Inorganic and organic composite coating with high elasticity and cracking resistance applied in plaiting crafts

Abstract

The invention discloses an A Inorganic and organic composite coating with high elasticity and cracking resistance applied in plaiting article, the coating is combined in inorganic coating and water-based organic coating to obtain a good film-forming properties and protective properties of inorganic - organic composite coating, the inorganic coating agent used in the composite coating is a graphene-modified lithium silicate composite gel powder, which is better than the conventional lithium silicate film forming agent and has better compatibility with the organic resin, the organic film-forming agent prepared by dispersing the polyurethane dispersion and the natural latex effectively compensates the defects of the inorganic film-forming agent and obtains the superior film-forming effect. The prepared coating can form non-toxic and dense on the surface of the weaving handicraft, high toughness and flexible film to enhance the ornamental value and service life of the crafts, which is economical and practical.

Description

technical field [0001] The invention relates to the technical field of water-based handicraft paints, in particular to a highly elastic and crack-resistant inorganic-organic composite paint for weaving handicrafts. Background technique [0002] Weaving technology is one of the oldest handicrafts of human beings. It processes the stems, leaves and skins of plants, and uses various weaving techniques to weave various daily necessities and handicrafts. These products have a natural, fresh and unique artistic style. The economic value is also gradually increasing, and the market demand is relatively large. [0003] Since the natural weaving materials used in weaving handicrafts are greatly affected by external factors, it is easy to be damaged if no protective measures are taken, which affects the aesthetics and service life of the product. The most widely used and most direct protection method is to coat the surface However, it is different from most products. In addition to e...

Problems solved by technology

[0003] Since the natural weaving materials used in weaving handicrafts are greatly affected by external factors, it is easy to be damaged if no protective measures are taken, which affects the aesthetics and service life of the product. The most widely used and most direct protection method is to coat the surface Coating, however, it is different from most products. In addition to environmental protection, woven crafts also require low production cost, excellent durability, easy cleaning, etc.

Inorganic coatings are a kind of coatings with silicate, silica sol and other inorganic materials as the main film-forming substances. They have good environmental protection, antibacterial and mildew resistance, weather resistance, fire and flame retardancy, etc., and are more suitable for weaving than organic coatings. It is used for handicrafts, but it also has the disadvantages of poor film-forming effect and easy cracking, so its use is limited

The article "Preparation and Performance Research of Lithium Silicate-Based Composite Coatings" discusses the performance of inorganic / organic composite coatings. The film-forming performance of the prepared composite coatings is improved, and the adhesion and strength are also superior. Applied on the mortar substrate, if it is applied to the braided material, there are shortcomings such as insufficient fineness, poor sealing performance, etc., and further improvement is needed
