Abstract

The present invention relates to a preparation method of antibacterial and antifungal, styrene-butadiene-rubber, foamed sheet. Using 62-70 % SBR as basic material, 14-20% SIS, 0.6-1.2% antibacterial agent, 0.5-1.0% antifungal agent, 5-8% naphthenic oil, 6-10% clay, 1.4-2.2% OBSH, 0.5-1.0% sodium butyl dithiocarbonate, 0.5-1.0% DCP, and 0.6-1.2% glyceryl monostearate are added, after passing through plasticization, twin-roll mixing, first moulding foaming, cooling, second moulding foaming, cooling pitching, and punching shear, the production is formed. The foamed sheet prepared by this method, has low density, high impact resistance, good compression reducibility, wear resistance and slip resistance, good damping effect, no poison and no smell, especially, has excellent antibacterial and antifungal ability, is suitable for the floor board of indoor fitness and exercise sites, and can effectively inhibit pathogenic bacteria and mildew's reproduction and living, thus improves the sanitarian condition of the fitness and exercise sites.

Description

technical field [0001] The invention relates to a method for preparing a rubber foamed board, in particular to a method for preparing an antibacterial and mildew-proof styrene-butadiene rubber foamed board. Background technique [0002] With the sustained and rapid development of the national economy and the improvement of people's living standards, fitness exercises have increasingly become a fashionable way for urban residents to keep fit and cultivate their sentiments in their spare time. In recent years, a variety of indoor fitness sports, such as dance, gymnastics, Sanda, body training, etc., have become very popular. Gym floor mat materials have emerged as the times require and have developed rapidly. PVC foam boards, EVA foam boards, SBS / LDPE rubber and plastic foam sheet, NBR / PVC rubber and plastic sheet, TPU high elastic sheet, etc. These boards have the characteristics of soft texture, good resilience, non-slip and wear resistance, etc., and have good cushioning p...
