Preparation method for rubber ground mat

Abstract

The invention discloses a preparation method for a rubber ground mat, and relates to the technical field of daily living goods. The method concretely comprises the following steps: (1) manufacturing abottom layer; (2) manufacturing a surface layer; (3) firstly putting the bottom layer into a molding mould, coating the surface of the bottom layer with a polyurethane foamed layer, then putting thesurface layer on the polyurethane foamed layer, and performing pressing molding through the molding mould; and (4) performing hot pressing molding treatment on the back surface of a molded ground matobtained in the step 3, so as to enable the back surface of the ground mat to form a rough surface with certain patterns. According to the invention, through structures of the bottom surface and the surface layer, shock damping performance is guaranteed, and at the same time abrasion resistance and pressure resistance are increased.

Description

technical field [0001] The invention relates to the technical field of daily necessities, in particular to a method for preparing a rubber floor mat. Background technique [0002] The elastic safety floor mat has perfect impact absorption performance, and is mainly suitable for children's amusement parks, kindergartens, sports equipment areas for primary and secondary schools, park passages, pedestrian bridges, shooting ranges, gyms, nursing homes, national fitness path areas, gymnasiums, etc. It can effectively protect users from injuries caused by falling from a high place. The application process requires the product to have high physical properties, environmental protection, easy cleaning and good drainage; it is suitable for laying on indoor and outdoor amusement and fitness grounds to protect children's safety. [0003] The raw materials of existing rubber safety mats are mainly waste rubber granules, waste rubber and plastic granules or EPDM granules, etc. At present,...

AI Technical Summary

Problems solved by technology

[0003] The raw materials of existing rubber safety mats are mainly waste rubber granules, waste rubber and plastic granules or EPDM granules, etc. At present, the production of such granule raw materials is mostly broken and waste rubber or rubber and plastic products, such as sneaker soles, tires, rubber hoses, cables Leather, etc., the heavy metal content in this kind of granular raw materials is high, and in the case of outdoor rainwater infiltration, it is easy to cause heavy metal enrichment in the soil at the bottom of the mat, polluting the environment

At the same time, the glue used to bond the particles is an organic compound, good and bad, poor quality glue may contain highly toxic chemicals TDI and organic solvents, such as toluene, xylene, etc., and the organic solvents that may be added during the production process will further increase pollution. Possibility of the environment; after one year of use, the product is prone to shrinkage, deformation, edge warping and surface wear. It is easy to trip the user during use, causing safety accidents. The sludge deposited in the gaps on the surface of the product is not easy to clean, etc.
