Abstract
The invention discloses a concrete surface permeable coating. The concrete surface permeable coating comprises, by weight, 5-40% of silicate, 10-30% of a silane coupling agent, 0.1-1% of a surfactant and the balance water. The concrete surface is coated with the concrete surface permeable coating, because of capillary action, the concrete surface permeable coating can fast permeate into concrete and form insoluble amorphous hydrated calcium silicate so that concrete structure plugging is realized and surface hardness and wear resistance are improved. The concrete surface permeable coating has a simple and convenient use method, saves time and labor, has no special requirements on a construction environment and conditions and can be widely used for surface treatment on concrete buildings such as roads, squares, supermarkets and workshops. The concrete surface permeable coating reduces a concrete building integrated cost, improves economic benefits and has a wide engineering application prospect.
Description
Technical field
The present invention relates to construction engineering technical field, particularly a kind of concrete surface penetration type coating.
Background technology
Concrete, as the widely used material of construction of one, plays huge effect in modern construction engineering.But concrete is applied to the fields such as factory building, highway, supermarket, garage, after surface drying is shaping, there will be dusting, play dirt, honeycomb and scale phenomenon, surface hardness can reduce, simultaneously also can at generation space, surface even crackle.
For the above problem that concrete exists, modern technologies generally adopt concrete dense curing agent to process concrete surface.Concrete osmosis type curing sealing agent is a kind of multicomponent coating, viscosity is little, is coated in concrete surface and can infiltrates inside concrete very soon due to wicking action, forms insoluble non-crystalline state hydrated calcium silicate, thus realize the shutoff of concrete structure, improve hardness, the wear resistance on surface.But the waterproof effect of existing concrete dense curing agent to concrete structure is not ideal.
Summary of the invention
In order to solve the problem, the object of the invention is, in order to provide a kind of concrete surface penetration type coating, to be coated in concrete surface and can to significantly improve its hydrophobicity and intensity.
To achieve the object of the present invention, the technical scheme of employing is as follows:
A kind of concrete surface penetration type coating, the weight percent of each component is:
Silicate 5% ~ 40%;
Silane coupling agent 10% ~ 30%;
Tensio-active agent 0.1% ~ 1%;
Water surplus, gross weight is in 100%.
Wherein, described silicate is preferably lithium silicate, and lithium silicate modulus is 1.6 ~ 10.0, and lithium silicate modulus refers to SiO in lithium silicate
2with the mol ratio of Lithium Oxide 98min;
Described lithium silicate solid content is 50% ~ 90%;
Described silane coupling agent is γ-epoxypropyl triethoxyl silane;
Described silane coupling agent solid content is 25% ~ 40%;
Described tensio-active agent is fluorocarbon surfactant;
A kind of concrete surface penetration type coating provided by the invention contains silicate, silane coupling agent and tensio-active agent, after this coating is coated in concrete surface, silicate component wherein can penetrate into rapidly that inside concrete and free ca occur to send out should, generate insoluble non-crystalline state hydrated calcium silicate, thus the hole of concrete structure can be blocked, improve its surface hardness.Also reduce to a great extent simultaneously or avoid concrete structure surface and crackle occurs, improve wear resistance and the ultimate compression strength of concrete floor, its water-intake rate of reduced rate.In construction, this coating operations is simple, convenient, saving of labor, saves time, and to construction environment and condition without particular requirement, for the comprehensive cost of concrete structure reduces cost, improves benefit.
