Description

Novel environment-friendly paint thinner

Technical Field

The invention relates to the technical field of chemical production, in particular to a novel environment-friendly 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 a novel environment-friendly paint diluent, the preparation method is reasonable in configuration, and the prepared paint diluent 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 novel environmentally friendly paint thinner comprising:

(1) the components are as follows: calcium carbonate: 55-65 parts; ammonia water: 30-35 parts; tung oil: 3-10 parts; dichloropropane: 1-4 parts; cobalt naphthenate: 0.5-2 parts;

(2) calcium carbonate, ammonia water and tung oil are added into an oxidation kettle according to the corresponding weight part ratio, the mixture is stirred uniformly, the mixture is heated to 85 ℃, air is blown into the oil through an air pipe, the oil is oxidized and is heated to 105-plus 110 ℃ automatically, air is continuously blown into the oxidation at the temperature until the relative density is measured to reach 0.929-0.930, then cobalt naphthenate and dichloropropane are added according to the corresponding weight part ratio, the mixture is stirred uniformly, and air is blown continuously for 35min to obtain the finished product of the paint thinner.

The invention relates to a novel environment-friendly paint thinner which comprises the following components in parts by weight: calcium carbonate: 55-65 parts; ammonia water: 30-35 parts; tung oil: 3-10 parts; dichloropropane: 1-4 parts; cobalt naphthenate: 0.5-2 parts; calcium carbonate, ammonia water and tung oil are added into an oxidation kettle according to the corresponding weight part ratio, the mixture is stirred uniformly, the mixture is heated to 85 ℃, air is blown into the oil through an air pipe, the oil is oxidized and is heated to 105-.

Detailed Description

Example 1
