Embodiment 1

[0279] An anticorrosion coating for knives, which comprises a basic coating and a silicone resin, the volume ratio of the basic coating and the silicone resin is 1:0.5.

[0280] The invention discloses a preparation method of an anti-corrosion coating for knives. After mixing a basic coating and a silicone resin, the anti-corrosion coating for knives is obtained.

[0281] The volume percentage of the basic coating is as follows: 5% of the pH regulator, 0.001% of the functional catalyst, and 94.999% of the siloxane composition;

[0282] The preparation method of described basic paint, its concrete steps are:

[0283] 1. Control the temperature in the reactor at 40°C, and add the siloxane composition according to the amount while stirring. The stirring rate is 300r / min, and the stirring is slow for about 5 minutes until the mixture is uniform;

[0284] Second, the H in the pH regulator 2 Mix O and the mixed acid evenly in another clean container, and slowly add it dropwise to ...

Abstract

The invention relates to a functional paint, particularly an anticorrosion paint for cutters, which comprises a basic paint and an organic silicon resin in a volume ratio of 1:(0.5-4), wherein the basic paint comprises the following components in percentage by volume: 5-25% of pH regulator, 0.001-0.7% of functional catalyst and the balance of siloxane composition. The functional catalyst is a catalyst containing carbon powder; and the functional catalyst comprises the following components in percentage by volume: 20-60% of zirconate, 1-15% of acetylacetone and the balance of isopropanol. The siloxane composition comprises the following components in percentage by volume: 7-25% of diphenyldimethoxysiloxane, 7-15% of methyltrimethoxysiloxane, 1-5% of gamma-glycidol ether oxypropyltrimethoxysilane, 7-10% of phenyltrimethoxysiloxane and the balance of propylene glycol monomethyl ether. The zirconate, acetylacetone and isopropanol form a space cross-linked structure, thereby being beneficial to controlling the performance of the mild reaction. Compared with the technique of using the single zirconate catalyst, the invention can better control the reaction rate.

Description

【Technical field】 [0001] The invention relates to the technical field of coatings, in particular to a functional coating and a preparation method thereof. 【Background technique】 [0002] The particle size of the pigment in the paint and its dispersibility in the base material will affect the gloss of the paint film. The finer the pigment fineness, the better the uniformity of dispersion in the base material, which helps to form a flat and smooth paint film. The pigment-to-base ratio in the paint affects the gloss of the paint film. The gloss decreases due to the weakening of the specular reflection by the pigment particles in the paint film, and the gloss gradually decreases with the increase of the pigment volume concentration (P.V.C). When the pigment-base ratio is constant, the greater the oil absorption of the pigment, the lower the gloss. Different colors of pigments have different degrees of light absorption and reflection. Because black paint completely absorbs lig...
