Abstract

The invention discloses a one-component thermoplastic acrylic paint coating technology. The one-component thermoplastic acrylic paint coating technology includes the following steps that it is ensured that the water content of wood is smaller than 10%, and construction is conducted on a plate which is polished and cleaned thoroughly; through spraying / brushing construction, seal primer is firstly used for completely sealing a white blank twice; after a paint film is dried and is polished and cleaned thoroughly, middle coating primer is directly used, and construction is conducted through spraying / brushing; after the paint film is dried, paint film fullness is obtained in a brushing manner through interlayer polishing and recoating; after the fullness of the paint film is obtained, a matt top coating is directly used, and construction is conducted through spraying / brushing; after the paint film is dried, the paint film fullness is obtained in a brushing manner through interlayer polishing and recoating; and after the top coating is brushed, it is ensured that the paint film is prevented from being touched by the outside before drying is completed. According to the coating technology, the requirement for use of outdoor woodware can be well met.

Description

technical field [0001] The invention relates to a one-component thermoplastic acrylic paint coating process. Background technique [0002] Wood varnishes for outdoor use are composed of three layers, namely sealing primer, intermediate primer and topcoat. The sealing primer has the characteristics of strong permeability and excellent sealing performance. It is used to strengthen the adhesion of the topcoat, making the topcoat more plump, delicate and smooth, and also has anti-corrosion effect. The topcoat is the final coating of painting. The paint effect after decoration or painting is determined by the surface paint rendering. [0003] However, the adhesion, flexibility, hardness, hiding power, wear resistance and scratch resistance of the coating after wood coating in the traditional process are not satisfactory in some environments, especially outdoor environments. Contents of the invention [0004] In order to overcome the deficiencies of the above-mentioned prior a...
