▎ 摘  要

NOVELTY - Mildew-proof and antibacterial silicone rubber fabric comprises 60-70 pts. wt. methyl vinyl silicone rubber, 4-6 pts. wt. silver-loaded nano-titanium dioxide, 10-20 pts. wt. bamboo carbon powder, 4-8 pts. wt. copper pyrithione, 0.2-0.4 pts. wt. sodium hexametaphosphate, 0.6-1 pts. wt. butyl p-hydroxybenzoate, and 3-5 pts. wt. vulcanizing agent. USE - The mildew-proof and antibacterial silicone rubber fabric is useful in the fields of automobiles, medical care, construction, and daily necessities. ADVANTAGE - The fabric has high antibacterial effect, and has good mildew-proof performance. The inhibition rate of Escherichia coliand Staphylococcus aureusof the fabric is 99.9% (preferably 99.99%) and 98.35% of the bacteriostasis rate of respectively Escherichia coliand Staphylococcus aureus, has high heat aging resistance and high temperature compression resistance. The bamboo carbon powder has large specific surface area and strong adsorbability, which can absorb water in the fabric keeping the inner dry to make the fabric mildew-proof effect. The butyl p-hydroxybenzoate improves the dispersibility of silver-loaded nano titanium dioxide. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for producing the mildew-proof and antibacterial silicone rubber fabric, comprising adding raw materials to the silicone rubber, uniformly mixing the mixture to obtain a mixture A, coating the mixture A on the release paper and bonding it with the flame retardant bass, vulcanizing at 100-140°C for 5-10 minutes, peeling off the release paper, and obtaining silicone rubber fabric.
