Abstract

The invention relates to a rubber diatom ooze floor mat and a preparation method thereof. The rubber diatom ooze floor mat comprises a bottom layer, a middle layer and a surface layer which are arranged in a layered mode from bottom to top. The bottom layer is prepared from the following raw materials in parts by weight: 35-45 parts of natural rubber, 7-11 parts of diatomite, 50-60 parts of calcium carbonate, 2-4 parts of white oil and 1-3 parts of resin; the middle layer comprises the following raw materials in parts by weight: 2.5-4.5 parts of polyester fibers; and the surface layer comprises the following raw materials in parts by weight: 2.5-4.5 parts of polyester fibers. According to the rubber diatom ooze floor mat, after detection, the tearing strength, the hardness, the tensile strength, the elongation at break and the rebound rate all reach high levels, the toughness, the elasticity and the strength of the material are enhanced after all the components are reasonably matched, and the multiple problems that traditional diatom ooze is fragile, rough, stiff and the like can be effectively solved; and the preparation method is simple and easy to control, and large-scale production is facilitated.

Description

technical field [0001] The invention belongs to the field of household products, and in particular relates to a rubber diatom mud floor mat and a preparation method thereof. Background technique [0002] Diatom mud mats are made from diatomaceous earth. Diatomaceous earth is a natural mineral, its main component is silicic acid, and has a special microporous structure. When the indoor humidity rises, the ultra-fine pores can automatically absorb moisture in the air. Therefore, the floor mat made of diatomaceous earth has relatively strong water absorption, so it is often used in bathrooms to absorb moisture from the soles of people's feet after bathing, and it is safe and non-slip, which is extremely convenient. [0003] However, after long-term use, the cracking and breaking of the diatomite material tends to be aggravated. In the final analysis, the mechanical properties of the material still cannot meet the requirements. [0004] Therefore based on this, propose technic...
