Problems solved by technology

[0006] 1. Wood wax oil is composed of natural vegetable oil and vegetable wax. When it is exposed to oxygen in the air during storage and use, it is prone to oxidative crosslinking, increased viscosity, oxidative discoloration, etc., and the product has a short shelf life.
[0007] 2. The coloring of commercially available wood wax oil is usually done with color essence to ensure good transparency, but the weather resistance of color essence is worse than that of pigments. When it is applied outdoors, its color is easily washed away by ultraviolet light and rain. discoloration and migration
[0008] 3. The drying principle of wood wax oil is that the unsaturated double bonds in natural oils are oxidized and dried with oxygen under the action of driers. Usually, the surface dry and hard dry time is long, and it takes a long time to complete, which affects work efficiency; the market Selling wood wax oil products, in order to speed up the drying speed, usually add cobalt type drier with higher drying efficiency. Although this type of drier has high drying efficiency, its color is darker and not environmentally friendly. It is a European Union Reach regulation. Substances of medium and high concern are not conducive to the export of products; benzene, toluene, xylene, methylene chloride and other toxic solvents such as benzene, toluene, xylene, and methylene chloride can still be detected in some wood wax oil products, or other pungent odor solvents, which cannot be truly achieved Environmental friendly
[0010] None of the above-mentioned patents involves the disclosure of storage stability, weather resistance and beneficial effects of wood wax oil coatings.

Abstract

The invention discloses aerosol paint which comprises, by weight parts, 50-70 parts of modified natural plant oil, 5-10 parts of petroleum resin, 1-5 parts of solid wax, 15-20 parts of solvent oil, 0-20 parts of nanometer color paste, 0.1-2 parts of drier, 0.1-2 parts of flatting agent and 0-5 parts of fumed silica. By adoption of the technical scheme, the aerosol paint has the advantages that oxygen is completely insulated in an aerosol can, product thickening and oxidizing discoloration caused by the reaction with oxygen are avoided, product storage stability is greatly improved, the guarantee period of the product is prolonged, and the aerosol paint has the advantages of being flexible and convenient to construct and excellent in atomization performance. A high-activity iron complex is compounded with zinc isoocatanoate and zirconium 2-ethylhexanoate, MDI modified natural plant oil is optimal, and an oil film is environmentally friendly, quick in drying speed, high in hardness and good in waterproof performance. The aerosol paint is good in permeability, bright in color and good in weather resistance and does not migrate. The invention further discloses a method for preparing the aerosol paint.

Description

technical field [0001] The present invention relates to the field of coatings, in particular to an aerosol paint and a preparation method thereof. Background technique [0002] Due to its good atomization and convenient construction, aerosol paint products have developed rapidly in China in the past ten years and are indispensable in furniture repair and DIY construction. However, wood wax oil aerosol paint products have not appeared on the market. [0003] Wood wax oil is the common name of vegetable oil wax coating in China. It is a kind of natural wood coating similar to paint but different from paint. It is mainly composed of refined linseed oil, palm wax and other natural vegetable oils and vegetable waxes combined with other natural ingredients. . Therefore, it does not contain toxic ingredients such as triphenyl, formaldehyde, and heavy metals, and has no pungent smell. It can replace paint for home decoration and outdoor garden woodwork. [0004] The appearance of ...
