Abstract

The invention discloses an anticorrosive and waterproof coating for wooden furniture and a preparation method thereof in the technical field of waterproof coatings. The anticorrosive and waterproof coating comprises a coating component and a curing component, wherein the mass ratio of the coating component to the curing component is 18-20: 1; the coating comprises the following raw material raw material in parts by weight: 100-120 parts of ultraviolet light cured fluoroalcohol modified epoxy resin, 30-50 parts of an organic solvent, 2-7 parts of a photoinitiator, 3-5 parts of a dispersant, 1-2parts of a leveling agent and 1-2 parts of a defoamer; the curing component comprises the following raw material in parts by weight: 100-110 parts of an amine curing agent, 2-5 parts of an epoxy accelerator and 15-30 parts of an organic solvent. The anticorrosive and waterproof coating for the wooden furniture has good anticorrosive and waterproof properties, and is higher in curing efficiency under the conditions of normal temperature and illumination, simple in preparation process, and convenient to construct and use; and the manufacturing efficiency of the wooden furniture is effectively improved, and good economic benefits can be brought.

Description

technical field [0001] The invention relates to the technical field of waterproof coatings, in particular to antiseptic and waterproof coatings for wooden furniture and a preparation method thereof. Background technique [0002] Furniture refers to the category of utensils and facilities necessary for human beings to maintain normal life, engage in production practice and carry out social activities. Furniture also follows the footsteps of the times and continues to develop and innovate. Up to now, there are many categories, different materials, complete varieties, and different uses. It is an important foundation for building a working and living space. [0003] Wooden furniture: except for decorative parts and accessories among the main components, the rest are made of wood materials such as wood and wood-based panels. Solid wood furniture: furniture made of solid wood sawn lumber or solid wood boards as the base material, with the surface treated; or furniture that is c...
