Problems solved by technology

However, this technology uses plastic film as a binder. Although the rubber particles will be bonded together when melted at high temperature, the plastic film cannot penetrate around each rubber particle after heating, and the strength of the rubber floor mat is limited to a certain extent.

Abstract

The invention discloses a method of preparing an environment-friendly rubber floor mat by taking waste rubber and waste plastic as raw materials. The method effectively solves the problem of recyclingof waste rubber and waste plastic. According to the method, rubber particles and plastic particles are blended at a certain temperature, and the environment-friendly rubber floor mat is processed through the procedures of hot pressing, cold pressing and forming. The gaps of the rubber particles are filled with the plastic particles, the thermoplasticity of the plastic particles is utilized, the plastic is melted at high temperature, the rubber particles are firmly bonded together after being cooled, and the strength of the rubber floor mat can be greatly improved. In the crushing process of waste rubber and waste plastic, the particle size is strictly controlled, the situation that the strength of the floor mat is reduced due to too large particles is avoided, and the phenomenon that powder is discharged due to too small particles is further avoided. The problem of recycling of waste rubber and waste plastic is effectively solved, and no pollution is caused to the environment in the processing process.

Description

Technical field: [0001] The invention relates to a method for preparing floor mats from waste rubber and waste plastics. The waste rubber and waste plastics are crushed into granules, blended at a certain temperature, and processed into environmentally friendly rubber mats through hot pressing, cold pressing, and molding processes. pad. Background technique: [0002] As a ground decoration material, rubber floor mat has good anti-slip and good elasticity. Compared with concrete and marble and other ground decoration materials, it can avoid falling and bruising to a large extent, and is widely used in school plastic runways. The ground laying of recreational facilities, parks, gymnasiums, swimming pools, universities and company laboratories, etc. has been vigorously promoted in developed countries for decades, and is widely used as an excellent polymer environmental protection material to replace the existing cement floor. In my country recently It has just emerged in more th...
