specific Embodiment 1
[0032] Waterborne one-component polyurethane open-effect wood lacquer, consisting of the following components: waterborne one-component polyurethane content of 75%, water-soluble cellulose ether content of 7.5%, deionized water content of 17%, water-based silicone The content is 0.5%; the above percentage refers to the percentage containing the total mass.
[0033] The manufacturing process adopted in this embodiment is as follows:
[0034] (1) Prepare raw materials: one-component polyurethane aqueous dispersion, water-soluble cellulose ether, water, water-based silicone;
[0035] (2) Under normal temperature conditions, put into a single-component polyurethane aqueous dispersion, water-soluble cellulose ether, and pure water by percentage in a conventional high-speed disperser to disperse, so that the fineness of the material is less than 40 microns;
[0036] (3) Control the temperature below 50°C, put water-based silicone into the disperser, and disperse at a medium speed f...
specific Embodiment 2
[0040] Fatty acid modified one-component polyurethane aqueous dispersion adopts the product of Germany Bayer (bayer), and the model is VP LS 2342, and its content is 84.5%; Water-soluble cellulose ether is the product of German Clariant Gmbh (Clariant Gmbh), and its content 2%; the content of pure water is 9.5%, and the water-based silicone is mixed by several materials of Byk028, Byk024, Byk346, and Byk381 of BYK Company in Germany, and the content is 3%; the above percentage refers to the content of percentage of the total mass.
specific Embodiment 3
[0043] The water-based one-component polyurethane open effect wood lacquer is composed of the following components: the fatty acid modified one-component polyurethane aqueous dispersion adopts the product of Bayer (bayer) company in Germany, the model is VP LS 2342, and its content is 81%; water-soluble Cellulose ether is a product of Clariant Gmbh in Germany. Its content is 4.5%, and the content of purified water is 13%. Water-based silicone is made by mixing several materials of Byk028, Byk024, Byk346, and Byk381 of BYK Company in Germany. , the content is 1.5%; the above percentages refer to the percentages containing the total mass. The result obtained by the experiment shows that the performance of the product obtained in embodiment 3 is better than that in embodiments 1 and 2.
[0044] This specific embodiment 3 draws the result of the following table through comparing with similar products and through testing: the selected experimental plate is the ash three-plywood.
