Embodiment 1～3

[0053] Embodiments 1-3 are a kind of water-based wood coating, and the specific material ratio is shown in Table 1.

Embodiment 4～8

[0063] Examples 4-8, a water-based wood coating, differ from Example 2 in that the emulsifiers are replaced by EL-80, EL-90, TRITON X-405, TRITON X-100, and Pluronic PE 3100 in equal amounts.

Embodiment 9～14

[0068] Examples 9-14, a water-based wood coating, are different from Example 2 in that the specific components are shown in Table 2.

Abstract

The invention relates to the field of coatings, in particular to a water-based wood coating and a preparation method and a use method thereof.The water-based wood coating adopts a combination of a nonionic emulsifier and a water-based acrylic emulsion, and the glass transition temperature of the water-based acrylic emulsion is controlled to be higher than 50 DEG C. According to the scheme, the water-based wood coating has the advantages that the water-based wood coating is prepared; after being coated on the surface of woodware or other materials, the water-based woodware coating can be directly placed in a drying oven to be dried without waiting for leveling, the phenomena of cracking, flaws, miliaria, pinholes and the like are few on the surface, and the water-based woodware coating has the effects of improving the surface flatness of the woodware and reducing the production cost.

Description

technical field [0001] The application relates to the field of coatings, more specifically, it relates to a water-based wood coating and its preparation method and application method. Background technique [0002] Wood coatings have important economic value in today's rapid development of the wood industry. [0003] Water-based wood coatings are a kind of wood coatings. At present, the total station ratio of water-based wood coatings in wood coatings is still low. The reason is that water-based wood coatings are very susceptible to the influence of ambient temperature during construction. It is difficult to balance the performance of thick coating cracking, leveling, sagging, dark bubbles and prickly heat in the environment. [0004] Under normal circumstances, when the temperature of water-based wood coatings is higher than 35°C and the humidity is lower than 30% RH, the above problems will occur. At present, with the use of fast coating machines, the spraying environment ...
