PC material with super ceramic texture and preparation method thereof

Abstract

The invention discloses a PC material with a super ceramic texture. The PC material comprises the following raw materials in parts by weight: 50 to 60 parts of polycarbonate, 30 to 35 parts of polymethyl methacrylate, 2 to 4 parts of a compatilizer, 6 to 10 parts of ceramic powder, 1 to 3 parts of glass beads, 0.2 to 0.5 part of modified pearl powder, 0.5 to 1 part of titanium dioxide, 0.2 to 0.5part of a light stabilizer, 0.2 to 0.5 part of an antioxidant and 0.3 to 1 part of a lubricant. The invention also discloses a preparation method of the PC material with the super ceramic texture. Compared with an existing ceramic-imitated material, the PC material with the super ceramic texture has the advantages of being high in material hardness, resistant to scraping, environmentally friendlyand capable of being repeatedly used, can present the special silver-white super-ceramic gloss texture, is superior to a conventional ceramic texture in appearance, and is simple in process and suitable for batch production.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a PC material with super ceramic texture and a preparation method thereof. Background technique [0002] With the improvement of people's quality of life, the concept of consumption has also changed. The satisfaction of the basic functions of products is no longer the only criterion for consumers when purchasing household products. Personalized product appearance and novelty have gradually become consumers' considerations when purchasing products. important factor. The appearance of traditional materials such as ceramics, wood, and metal has always been a popular choice for consumers. Therefore, it is of great value and significance to develop a safe, environmentally friendly, scratch-resistant, and super-ceramic-feeling material to solve the current market (especially the home appliance, automobile and bathroom markets) demand for special porcelain-feeling materials. ...

AI Technical Summary

Problems solved by technology

[0003] At present, there are two directions for plastics to achieve imitation ceramic texture: one is to use thermosetting melamine materials to make imitation ceramic parts. High, fast curing, low production cost, rich and easy to obtain raw materials, etc., but this kind of material has the problems of releasing harmful substances such as formaldehyde and melamine, difficult to recycle and not environmentally friendly; the other type is conventional thermoplastic materials or alloys by adding Titanium dioxide and other fillers are used to achieve anti-ceramic effects. Typical patents include CN107746558A, CN110734629A, CN104909617A, CN105153649A, CN104355567A, CN103351589A, CN102617068A, CN102321363A, etc.

The resin substrates in these patents include PBT / PC, PET, PBT, PP / PC / unsaturated resin, PA, PC, PP, etc., but no PC / PMMA alloy is used to prepare ceramic-like texture materials; in addition, these patents The filler materials include ceramic powder, zinc oxide, calcium carbonate, glass fiber, calcium sulfate, potassium titanate, magnesium chloride, metal powder (aluminum powder, iron powder, copper powder), etc. The main functions of these fillers are: one. It is used as a weight-increasing filler (to make the material feel close to ceramic materials); secondly, it is used as an anti-scratch filler (to improve the hardness and scratch resistance of the material). There is no improvement method for improving the texture of ceramics. There is no application of mass-produced high-refraction glass beads and high-reflectivity silver-white pearlescent powder in thermoplastically modified imitation ceramic materials
