Abstract

The invention relates to an adhesive organic silicon protective agent. The adhesive organic silicon protective agent is prepared from, by mass, 100 parts of a linear body, 10-30 parts of alkyl silane,5-10 parts of amino silane, 5-10 parts of ester silane, 2-8 parts of boric acid, 1-10 parts of a catalyst and 500-1000 parts of 120# solvent oil. The organic silicon protective agent has the advantages of excellent protective performance on ceramic tiles, excellent adhesion, lasting protective effect, and remarkable prolongation of the service life of the ceramic tiles; and a preparation method of the adhesive organic silicon protective agent is simple and easy to implement, and can easily achieve industrial production.

Description

technical field [0001] The invention relates to the field of silicone protective agents, in particular to an adhesive silicone protective agent and a preparation method thereof. Background technique [0002] Ceramic tile is a commonly used decorative material for floors and walls. It has the characteristics of firmness and durability, pressure resistance and wear resistance, smooth and bright surface, good texture and elegant appearance, and is more and more widely used. During the manufacturing process, the adobe or glazed surface of tiles will have pores and tiny cracks, so it is easy to be polluted by sewage, oil, tea, coffee, juice, ink, etc., and the traces left are difficult to erase. [0003] In order to solve this problem, it is necessary to apply a layer of protective agent on the surface of the tiles. Common protective agents mainly include paraffin wax, acrylic resin, and silicone materials. [0004] Although paraffin and acrylic resin can play a protective role...
