5 to 20 parts of maleic anhydride grafted polyethylene, 5 to 15 parts of azodicarbonamide, 10 to 30 parts of lubricating agent and 1 to 5 parts of heat stabilizer. The product can be granulated by dynamic extrusion and foamed by die pressing and has a simple preparation process, high cost performance and low cost. The scrap rubber powder / vegetable fiber composite foaming material can be used for manufacturing mute floors, floor tiles, buffer shockproof packaging materials such as inside linear, and the like.

Description

technical field [0001] The invention relates to a waste rubber powder / plant fiber composite foaming material and a preparation process thereof. Background technique [0002] In recent years, oil prices have soared, affecting the increase in synthetic rubber production; while natural rubber production has also stagnated. With the development of the automobile industry, my country has become the largest country in the world in terms of rubber consumption. About 45% of the annual rubber consumption needs to be imported, resulting in the soaring price of raw rubber. [0003] At the same time, waste rubber is increasingly polluting the environment. In 2007, more than 170 million tires were scrapped in my country. Nearly one million tons of waste rubber are not used rationally every year. This is mainly because the way of recycling waste rubber in my country is relatively simple, the recovery rate is very low, and the production of reclaimed rubber is mainly used, supplemented ...
