Problems solved by technology

Matt paint is widely used in furniture and indoor painting. The gloss of the paint film is soft, non-glare, thin, smooth, acid and alkali resistant, and temperature resistant, but it has poor scratch resistance, poor elasticity, and poor scratch self-healing property. it is good
Nitro lacquer is a very commonly used wood and decorative coating at present. It is easy to construct, dries quickly, has low requirements on the coating environment, has good hardness and brightness, but has a low solid content and requires more construction times. , the benzene solvent used is poisonous, has poor durability, is not resistant to acid and alkali, and is not heat-resistant
[0003] In the prior art, there are not many studies on improving the scratch resistance and flexibility of matt paint, improving the solvent and solid content of nitro paint, and there are still many equipment required, large land occupation, high energy consumption, and production The process is not easy to control, etc.

Abstract

The invention discloses a preparation method of a soft high-solid nitryl flat top-coat paint. The preparation method is characterized by comprising the following steps: preparing materials, orderly adding the solvent, 1 / 2S, 1 / 8S nitrocellulose and maleic resin into a reaction kettle to dissolve, adding soft saturated polyester resin in the reaction kettle to evenly mix, adding polyurethane elastomer, adding delustering agent and plasticizer to disperse to fineness, adding castor oil modified alkyd resin and flatting agent to evenly stir; and filtering, encapsulating and sealing to store. The invention further discloses the soft high-solid nitryl flat top-coat paint prepared by the method; the components comprise the solvent, the nitrocellulose, the maleic resin, the soft saturated polyester resin and the polyurethane elastomer. The preparation method provided by the invention has the advantages of high-solid content, good flexibility, no toxicity, excellent weather resistance, simple technique, quick preparation speed and high efficiency, and can be applied to the protections of metal materials and non-metal materials such as plastics.

Description

technical field [0001] The invention relates to a polymer composite paint, in particular to a preparation method and product of a high-solid flexible nitro matte finish paint applied to various materials. Background technique [0002] With the development of society, various paints and coatings are used more and more widely, and people have higher requirements for decorative paints and coatings. Matt paint is widely used in furniture and indoor painting.
