The invention relates to hot-press-free antibacterial and anti-scraping optical explosion-proof film. Konjac glucomannan nanocrystalline is added into a protection layer and modified through chitosan,the interfacial interaction force among molecules in a formula system is greatly increased, the dispersing performance and the compatibility among components are improved, and thus the mechanical performance of the structure of the protection layer is improved; by adding inorganic and organic compound synergistic antibacterial agents, the antibacterial effect of the protection layer is greatly improved, and cross propagation of bacteria after surface contact of the human body is avoided; the antibacterial and anti-scraping optical explosion-proof film is subjected to hot-press-free curing molding, and the processing procedure and the processing cost are reduced; TPU is good in processability and flexibility and resistant to shock, an optical-grade PET base material is good in optical transparency, the requirement of the explosion-proof film for the optical performance is met, and the light transmittance of the explosion-proof film is increased. The explosion-proof film has good lighttransmittance, static resistance, wear resistance, scraping resistance and bacterial resistance; through the arrangement of the explosion-proof structure layer, the safety and stability during use areguaranteed, and meanwhile the requirement for optical-grade appearance is met.

The invention relates to the field of modification of macromolecular thermoplastic materials, in particular to a modified formula of a high-transparent anti-wear anti-scraping PC (Poly Carbonate) material and a preparation method thereof. The modified formula comprises the following substances in parts by weight: 90-98 parts of PC (Poly Carbonate), 1-5 parts of anti-scraping agent, 0.5-3 parts of lubricating agent and 0.5-2 parts of antioxygen. According to the modified PC formula, the surface hardness of a PC resin is improved on the basis of not changing the mechanical property and the transparent property of the PC resin too much, and the application range in the anti-wear anti-scraping engineering plastic field is expanded. The anti-wear anti-scraping PC material disclosed by the invention has excellent flowability and a simple preparation process.

The invention relates to the field of petrochemical industry, in particular to high gloss wax emulsion for waterborne varnish printing, and a preparation method of the high gloss wax emulsion. The high gloss wax emulsion for waterborne varnish printing is prepared from high density polyethylene wax, Fischer-Tropsch wax, an emulsifying agent, alkali, a wetting dispersant and water; the high densitypolyethylene wax and the Fischer-Tropsch wax are mixed and emulsified; the molecular weight of the high density polyethylene wax is within a range of 500-5000, and the molecular weight of the Fischer-Tropsch wax is within a range of 500-1000; the emulsifying agent is an environment-friendly emulsifying agent which has a cyclic structure and has a carbon number of 10-35. According to the method, the wax emulsion is prepared by mixing and emulsifying the polar oxidized polyethylene wax and the non-polar Fischer-Tropsch wax, and is applied to the waterborne varnish printing, so that a high oilyfeeling and glossiness is provided for varnish, and the surface of the varnish has a high degree of fineness; furthermore, due to smoothness of the Fischer-Tropsch wax, the viscosity, caused by acrylate, of the varnish is greatly reduced, the surface friction coefficient is reduced, and the wear resistance and the scratch resistance are improved; the environmentally friendly emulsifying agent is used and water is used as a solvent, so that pollution caused by adopting NP / OP emulsifying agents in the past is avoided.

The invention belongs to the technical field of building ceramics, and discloses a ceramic material, a digital glaze spraying ceramic rock plate and a preparation method and application thereof, the ceramic material is mainly prepared from quartz, basalt and a flexural strength functional additive, the basalt is beneficial to improving the compactness and the like of the rock plate, sodium humatein the flexural strength functional additive can improve the drying flexural strength of a green body and shorten the drying time of the green body. The invention also provides a digital glaze spraying ceramic rock plate and a preparation method thereof, the main raw material of the rock plate is the ceramic material, and in the preparation method, digital glaze spraying is adopted for surface glaze application, so that the problems that the glaze surface of the ceramic rock plate produced by a traditional glaze spraying mode is too thick, and a relatively obvious white line isolation layer exists from the side view are avoided; and the full-body effect is achieved after the green body is subjected to polishing treatment. The obtained digital glaze spraying ceramic rock plate is more compact, more resistant to fire, high temperature, pollution and corrosion, free of permeation, high in hardness and extremely excellent in scratch resistance and wear resistance, and can be applied to thefields of buildings, decoration and the like.
