Abstract

The invention discloses an elastomeric product for modifying common soil and a production method thereof. The production method comprises the steps of: removing impurities in soil, drying, crushing and screening to obtain soil particles; then dynamically heating common soil particles, adding a surface modifying agent, drying to obtain modified soil, wherein the surface modifying agent comprises a coupling agent, polyorganosiloxane with reactive functional groups, organosilicon, fatty amine emulsifying bodies and water; and finally, preparing an elastic runway surface layer, a sports ground floor, synthetic leather, household and commercial floors, household and commercial wall decorating materials and the like by using the modified soil and crylic acid cementing agents as main components and doping with a compound prepared by a cross-linking agent, a softening agent, the coupling agent, a foaming agent or defoaming agent and the like. The product has no toxic and harmful gas volatilization in the whole production and use processes, has compression deformation ratio, rebound resilience and durability reaching or exceeding properties of rubber or some plastics, and is an elastic plane material with low cost, high performance and environment protection.

Description

technical field [0001] The invention relates to a polymer composite material and a production method thereof, in particular to a method for producing elastomer products by modifying ordinary soil. Background technique [0002] In the process of manufacturing plastics, rubber, paper, coatings, cables and other materials, adding fillers can save costs and improve the performance of materials. The coordination between them is a difficult problem in materials science. Soil is the cheapest kind of filler. Currently, non-metallic minerals are mainly used for fillers, such as kaolin, attapulgite, bentonite, china clay, coal gangue, etc. How to make the non-metallic mineral soil not affect or significantly improve the performance of the material after adding it is a hot research topic. There are many public literatures that introduce the modification of non-metallic minerals, and the excerpts are as follows: [0003] 1. [Title] Effects of Modified Calcined Kaolin on the Propertie...
