Problems solved by technology

[0002] As a widely used material, plastic is applied to people's daily life and all walks of life. Due to the addition of plasticizers, it is flammable and melts at a slightly higher temperature, thus greatly reducing the use of plastics. Safety, and with the development of society and the improvement of people's safety awareness, people's requirements for plastic products are getting higher and higher. Therefore, in order to meet people's requirements, the existing plastic products have various functions, such as Waterproof and flame retardant plastics, anti-aging flame retardant plastics, acid and alkali resistant plastics, antibacterial plastics, etc., to meet different market demands, but the existing antibacterial plastics have poor antibacterial effect and cannot achieve the purpose of real antibacterial and anticorrosion

Embodiment 1

[0015] An anti-corrosion and flame-retardant plastic, which consists of the following components by weight: 95 parts of ABS, 85 parts of PC, 12 parts of mica powder, 10 parts of quartz sand, 25 parts of flame retardant, 11 parts of carbon black, 12 parts of soybean oil, 10 parts of corn flour, 5 parts of antibacterial preservative. Among them, the flame retardant is composed of antimony trioxide, dimethyl trimethylsilyl phosphonate, chlorinated paraffin and molybdenum trioxide in a weight ratio of 3:2:1.5:1.5, and the antibacterial antiseptic is composed of silver zeolite , chitosan, and pomegranate peel extract are mixed in a weight ratio of 4:1.5:1.5.

[0016] The products prepared in this example were tested by industry standard experiments, and the results were as follows: the 24-hour sterilization rate of Escherichia coli reached 99.4%, and the 24-hour sterilization rate of Staphylococcus aureus reached 99.8%.

Embodiment 2

[0018] An anti-corrosion and flame-retardant plastic, consisting of the following components in parts by weight: 90 parts of ABS, 95 parts of PC, 10 parts of mica powder, 12 parts of quartz sand, 20 parts of flame retardant, 12 parts of carbon black, 8 parts of soybean oil, 12 parts of corn flour, 3 parts of antibacterial preservatives. Among them, the flame retardant is composed of antimony trioxide, dimethyl trimethylsilyl phosphonate, chlorinated paraffin and molybdenum trioxide in a weight ratio of 2:3:1:2, and the antibacterial antiseptic is composed of silver zeolite , chitosan, and pomegranate peel extract are mixed in a weight ratio of 4:1.5:1.5.

[0019] The products prepared in this example were tested by industry standard experiments, and the results were as follows: the 24-hour sterilization rate of Escherichia coli reached 98.1%, and the 24-hour sterilization rate of Staphylococcus aureus reached 99.3%.

Embodiment 3

[0021] An anti-corrosion and flame-retardant plastic, which consists of the following components by weight: 100 parts of ABS, 75 parts of PC, 15 parts of mica powder, 6 parts of quartz sand, 30 parts of flame retardant, 10 parts of carbon black, 16 parts of soybean oil, 6 parts of corn flour, 6 parts of antibacterial preservatives. Among them, the flame retardant is composed of antimony trioxide, dimethyl trimethylsilyl phosphonate, chlorinated paraffin and molybdenum trioxide in a weight ratio of 4:1:2:1, and the antibacterial antiseptic is composed of silver zeolite , chitosan, and pomegranate peel extract are mixed in a weight ratio of 5:1:2.

[0022] The products prepared in this embodiment were tested by standard experiments in the industry, and the results were as follows: the 24-hour sterilization rate of Escherichia coli reached 98.5%, and the 24-hour sterilization rate of Staphylococcus aureus reached 99.5%.

Abstract

The invention discloses an anticorrosion and flame-retardant plastic. The anticorrosion and flame-retardant plastic is prepared from, by weight, 90-100 parts of ABS, 75-95 parts of PC, 10-15 parts of mica powder, 6-12 parts of quartz sand, 20-30 parts of fire retardant, 10-12 parts of carbon black, 8-16 parts of soybean oil, 6-12 parts of corn flour and 3-6 parts of antibacterial anticorrosion agent. As the fire retardant is high in compound selectivity and flame-retardant efficiency, and the influence of the fire retardant on the physical and mechanical performance of products is small, the compatibility of the fire retardant, the ABS and the PC can be effectively improved, and the fire retardant is even in dispersion and good in heat stability accordingly, and can be used for improving high polymer products needing to be processed and formed at the high temperature; as the antibacterial anticorrosion agent is selected, the poor stability problem caused by purely using a natural bactericidal agent or the pollution problem caused by individually using an organic bactericidal agent or the high cost problem caused by individually using an inorganic bactericidal agent are solved, and as the inorganic and natural bactericidal agent are used in cooperation, the anticorrosion and antibacterial effect is more lasting.
