Embodiment 1
[0032] A green antibacterial carbon fiber reinforced PVC material, the ratio of each raw material is as follows:
[0033]
[0034] The modified kaolin is prepared by the following method: calcining the kaolin at 400°C for 2 hours, cooling to room temperature, soaking in a sulfuric acid solution with a mass concentration of 10% for 3 hours, filtering, washing until neutral, drying, and pulverizing , through a 300-mesh sieve; the sieved powder is stirred with water to make a suspension with a concentration of 40%, and then 1% of the weight of the suspension is added with sodium tripolyphosphate, 2% of water-soluble nano-scale silica sol, and 2% of molybdenum Sodium phosphate, 2000rpm high-speed shear dispersion for 15 minutes, spray drying.
[0035] The modified barium sulfate is composed of the following components: 50 parts of barium sulfate, 0.5 part of coupling agent and 0.6 part of stearic acid.
[0036] The composite auxiliary agent is prepared by the following method:...
