Description
Technical Field
The invention belongs to the technical field of automobile materials, and particularly relates to an antibacterial slush molding skin for an automobile instrument panel, and a preparation method and application thereof.
Background
In recent years, more and more automobile instrument panel skins are prepared by a powder slush molding technology, and the slush molding skins have the advantages of stable size, difficult cracking, uniform thickness, excellent wear resistance, good hand feeling and the like. Polyvinyl chloride (PVC) is used as universal plastic with the largest worldwide yield, has the advantages of low price, stable chemical property, good flame retardance, excellent mechanical property, good electrical insulation property and the like, and is one of the most commonly used raw materials of automobile instrument panel skins.
The antibacterial material is a novel functional material with the function of killing or inhibiting microorganisms. Many substances in nature have good functions of sterilizing or inhibiting microorganisms, such as organic compounds partially carrying specific groups, some inorganic metal materials and compounds thereof, partial minerals and natural substances. However, the existing antibacterial materials are more novel functional materials with the capability of inhibiting or killing surface bacteria by adding a certain antibacterial substance, such as antibacterial plastics, antibacterial fibers and fabrics, antibacterial ceramics, antibacterial metal materials and the like. Antibacterial agents generally fall into two broad categories, inorganic and organic. The inorganic antibacterial agent is prepared by fixing metals (or ions thereof) such as silver, copper, zinc and the like on the surface of porous materials such as fluorite, silica gel and the like by utilizing the antibacterial capability of the metals such as silver, copper, zinc and the like through physical adsorption ion exchange and other methods, and then adding the antibacterial agent into corresponding products to obtain the material with antibacterial capability, wherein the main types of the organic antibacterial agent are imidazoles, thiazoles, halogens, quaternary ammonium salts, bisguanides, phenols and the like. Among them, quaternary ammonium salt antibacterial agents are favored because of their excellent characteristics of low toxicity, low cost, broad-spectrum antibacterial, etc., and are the most widely used organic antibacterial agents at present.
CN111499992a discloses an antibacterial polyvinyl chloride slush molding powder composition, a preparation method and application thereof. The antibacterial polyvinyl chloride slush molding powder composition comprises polyvinyl chloride base powder, a plasticizer, a stabilizer, a pigment, an anti-caking agent and an antibacterial agent. Also provides a preparation method of the antibacterial polyvinyl chloride slush molding powder composition. The antibacterial agent is one or more of nitrile antibacterial agent, ester antibacterial agent, alcohol antibacterial agent, imidazole antibacterial agent, thiazole antibacterial agent, isothiazolinone derivative, and phenol antibacterial agent. The antibacterial polyvinyl chloride slush molding powder composition obtained by the invention has better antibacterial property and can still keep excellent ageing resistance.
CN105218964a discloses an antibacterial polyvinyl chloride material comprising a polyvinyl chloride resin, which comprises the following components per 100 parts by weight of polyvinyl chloride resin as a base resin: 2-10 parts by weight of a combined antibacterial agent, wherein the combined antibacterial agent comprises at least one antibacterial agent A selected from nano titanium dioxide and nano silver-loaded titanium dioxide and an antibacterial agent B selected from polyquaternium antibacterial agents, and the weight ratio of the antibacterial agent A to the antibacterial agent B is 1:3-4:3; a plasticizer B; and C optionally a stabilizer. The antibacterial polyvinyl chloride material has enhanced antibacterial capability due to the inclusion of a specific combined antibacterial agent, and has good mechanical properties.
However, the polyvinyl chloride composition adopts inorganic antibacterial agents such as nano silver oxide and the like simply, has the problems of high price, poor antibacterial performance, poor stability, penetration into human skin, easy loss, secondary pollution and the like, and is limited in wide application to a certain extent.
Therefore, developing an antibacterial slush-molded skin for an automobile instrument panel with high and durable antibacterial effect is a technical problem which needs to be solved in the field.
Disclosure of Invention
Aiming at the defects of the prior art, the invention aims to provide an antibacterial slush-molded skin for an automobile instrument panel, and a preparation method and application thereof.
To achieve the purpose, the invention adopts the following technical scheme:
in a first aspect, the present invention provides an antimicrobial slush-molded skin for an automotive instrument panel, the antimicrobial slush-molded skin material comprising a quaternary ammonium grafted polyvinyl chloride;
