Description

Compound paint thinner

Technical Field

The invention relates to the technical field of chemical production, in particular to a composite paint thinner.

Background

When people buy paint coatings, the paint coatings are generally matched with a diluent, the diluent is a liquid substance which is added with good miscibility with resin and is used for reducing the viscosity of the resin and improving the processing performance, and the diluent comprises a reactive diluent and a non-reactive diluent. The thermosetting resin in paint coating needs to be added with thinner to reduce its viscosity for further processing, and these thinner are all organic solvents which are cheaper than resin in practice, so as to reduce the processing cost, however, in the prior art, because the configuration of the thinner is not reasonable, the thinner in the production cannot achieve the required dilution effect, especially for thick paint, and brings loss to manufacturers and consumers.

Disclosure of Invention

In order to solve the technical problems, the invention provides the composite paint thinner, the preparation method is reasonable in configuration, and the prepared paint thinner can meet the dilution requirement and reduce the loss of enterprises and consumers.

The purpose of the invention is realized by the following technical scheme: a composite paint thinner comprising:

(1) the components are as follows: zeolite powder: 55-60 parts; linseed oil: 30-38 parts; sunflower seed oil: 3-8 parts; manganese naphthenate: 1-6 parts; dichloromethane: 0.5-2 parts;

(2) adding zeolite powder, linseed oil and sunflower seed oil into an oxidation kettle according to the corresponding weight part ratio, uniformly stirring, heating to 85 ℃, blowing air into oil through an air pipe to oxidize the oil and automatically heating to 105-110 ℃, continuously blowing air for oxidization at the temperature until the relative density is measured to reach 0.929-0.930, then installing the corresponding weight part ratio, adding dichloromethane and manganese naphthenate, uniformly stirring, and continuously blowing for 35min to obtain the finished product of the oil thinner.
