Abstract

The invention discloses a quartz stone anti-fouling agent and a preparation method and application thereof. The quartz stone anti-fouling agent comprises the following raw materials in percentage by mass: 6-16% of methyl hydrosilicone oil, 2-8% of hydroxyl-terminated polydimethylsiloxane, 0-5% of methyl silicone oil, 1-2% of cosolvent, 0.5-5% of silane coupling agent and 70-85% of solvent. The quartz stone anti-fouling agent is specially developed for coarse and porous quartz stone which is vulnerable to fouling; and by simply smearing the anti-fouling agent on the surface of the quartz stone, the quartz stone can be effectively protected from oil pens, ink, coffee, tea and other pollutants. The quartz stone anti-fouling agent disclosed by the invention is simple in preparation process, good in anti-fouling property and favorable in scrub resistance and durability, can not influence the surface gloss of the quartz stone, and is non-toxic and non-corrosive, thus not only being applicable to the quartz stone, but also being applicable to agglomerated stone, marble, matt tiles and the like.

Description

technical field [0001] The invention belongs to the technical field of quartz stone antifouling, and relates to a quartz stone antifouling agent and its preparation method and application. Background technique [0002] Quartz stone is composed of more than 90% natural quartz (granules or powder, etc.) and about 10% unsaturated resin, colorant and other additives. It is a plate processed by the production method of negative pressure vacuum, high-frequency vibration molding, and heating and curing (the temperature depends on the type of curing agent). Its texture is hard (Mohs hardness 5-7), dense structure (density 2.5g / cm 3 ), has the characteristics of wear resistance, pressure resistance, high temperature resistance, corrosion resistance and impermeability that cannot be compared with other decorative materials. [0003] However, due to some problems in the manufacturing process, the stain resistance of quartz stone is not as good as claimed by many manufacturers. For ex...
