The invention provides a wear-resistant high-brightness reflective hot-melt marking paint, which belongs to the field of road marking construction. The marking line is divided into surface layer and bottom layer, and also contains glass beads. The glass beads are located between the surface layer and the bottom layer. The schematic diagram of the marking line structure is as follows, where a is the surface layer, b is glass beads, and c is the bottom layer. Specifically, the surface layer is made of hydroxymethyl cellulose, nitrocellulose, acrylic resin, ethyl cellosolve acetate and polyethylene wax, which has high transparency and high wear resistance; the bottom layer is made of titanium dioxide, Fusion made of petroleum resin, plasticizer, EVA, PLA‑PEG and aluminum oxide flakes, it is highly reflective and has high adhesion to glass beads. The hot-melt marking paint provided by the invention has long-lasting and high reflection, and its actual performance is higher than the requirements of existing standards.

The invention provides chloroplatinic acid slurry and a preparation method and an application thereof. The chloroplatinic acid slurry per 100g comprises 5.84-21.5g of chloroplatinic acid, 38.34-61.55gof one or more compounds of terpineol, kerosene, high boiling paraffin oil and ethylene glycol monomethyl acetate, 4.15-13.51g of ethylcellulose and inevitable impurities. In the preparation processof the chloroplatinic acid slurry, one or more compounds of terpineol, kerosene, high boiling paraffin oil and ethylene glycol monomethyl acetate and ethylcellulose are used to regulate the viscosityof the chloroplatinic acid slurry to meet the demand of the application of the slurry. The obtained chloroplatinic acid slurry has higher viscosity so that the chloroplatinic acid slurry can be directly used to prepare the counter electrodes of dye-sensitized solar cells by screen printing.

The invention discloses a method for preparing a corrosion-resistant and anti-scaling composite coating on a water wall of a waste-to-energy plant, belonging to the field of new material preparation. The technical scheme is as follows: mix and stir the mass fraction of acrylic acid of 40%, the mass fraction of acetic acid of 10% and the mass fraction of propyltrimethylsilane of 50% in a mixer at 120° C. to prepare the mixture A. The cross-linking agent is prepared by mixing and stirring the cross-linked acetic anhydride with a mass fraction of 50% and the mixed amide with a mass fraction of 50%. Then mix and stir ethyl cellosolve with mass fraction of 50% and diacetone with mass fraction of 50%, then add crosslinking agent with mass fraction of 20% and stir for 20 minutes to prepare mixture B. and many more. After coating, dry at a temperature of 180‑500 for 3 hours to form a semi-metallurgical bond with a bond strength of 230Mpa. Compared with the prior art, the coating material prepared by the present invention has a high temperature resistance of up to 800°C, a bonding strength of 230Mpa, a penetration function, a surface hardness of HV800, wear resistance and corrosion resistance (15% hydrochloric acid resistance), anti-sticking function, and Absorbs heat energy and has a long service life.

The invention discloses heat-curing heat-conduction heat-dissipation paint and a preparation method thereof, belonging to the field of heat dissipation paint. The paint comprises the components by weight percent: 25-30% of acrylic acid resin, 25-30% of nitro-cotton resin, 15-20% of solvent, 2-4% of auxiliary agent, 2-3% of coloring agent and 20-30% of inorganic filler, wherein the solvent comprises the components: butyl acetate, n-butyl alcohol and ethyl cellosolve according to the mass ratio of 2: 2: 1. The preparation method comprises the steps of: evenly mixing the butyl acetate, the n-butyl alcohol and the ethyl cellosolve; dissolving all the acrylic acid resin and nitro-cotton resin into the mixed solvent, and mixing the mixture with the coloring agent; evenly stirring at room temperature to form paint vehicle; and grinding, dispersing, adding the inorganic filler into the paint vehicle, evenly stirring and stabilizing to obtain the target paint. The heat-curing heat-conduction heat-dissipation paint has excellent flame retardant performance, insulation property, high temperature resistance and corrosion resistance, so that the heat-conduction heat-dissipation effects of the coating using the heat-curing heat-conduction heat-dissipation paint are obviously improved compared with the common coating.

The invention discloses a method for producing environmentally friendly paper PU for office furniture. 80-100 parts of polyurethane surface layer resin without dimethyl fumarate, 40-70 parts of ethyl cellosolve, 0.5-2 parts of assistant 80-100 parts of polyurethane adhesive resin without dimethyl fumarate, 20-60 parts of ethyl cellosolve, 0.5-2 Parts of additives and 5-8 parts of environmentally friendly toner are mixed to obtain dry-process adhesive; the dry-process fabric is coated on the release paper, and after drying, the dry-process adhesive is coated on it, and the solvent is volatilized to 40 ‑80% dry, paste the base paper on the surface of the dry-process adhesive, dry, cool, and separate from the release paper to obtain the finished product. The finished product obtained by the present invention does not contain dimethyl fumarate (DMF), which is environmentally friendly , does not harm human health, and the overall thickness is thin, soft and tough, bright in color, bright in pearl, strong and durable.
