Problems solved by technology

[0002] Unsaturated polyester paint for wood products usually has four components, namely main paint, initiator (commonly known as white water), accelerator (commonly known as blue water) and reactive diluent. Finally, the surface needs to be sealed with wax (or film) (if it is air-dry, it can not be sealed), and after curing, it can be finished by machine grinding, polishing and other processes, so the process is more complicated and the price is higher, but its paint film It is hard and plump, so it is mostly used for the top coat of high-end furniture and audio casings with high decorative requirements; while the common polyurethane paint in the market is a two-component one, one is the main paint, the other is the curing agent, and it is used according to the requirements. The ratio is mixed, and an appropriate amount of thinner is added, and the construction can be carried out after stirring evenly. The process is simple, but some technical indicators are not excellent enough. Construction in high humidity environment is prone to foaming, and the requirements for substrate treatment are relatively high, such as the dryness of wood, etc.

Abstract

The invention relates to a modified unsaturated polyester colored finish paint or primer, which is characterized in that: the paint is prepared by mixing a polyurethane component with an unsaturated polyester component according to a weight prescribed ratio of polyurethane component to unsaturated polyester component of 1: (0.5-1). Compared with the prior art, the modified unsaturated polyester colored finish paint or primer has excellent technical indexes and can replace foreign similar products, and has the advantages of high hardness, good fullness, strong adhesion, good flexibility, easiness in construction and the like.

Description

technical field [0001] The invention relates to the technical field of paint for wood products, more specifically relates to a novel colored topcoat or primer for wood products with good decorative effect. Background technique [0002] Unsaturated polyester paint for wood products usually has four components, namely main paint, initiator (commonly known as white water), accelerator (commonly known as blue water) and reactive diluent. Finally, the surface needs to be sealed with wax (or film) (if it is air-dry, it can not be sealed), and after curing, it can be finished by machine grinding, polishing and other processes, so the process is more complicated and the price is higher, but its paint film It is hard and plump, so it is mostly used for the top coat of high-end furniture and audio casings with high decorative requirements; while the common polyurethane paint in the market is a two-component one, one is the main paint, the other is the curing agent, and it is used acco...
