Abstract

The invention discloses a preparation process of molded rubber composite plate, which comprises the following steps: evenly mixing 100 parts of reclaimed rubber, 10-20 parts of vulcanizing agent, 0.3-5 parts of vulcanization accelerator, 0.1-10 parts of activator, 0.1-80 parts of bulking agent, 0.1-1.5 parts of anti-aging agent and 0.1-5 parts of plasticizing agent on a double-roll mixer to prepare hard mixing rubber, evenly mixing 60-80 parts of natural rubber, 20-40 parts of EPT rubber, 1-5 parts of vulcanizing agent, 0.5-5 parts of vulcanization accelerator, 1-10 parts of activator, 1-80 parts of bulking agent, 1-6 parts of anti-aging agent, 1-6 parts of plasticizing agent and appropriate amount of coloring agent on the double-roll mixer to prepare soft mixing rubber, coating soft mixing rubber on the surface of the hard mixing rubber, conducting the co-cure under the conditions of heating and pressurizing to prepare rubber composite plate. The molding rubber composite plate which is prepared by the process of the invention has the characteristics of high elasticity and antiskid, creep deformation resistance, light weight and moisture proof, abrasion resistant, anti-aging, convenient washing and nourishing and strong decorativeness and the like.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a molded rubber composite plate and a preparation method thereof. Background technique [0002] Since the 1990s, on the one hand, with the increasing awareness of environmental protection in all countries in the world, the cutting of forests has been restricted; on the other hand, with the improvement of people's living standards, the demand for wood has increased greatly. Therefore, finding new wood substitutes and creating a "second forest" has become an urgent problem to be solved. [0003] Modern society produces a large amount of waste rubber products, such as waste tires, every day. According to statistics, there are currently 1.5 billion tires scrapped every year in the world, and its recycling and utilization are conducive to environmental protection and resource reuse. [0004] Based on the above background, people are actively looking for a new substitute for wood-rub...
