The invention discloses an artificial quartzite plate material which comprises the following components in percentage by total mass of quartzite plate: 60-63 percent of quartz sand with the grain size of 5-100 meshes and inorganic silicon materials of waste glass granules, and the like, 28-32 percent of quartzite powder with 320-3000 meshes, 7-9 percent of unsaturated resin and 0.4-0.6 percent ofpigment and a coupling agent as well as other components in percentage by mass of resin: 0.5-1 percent of ultraviolet absorber, 0.5-1 percent of disintegrant and 0.8-1 percent of curing agent. The invention also discloses the quartzite plate prepared from the raw materials and a manufacturing process thereof. In the invention, the quartzite plate is produced by the steps of vibrating and pressurizing the quartz sand, the quartzite powder, the inorganic silicon materials of waste glass granules, and the like and the unsaturated resin under the vacuum state and curing and synthesizing under theintermediate temperature. The quartzite plate overcomes the problem that the traditional artificial stone is aged under strong lights after long-term use outdoors and has favorable physical and chemical properties.

A process polyvinylidene fluoride membrane is prepared from polyvinylidene fluoride and diphenyl methanone as solvent through lowering temp of system to trigger phase separation. Said porous membrane has no obvious surface structure, spongy cross-section structure and 0.01-1 micron for pore diameter.

The invention is applicable to the preparation of solar cell back film, and provides a blend film containing graphene and a preparation method thereof, wherein the blend film is a blend film of titanium dioxide graft, PVDF, PMMA, PPA and graphene , the titanium dioxide graft is modified titanium dioxide with silane coupling agent KH570 grafted on the surface. Due to the existence of the graft, the present invention overcomes the uneven phenomenon of titanium dioxide in the blended film, and when used for the back film of solar cells, the adhesion between the film and other back plate substrates is also greatly enhanced, PMMA, PPA and graphite The presence of alkene also improves the aging resistance, thermal conductivity and surface smoothness of the back film of the solar cell. The preparation method is: first graft the silane coupling agent KH570 on the surface of titanium dioxide, and then weigh the TiO2 according to the mass ratio. 2 The graft, PVDF, PMMA, PPA, and graphene are mixed, stirred evenly, extruded into strips, cut into pellets, dried, and casted by single-screw extrusion to obtain the blended film.

The invention relates to an epoxy coal asphalt anti-corrosion paint, comprising a component A and a component B, wherein the component A is composed of E-42 type bisphenol A-type epoxy resin, dimethyl benzene, butanol, butanone, coal asphaltic resin, toughening resin, precipitated barium sulfate, sericite in powder, talc powder, associative rheological control auxiliaries, Isopropyl tri(dioctylpyrophosphate)titanate, fluorocarbon macromolecular compound and organic silicon defoamer; the component B is composed of cashew mannich amide, 2,4,6-Tris(dimethylaminomethyl)phenol, alcohol and hydroxybenzene benzotriazole ultraviolet absorber; the mass ratio of A to B is 10:1; and the paint can be used after A and B are evenly mixed. The epoxy coal asphalt anti-corrosion coating has the toughness,which is used for anti-corrosion for a PCCP outer wall, has excellent adhesive force, good microorganism corrosion resistance and long period of use and has certain light aging resistance.

The invention discloses a skin care matrix for resisting external pressure and protecting DNA, a preparation method and application thereof. The skin care matrix includes the following components in mass percentage: 10-20% of 1,3-butanediol, 5-30% of purslane extract, 5-30% of artemia extract, polysodium γ-glutamate 1 ~5%, sodium hyaluronate 0.5‑2%, and the balance is water. The skin care matrix of the present invention achieves good anti-inflammation and anti-photoaging effects through the synergistic effect of the functional components of purslane extract and Artemia extract, effectively reducing the formation of wrinkles and the loss of skin elasticity. Improves skin fine lines and protects DNA at the same time. At the same time, the preparation method of the skin care base provided by the present invention is simple, easy to operate, and the active ingredients are fully released, which can ensure the final skin care base product with uniform properties and stable quality. The preparation method is scientific and standardized, easy to operate, and suitable for standardized production and promotion. application.

The invention provides a novel antibacterial radiation-proof silver-impregnated fiber fabric and a preparation method thereof. The preparation method of the novel antibacterial radiation-proof silver-impregnated fiber fabric comprises the following steps: (1) immersing the fiber fabric in an antibacterial silver solution, dipping 20-50 minutes, drying; (2) immerse the fiber fabric in the water-resistant finishing solution, soak for 30-60 minutes, and dry to obtain a novel antibacterial and anti-radiation silver-impregnated fiber fabric. The beneficial effect of the present invention lies in: overcoming the problem that metallic silver is only distributed on the surface of fibers and fabrics in the traditional technology, and is not resistant to washing, rubbing, oxidation, friction and conduction instability. The novel antibacterial and anti-radiation silver-impregnated fiber fabric of the present invention can distribute the fibers and fabrics in a silver state from the inside to the outside, and the formed metallic silver has a high density and is resistant to washing, rubbing, oxidation and friction. Applications are not limited to: medical, clothing, home textiles, national defense, aviation, automobiles, anti-static work clothes, wrist straps, printers, air conditioning filters, etc.
