Environment-friendly antibacterial polypropylene material special for sprayers and preparation method of material

Abstract

The invention is applicable to the field of polypropylene materials, and particularly relates to an environment-friendly antibacterial polypropylene material special for sprayers. The material comprises the following components in parts by weight: 40-70 parts of wood pulp fiber treatment material which comprises a colloid adhesive, wood pulp fiber and quartz sand; 15-27 parts of a dispersant; 5-9parts of an antioxidant; 18-28 parts of rubber in which protein is added; and 80-120 parts of a polypropylene base material. Holes are densely distributed in the surface of the wood pulp fiber, afterquartz sand vibrates, disperses and enters, the advantages of high rigidity and high resilience matched with the wood pulp fiber are achieved by utilizing the colloid adhesive, namely, the wood pulp fiber treatment material can be recovered after the rigidity is damaged, and meanwhile, the effects of rubber and the polypropylene base material are combined, so that on the basis of high rigidity, quick restoring force is realized, and residual liquid materials are not easy to cause and bacteria are not easy to breed.

Description

technical field [0001] The invention is applicable to the field of polypropylene materials, and in particular relates to an environment-friendly and antibacterial polypropylene material specially used for sprayers and a preparation method thereof. Background technique [0002] Polypropylene, referred to as PP, is a colorless, odorless, non-toxic, translucent solid substance; polypropylene (PP) is a thermoplastic synthetic resin with excellent performance, which is a colorless and translucent thermoplastic lightweight general-purpose plastic. [0003] Polypropylene has chemical resistance, heat resistance, electrical insulation, high-strength mechanical properties and good high wear-resistant processing properties, etc., which makes polypropylene rapidly used in machinery, automobiles, electronic appliances, construction, textiles , packaging, agriculture, forestry, fishery and food industry and many other fields have been widely developed and applied. And because of its pla...

Problems solved by technology

[0006] And the polypropylene material in application sprayer field has all increased antimicrobial agent in existing prior art, so that can antibacterial well; But often ignore the character of polypropylene material itself, for example the PP material of copolymer type has lower High heat distortion temperature (100°C), low transparency, low gloss, low rigidity; after the material is impacted and dented, the dented recovery is slow and easy to leave liquid material, although the polypropylene material added with antibacterial agent is not easy to breed bacteria, but the residual liquid The material is easy to breed bacteria and is not easy to be antibacterial; although the Vicat softening temperature of PP is 150°C; due to the high degree of crystallinity, the surface stiffness and scratch resistance of this material are very good; PP does not have the problem of environmental stress cracking; flexibility and rigidity It is inversely proportional, but after being impacted by the critical point, it will still deform, but the deformed material will still have sags, and the sags will recover slowly, leaving liquid materials, breeding bacteria, and not easy to antibacterial
