Cement-based material surface permeation protective agent and preparation method thereof

Abstract

The invention discloses a cement-based material surface permeation protective agent and a preparation method thereof and aims at providing a cement-based material surface permeation protective agent which is completely different from the existing surface coating materials and surface hardeners and a preparation method of the protective agent. The cement-based material surface permeation protective agent comprises the following components in percentage by weight; 30%-60% of master batch, 30%-60% of composite silane, 1%-40% of organic solvent and 0%-10% of additives. The permeation protective agent is mainly used for improving the surface protective properties of the cement-based material and enhancing the durability of the cement-based material, and is capable of remarkably enhancing the harmful ion erosion resisting capacity of the cement-based material and also capable of improving the properties such as pollution resistance, salt rust resistance, wear resistance, heat preservation property and waterproof property; meanwhile, the permeation protective agent is capable of reducing the surface defects of the cement-based material such as surface powdering, dropping, frost crack and denudation; the permeation protective agent plays an important role in improving the safety of the cement-based material in the service life period, reducing the later-period maintenance and reinforcement costs and realizing long-term utilization of the cement-based material, and thus has extremely high application value and wide market application prospect.

Description

technical field [0001] The invention relates to the field of building material protection, in particular to a cement-based material surface penetration protectant and a preparation method thereof. Background technique [0002] Cement-based materials include cement concrete, cement mortar, foam concrete, aerated concrete, etc., which are not only the most important main structural materials in the fields of construction, civil engineering, water conservancy, transportation, etc., but also the most important materials in buildings, structures and related civil engineering. Advanced insulation, maintenance, plastering and masonry materials play an extremely important role in the national economy. [0003] With the current comprehensive development of my country's basic construction, problems such as structural maintenance and repair in the later period will become increasingly prominent. Therefore, effective protection of cement-based materials has important practical signific...

Problems solved by technology

[0005] The existing materials with protective effect on the surface of cement-based materials, such as coating protective materials and surface sealing protective materials, because of the thick coating route, it is common that the internal moisture cannot be discharged due to the sealing of the surface pores, resulting in There are a series of problems in thermal insulation performance and adhesive performance, and there are also defects such as coloring
