Nitrocellulose-modified low-temperature quick-drying unsaturated polyester primer and preparation method thereof

Abstract

The invention relates to a nitrocellulose-modified low-temperature quick-drying unsaturated polyester primer and a preparation method thereof. The nitrocellulose-modified low-temperature quick-drying unsaturated polyester primer is prepared by mixing a main paint, an initiator and an accelerator at a weight ratio of 100:(1.0-1.2):(1.2-1.5), wherein the main pain is prepared from the following components in parts by weight: unsaturated polyester resin, a defoaming agent, a leveling agent, transparent powder, talc powder, fumed silica, zinc stearate, an anti-greening agent, a drying agent, acetone, ethanol, nitrocellulose solution and styrene, the initiator is cobalt naphthenate, and the initiator is methyl ethyl ketone peroxide. The nitrocellulose-modified low-temperature quick-drying unsaturated polyester primer prepared by adopting the preparation method can be sprayed under the environmental condition of low temperature, and the formed covering can be dried at a very high speed and has excellent adhesion and fullness.

Description

technical field [0001] The invention relates to a coating for furniture, in particular to a nitrocellulose-modified low-temperature quick-drying unsaturated polyester primer and a preparation method thereof. Background technique [0002] At present, the development of unsaturated polyester furniture paint is very rapid, especially in the decorative coating of furniture such as kitchen cabinets, bathrooms, and display cabinets. In the decorative coating of normal furniture, the construction environment temperature of unsaturated polyester paint is lower than 10 degrees The reaction speed becomes very slow at the following times, and the construction efficiency is low; in order to increase the drying speed, only the environment is heated to promote drying. [0003] Now, there are few unsaturated polyester primers on the market that can be used directly in a relatively low temperature environment without heating up when the construction environment temperature is low. Therefor...

AI Technical Summary

Problems solved by technology

[0002] At present, the development of unsaturated polyester furniture paint is very rapid, especially in the decorative coating of furniture such as kitchen cabinets, bathrooms, and display cabinets. The reaction speed below becomes very slow, and the construction efficiency is low; in order to increase the drying speed, only the environment is heated to promote drying

[0003] At present, there are few unsaturated polyester primers on the market that can be used directly in low-temperature environments without heating up when the construction environment temperature is low

Therefore, it is an urgent task to solve the problems of slow drying speed, low construction efficiency and high production cost of UPE unsaturated polyester primer directly applied in low temperature environment.
