Protection treatment method of stone surfaces

Abstract

The invention discloses a protection treatment method of stone surfaces. The protection treatment method of stone surfaces comprises a step of stone surface pretreatment and a step of waterproof antifouling treatment. According to the step of waterproof antifouling treatment, a stone protective agent is adopted for waterproof antifouling treatment of stone surfaces, wherein the stone protective agent comprises a component A and a component B; the active component of the component A is hydrogen-containing silicone oil; the active component of the component B is long chain alkyl trialkoxysilane.The step of waterproof antifouling treatment comprises following steps: at an environment with a relative humidity of 90% or lower, stone surfaces are uniformly coated with the component A for 3 to 5times at time intervals of 30 to 60min; when A component surface drying is achieved, the stone surfaces are uniformly coated with the component B for 2 to 5 times, and drying curing is carried out for 8 to 24h so as to obtain finished products. The protection treatment method is simple in treatment technology; resource and energy consumption is low; processing period is short; waterproof and antifouling effect is excellent and lasts long.

Description

technical field [0001] The invention belongs to the technical field of stone materials, and in particular relates to a protective treatment process for the surface of stone materials. Background technique [0002] As one of the most commonly used building materials, stone is widely used in various buildings, but under the action of natural factors such as sunlight, weathering and water erosion, stone will be diseased, decomposed and fragmented, which will affect the appearance of stone, especially for The finish color of decorative stone. Especially with the development of industry, there are more serious acid rain phenomena in some parts of the country, which intensifies the degree of stone erosion. For this reason, the prior art uses a stone protective agent to coat the surface of the stone to limit the contact between the stone and the pollution source, so as to achieve the purposes of waterproof, oil proof, acid and alkali resistance, etc. There are many kinds of stone...

AI Technical Summary

Problems solved by technology

At present, the better protective agents used in the market mainly include organosilicon type, organosilicon fluorine type and other penetrating protective agents, which have good antifouling and waterproof properties and are widely used, but if they are wiped after repeated use , its waterproof and antifouling effect will be significantly reduced; although the repeated treatment method can properly improve the waterproof and antifouling performance, it will bring certain damage to the quality of the stone, and will bring more pollution and water resources during the treatment process. and waste of energy resources, labor-intensive and time-consuming, poor economy
