Abstract

In order to solve the problem of environmental pollution of the conventional coating, the invention provides a novel nano anionic double-component aqueous wood finishing paint and a preparation method thereof. The double-component aqueous wood finishing paint provided by the invention comprises a component A and a component B, wherein the component A comprises the following components in part by weight: 65 to 90 parts of acrylic resin, 0.2 to 0.4 part of antifoaming agent, 0.4 to 0.6 part of composite nano anionic powder, 0.1 to 0.3 part of dispersant, 0.5 to 1.5 parts of thickening agent and 15 to 25 parts of water; and the component B comprises the following component in part by weight: 40 to 60 parts of water-dispersed polyisocyanate, wherein the weight of the component A is 1.5 to 2.5 times that of the component B. The nano anionic double-component aqueous wood finishing paint has the technical advantages of environmental protection, capability of constantly releasing anions and purification and indoor air.

Description

technical field [0001] The invention relates to a coating composition, in particular to a nano-anion two-component waterborne wood topcoat capable of continuously releasing negative ions to purify air and a preparation method thereof. Background technique [0002] At present, due to the limitation of process technology and equipment level of domestic manufacturers, the content of free TDI in the curing agent put into the market is 2%, which is toxic, and some inferior products are even higher. Benzene, toluene, and xylene in the diluent are toxic. Carcinogenic substances, the use of polyester paint containing these substances to decorate home rooms and paint furniture, the toxicity is latent in the paint film and slowly emitted, it will last for 10 years, long-term living in free TDI and toxic environment, light. It can cause neurasthenia, memory, sexual dysfunction, leukocyte thrombocytopenia, and even aplastic anemia, liver cirrhosis, liver cancer, and leukemia, which seri...
