Embodiment 1

[0012] Put 66kg of SBR with a butadiene content of 75%, 17kg of SIS, 6.5kg of naphthenic oil, 8kg of pottery clay, and 0.9kg of monoglyceride stearate into a pressurized internal mixer in sequence, and control the temperature of the internal mixer to 118°C , banburying and plasticizing for 8min; adding 0.5kg of benzimidazole-2-methoxymethyl carbamate with a purity of 98.0% and 0.4kg of silver-loaded zirconium phosphate with a silver content of 3.3% to mix the antimicrobial agent 0.9kg and purity 0.5kg of 98.5% tributyltin acetate and 0.3kg of pentachlorophenol with a purity of 99.0% are mixed with 0.8kg of antifungal agent, and banburying is continued for 5min; then add OBSH 1.8kg, sodium n-butylsulfonate 0.75kg, DCP 0.75kg, then banburying for 3 minutes; put it into a double-roll rubber mixer for mixing, control the temperature of the rollers at 100°C, and after double-roll mixing for 6 minutes, pull out a sheet with a thickness of 1.3mm; place it in the first In the molding ...

Embodiment 2

[0014] Put 64kg of SBR with a butadiene content of 75%, 15kg of SIS, 6kg of naphthenic oil, 7kg of pottery clay, and 0.7kg of monoglyceride stearate into a pressurized internal mixer in sequence, and control the temperature of the internal mixer to 116°C. Mixing and plasticizing for 8min; adding 0.4kg of benzimidazole-2-methoxymethyl carbamate with a purity of 98.0% and 0.3kg of silver-loaded zirconium phosphate with a silver content of 3.3% to form antimicrobial agent 0.7kg and a purity of 0.6kg of antifungal agent mixed with 0.4kg of 98.5% tributyltin acetate and 0.2kg of pentachlorophenol with a purity of 99.0%, and continue banburying for 5min; then add OBSH 1.6kg, sodium n-butylsulfonate 0.6kg, DCP 0.7kg, and banbury for 3 minutes; put it into a double-roll rubber mixer for mixing, control the temperature of the rollers at 98°C, and after two-roll mixing for 6 minutes, pull out a sheet with a thickness of 1.3mm; place it in the first mold press In the foaming machine, con...

Embodiment 3

[0016] Put 68kg of SBR, 19kg of SIS, 7kg of naphthenic oil, 9kg of pottery clay, and 1kg of monoglyceride stearate with a butadiene content of 75% into a pressurized internal mixer in sequence, and control the temperature of the internal mixer to 120°C. Refining and plasticizing for 8 minutes; adding 0.6 kg of benzimidazole-2-methoxymethyl carbamate with a purity of 98.0% and 0.4 kg of silver-loaded zirconium phosphate with a silver content of 3.3% to form an antibacterial agent 1.0 kg and a purity of 98.5 0.6kg of tributyltin acetate and 0.3kg of pentachlorophenol with a purity of 99.0% are mixed with 0.9kg of antifungal agent, and banburying is continued for 5min; then add OBSH 2.0kg, sodium n-butylsulfonate 0.9kg, DCP 0.8 kg, and then banbury for 3 minutes; put it into a double-roller rubber mixer for mixing, control the temperature of the rollers at 102°C, and after double-roller mixing for 6 minutes, pull out a sheet with a thickness of 1.3mm; place it in the first molding...

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...
