Problems solved by technology

At present, the high-temperature-resistant coatings on the market are mainly solvent-based coatings, which contain a large amount of volatile organic solvents, which not only affect health, but also have serious safety problems.
However, ordinary solvent-free coatings become soft when the ambient temperature exceeds 100 ° C, which brings about disadvantages such as performance degradation.

Embodiment Construction

[0035] The composition ratio of the solvent-free anti-corrosion and high-temperature resistant coatings in Examples 1 to 5 is shown in Table 1.

[0036] Table 1

[0037]

[0038]

[0039] The preparation method of the solvent-free anti-corrosion high temperature resistant coating in embodiment 1 to embodiment 5 is as follows:

[0040] ⑴ Preparation method of component A:

[0041] ①. Add the active diluent and dispersant into the dispersing tank in turn according to the formula amount, and stir at a speed of 300-600 rpm for 3-5 minutes until the dispersion is uniform

[0042] ②. Add epoxy resin and silicone resin, stir at 300-600 rpm for 3-5 minutes until evenly dispersed;

[0043] ③. Add rheological additives, fillers, anti-rust pigments, and high-temperature resistant pigments in sequence, and stir at a speed of 800-1000 rpm for 30 minutes until the temperature reaches 50-60°C. Continue to disperse and keep warm for 30 minutes until fine. The degree is less than 80 m...

Abstract

The invention discloses a solvent-free anti-corrosion high-temperature-resistant coating and a preparation method thereof. Solvent-free epoxy resin, solvent-free organic silicon resin and a reactive diluent are adopted as base materials. Therefore, the coating is free of volatile organic solvents, non-toxic and environment-friendly. The prepared coating has the advantages of strong corrosion resistance, strong adhesive force, high hardness, wear resistance, salt mist resistance, acid and alkali resistance, high solid content and the like, can resist high temperature of 300 DEG C for a long time without cracking and falling off, and has excellent mechanical properties after high temperature.

Description

technical field [0001] The invention relates to an anti-corrosion and high-temperature resistant coating in the field of industrial anti-corrosion, in particular to a solvent-free anti-corrosion and high-temperature resistant coating and a preparation method thereof. Background technique [0002] At present, coatings are being vigorously developed in the direction of green and environmental protection. As one of the main development directions, solvent-free coatings have great room for development. They have excellent anti-corrosion performance, application experience in harsh environments, and mature construction methods. It has great advantages in reducing resources, reducing pollution, reducing physical hazards to construction workers, and implementing national industrial policies. [0003] In the atmosphere, under the action of sunlight and heat, VOC participates in the reaction of nitrogen oxides to form ozone, which leads to poor air quality and is the main component o...
