The invention discloses an aqueous coating for decorating inner walls of antifouling buildings. The aqueous coating comprises the following components in parts by weight: 10-20 parts of deionized water, 0.5-0.8 part of a wetting dispersant, 0.1-0.3 part of a defoaming agent, 1-2 parts of propylene glycol, 15-20 parts of titanium dioxide, 5-8 parts of kaolin, 5-10 parts of talcum powder, 8-10 parts of wollastonite in powder, 2-5 parts of a nano stain-resistant additive, 30-40 parts of nano acrylic emulsion, 0.1-0.5 part of bactericide, 1-2 parts of a coalescing agent, 0.1-0.2 part of a PH adjusting agent and 0.3-0.5 part of a thickening agent. According to the aqueous coating, the nano acrylic emulsion is adopted as a base material, and the functional nano stain-resistant additive is added, so that a coated film has excellent resistance to multiple ordinary dirty marks, the sufficient emulsion use amount together with superfine pigment and packing ensures the tightness of the coated film, stains are effectively prevented from invading and are easy to clean, the coating is very good in adhesion to the base surface of an inner wall, resistant to water and alkali, high in covering property, large in coating area and good in construction performance.

The invention relates to a waterborne polyurethane coating for protection of concrete in cold areas and a preparation method thereof. The waterborne coating consists of a component A and a component B. The component A includes the components by weight: 40 to 70 parts of a waterborne polyurethane dispersion body, 0 to 20 parts of waterborne hydroxyl acrylic resin, 0 to 20 parts of waterborne polyurethane resin, 0 to 10 parts of a waterborne polytetrafluoroethylene emulsion, 0.1 to 8 parts of an auxiliary agent, 5 to 30 parts of pigments and fillers, and 7 to 10 parts of deionized water. The component B is a waterborne isocyanate curing agent with the addition amount of 10-15 parts. The waterborne polyurethane coating can be used normally at low temperature, can prevent concrete from occur water vapor erosion, freeze-thaw damage and other phenomena in cold climate, and slows down natural weathering speed.

An antirust water paint is proportionally prepared from deionized water, anticorrosino agent, antirust agent, defoaming agent, alkali-soluble thickening agent, filming aid, butanediol, disperser, alluminium phosphate, zinc oxide, titanium oxide powder, talc powder, zinc yellow, acrylate emulsion, ammonia water, hydroxyethyl cellulose, and gas-phase SiO2. Its advantages are no environmental pollution and incombustible.

The invention provides a type of marine organism shell powder paint, mainly comprising biosynthesis adhesive, sodium hexametaphosphate, shell powder, emulsifier, and citric acid mono. The marine organism shell powder paint is purely natural, environment-friendly, of simple preparation and of low manufacturing cost, and has no toxic effects on human body.

The invention provides a brand-new pollution-free environmental-friendly full-effective indoor coating and a preparation method and application thereof. The brand-new pollution-free environmental-friendly full-effective indoor coating is mainly refined through excellent formula and process which are summarized through multiple-time experiments by using an environmental-friendly emulsion, multiple environmental-friendly functional auxiliary agents, deionized water, a pigment, a filler, a film-forming auxiliary agent, an environmental-friendly plasticizing agent and the like, ensures that no side reaction is generated among materials, and enables the coating system to be very stable without generating obvious phenomena of after thickening and water diversion. The brand-new pollution-free environmental-friendly full-effective indoor coating provided by the invention is extremely high in performance-price ratio, free of halohydrocarbon substances, pollution-free, environmental-friendly, nontoxic and odorless, can be used for purifying the air by effectively removing indoor odor, has the characteristics of large coating area, good covering power, extremely good lacquer film tactile sensation, good leveling property, excellent scrubbing resistance and the like, meets the requirements for environmental friendliness and technology which are advocated by European Union, America and Japan at present, is on an advanced level of water paint in the same industry, and has good popularization prospects whether in the Europe and America and the Japan or in domestic markets.

The invention discloses SBS universal glue, which is prepared from the following raw materials by mass portion: 62 portions of environment-friendly solvent, 17 portions of SBS, 5 portions of terpine resin, 5 portions of petroleum resin, 5 portions of rosin, 2 portions of filling, 2 portions of antifreeze agent, and 2 portions of age inhibitor. The SBS universal glue prepared by a process has the characteristics of large painting area, environmental protection, high solid content, strong initial adhesion, transparence and good smell, so the SBS universal glue can be widely used in adhesion of an aluminum plastic panel, a fire-proof plate, wood skin, a wood board, and the like.

A compound preparation method of a latex paint with low titanium white and high contrast ratio relates to a preparation method directly applicable to paints for building wall surfaces, and the method comprises the following steps: mixing titanium white powder with water and stirring the mixture; adding a dispersant and a wetting agent; putting the slurry into a mulser for emulsification, and detecting the particle size to be 0.2-0.5 microns; adding a pH adjusting agent to allow the pH to be 7-9; adding a polyurethane thickening agent and an alkali-swelling dispensing agent (to increase the viscosity and realize a stable storage) so as to prepare a titanium white slurry for later use; and adding emulsion paint special powder and an auxiliary agent into the prepared slurry to prepare the emulsion paint. According to the invention, the titanium white power is decreased by 40% under the condition that the same contrast ratio is reached, so the cost of the emulsion paint is reduced about 10-20%; in addition, the paint film is easier to adhere; the painting area is increased; the storage is more stable; and the times for rinsing resistance is also improved.
