Problems solved by technology

Solvent-based acrylic paint and water-based acrylic paint have their own advantages and disadvantages. The paint film of solvent-based acrylic paint is bright and hard, with good color and gloss retention properties, good water resistance and adhesion, and can last for a long time. The paint film dries quickly , good heat resistance, good weather resistance, good outdoor durability, and can be applied under lower temperature conditions. The disadvantage of this paint is that the paint contains a large amount of organic solvents, which will cause harm to the human body and the environment.
Water-based acrylic paint does not contain organic solvents, so it is an environmentally friendly paint, but water-based paint has the defects of slow drying speed, low adhesion and poor heat resistance.

Abstract

The invention discloses a manufacturing method of paint for mechanical equipment. The method includes the steps: firstly, stirring raw lacquer and expandable polystyrene foams in an oxidation polymerization machine to obtain first polymers; secondly, adding low-level ester organic matters, dispersing agents, plasticizers, modified epoxide resins and polyurethane emulsion into a stirrer, adding the first polymers acquired in the step 1, and sufficiently and uniformly stirring mixture to obtain second mixture; thirdly, adding linseed oil serving as dilute solvents into the second mixture, and kneading mixture in a vacuum kneading machine to obtain third mixture; fourthly, adding preservative into the third mixture, uniformly mixing and stirring mixture in a mixer by heating at low temperature, cooling the mixture to the normal temperature to obtain finished products. The prepared paint has higher corrosion resistance, water resistance and oxidation resistance and is low in cost and simple in preparation method.

Description

Technical field [0001] The invention belongs to the technical field of making paint on metal products, and in particular relates to a method for making paint for mechanical equipment. Background technique [0002] Paint is a kind of chemical mixture paint that can firmly cover the surface of objects for protection, decoration, marking and other special purposes. At present, paint is mainly composed of four parts: film-forming substances, pigments, solvents, and additives. The film-forming substance is the basis of the coating. It plays a decisive role in the performance of the coating and the coating film. It has the function of binding other components in the coating to form the coating film. There are many types of substances that can be used as film-forming substances. The contemporary coating industry mainly uses resins, such as alkyd resins, acrylic resins, and chlorinated rubber resins. However, these synthetic resins have the disadvantage of high volatility and easily aff...
