Problems solved by technology

[0004] The object of the present invention is to provide a kind of preparation method of ethyl silicate hydrolysis catalyst and ethyl silicate hydrolyzate, possess catalyst component matching reasonable and raw material easy to get, simultaneously ethyl silicate catalytic hydrolysis reaction is stable, easy to control, through The paint film prepared by using hydrolyzate as the base material of alcohol-soluble inorganic zinc-rich primer, supplemented by conventional pigments and fillers has the advantages of good adhesion, high adhesion, impact resistance, rapid drying, and heat-resistant and anti-corrosion paint film. The hydrolysis process in the existing sol-gel technology has a great influence on the performance of the designed material. If the hydrolysis process is not well controlled, the prepared material is prone to cracking problems

preparation example Construction

[0034] A method of preparing a hydrochloric acid hydrolyzate comprising catalyst configuration, catalyst drop, system holding, hydrolysis control, the preparation process is as follows:

[0035] In the clean high tank, deionized water is first put, then slowly put the zinc inorganic material and mixed acid components in the stirring state, stir evenly to cool to normal temperature, stop stirring spare, and complete the catalyst configuration;

[0036] The polyol (one or several of industrial n-butanol / isopropanol / ethanol) and orthodoxate is sequentially inserted in the clean lower reaction kettle, and the mixing is stirred to stir well, and the reaction is blended

[0037] The low-speed mixed state of the reactant retains the low speed agitation, slightly opens the high canopy of the valve so that the catalyst is slowly added to the lower reaction kettle and the reaction mixture, thereby achieving the catalyst drop, usually dropped within 2-3 hours. After completion, the dripp...

Abstract

The invention discloses preparation methods of an ethyl silicate hydrolysis catalyst and ethyl silicate hydrolysate. The ethyl silicate hydrolysis catalyst is a transparent liquid with a pH value of 2-4 and a water content of 95-99%. The ethyl silicate hydrolysis catalyst comprises the following chemical components by weight: 95-99% of deionized water; 0.5-3% of a zinc inorganic substance; and 0.5-2 percent of mixed acid. The pH value of the ethyl silicate hydrolysate ranges from 2 to 4. According to the preparation methods, the component selection and matching of the catalyst are reasonable, and the raw materials of the catalyst are easy to obtain; ethyl silicate catalytic hydrolysis reaction is stable and easy to control; a paint film prepared by using hydrolysate as a base material of an alcohol-soluble inorganic zinc-rich primer and using conventional pigments and fillers as auxiliary materials has the advantages of good cohesiveness, high adhesive force, impact resistance, rapid drying, heat resistance and corrosion resistance; a hydrolysis process in an existing sol-gel technology has great influence on the performance of designed materials, and if the hydrolysis process is not well controlled, a prepared material is easy to crack, with the ethyl silicate hydrolysis catalyst and the preparation method of the ethyl silicate hydrolysate adopted, the above problems are solved.

Description

Technical field [0001] The present invention relates to the technical field of silicate products, in particular a method of preparing a silicate hydrolysis catalyst and an ethyl silicate hydrolyzate. Background technique [0002] The molecular formula (C2H5O) of the silicate is (C2H5O) 4 · Si, colorless liquid, slightly odor, melting point -77 ° C, boiling point 165 ~ 169 ° C, can be mixed with ethanol and diethyl ether, slightly soluble in benzene, almost insoluble in water Ethyl silicate is an intermediate commonly used in organic synthesis, and the ethyl silicate itself is low, and the action of no binder can be used. It must have a hydrolysis reaction to hydrolyzate to have bonding capabilities. The so-called hydrolyzate is silicic acid. Ethoxy in ethyl ester is gradually substituted by the hydroxyl group in the water, and the process of substituting the product is constantly polycondensation, often said that the ethyl silicate sol - gel method is used by hydrolysis into glas...
