Description
Technical Field
The invention relates to the technical field of coatings, and particularly relates to a household water-based coating and a preparation method thereof.
Background
The coating is a continuous film which is applied to the surface of an object to be protected or decorated and which can form a firm bond with the object to be decorated. Generally, the coating is a viscous liquid prepared by using resin (or oil or emulsion) as a main material, adding corresponding auxiliary agents, adding or not adding pigments and fillers and using an organic solvent or water. The coating is an important decoration material for home furnishing, along with the development of economy and the improvement of the living standard of people, the functional requirements on the home furnishing coating are more and more, and the use safety and the environmental protection of the home furnishing coating become important indexes for evaluating the quality of modern home furnishing coatings.
With the enhancement of people on improving the household environmental awareness and the stricter requirements of laws and regulations in various places on the environmental protection of the coating, the search for the environmental protection coating becomes a difficult problem which people have to face when coating manufacturers and household decoration of people are decorated. Most of the common coatings on the market at present are solvent-based coatings, and because a large amount of volatile toxic organic solvents are applied in the preparation and use processes of the coatings, serious environmental pollution is caused, and the health of human bodies is directly harmed. Under the situation, the water-based paint is produced at the same time and becomes the mainstream direction for the development of the paint industry at the present stage and for some time in the future.
The water-based paint takes water as a dispersing medium and a diluent, and compared with the organic solvent-based paint, the water-based paint not only reduces the emission of volatile organic solvents, but also saves resources and energy (the solvent is produced to consume the energy), and is convenient to transport and store. Aqueous coating materials can be classified into aqueous emulsion type, aqueous dispersion type and water-soluble type according to the dispersion form of the resin in water. The water-based paint used in the current market generally has the technical problems that a coating film is easy to age, is poor in hardness, cannot effectively protect the strength of a base material, is easy to crack and fall off, has general comprehensive performance, low chemical performance (such as poor alcohol and alkali resistance), low abrasion resistance and other physical indexes. In addition, the water-based paint in the prior art has long drying time and poor flame retardant and heat insulation performance, is not beneficial to energy conservation and environmental protection, and does not meet the strategic requirements of sustainable development.
The Chinese patent with the application number of 201610143904.9 provides a water-based non-stick bactericidal paint which is mainly prepared from the following raw materials in parts by weight: 60-70 parts of polytetrafluoroethylene emulsion, 8-15 parts of acrylic emulsion, 6-8 parts of polyaluminium sulfate, 0.4-1 part of thickening agent, 1-2 parts of catalyst, 1-2 parts of photocatalyst titanium dioxide, 1-2 parts of nano silver oxide, 1-2 parts of dimethylethanolamine, 0-1.5 parts of pearl powder, 0-6 parts of high-temperature-resistant toner and 10-15 parts of deionized water. The water-based non-stick bactericidal coating disclosed by the invention is excellent in non-stick performance, high in bactericidal rate, excellent in air purification effect and good in yellowing resistance. In addition, the water-based non-stick coating has excellent comprehensive performance and strong adaptability to construction environment, reduces the investment of temperature and humidity adjusting equipment, and reduces the construction energy consumption. However, the performance stability and high temperature resistance of the coating are required to be further improved, and the service life of the coating is influenced due to the phenomena of cracking and the like easily caused by poor compatibility among the components in the using process.
Therefore, the development of the home water-based paint with better comprehensive performance, higher bonding performance, better weather resistance, flame retardance, environmental protection, high temperature resistance and stable performance and longer service life meets the market demand, has wide market value and application prospect, and has very important significance for promoting the development of the environment-friendly home paint industry.
