Description
Technical field
The present invention relates to building decoration area, more particularly to a kind of polymer cement-base waterproof coating.
Background technology
Polymer cement-base waterproof coating, also known as JS composite water-proof paints.Polymer cement-base waterproof coating is based on organic
Polymer emulsion dehydration, and formed and absorb the water in lotion with cohesiveness, successional layers of elastomeric film, cement and harden, it is soft
Property polymer and hardening of cement body mutually run through and be bonded to a firm flexible waterproof layer securely, flexible polymer is filled out
Fill in the gap of hardening of cement body, make that hardening of cement body is finer and close and high resilience, film have preferable elongation percentage, water
Mud hardenite is filled in polymer phase again, it is had more preferable outdoor durable and more preferable basic unit's adaptability.Therefore it is existing
Certain rigidity, and there is certain toughness, and there is very high caking property, coating can be made very thin, along with this
Water-repellent paint is a kind of Environmentally friendly coatings, and environment is not impacted, so increasingly being favored be subject to people, becomes near
The hot spot of in the past few years water-repellent paint development.But existing coating is gone back in terms of intensity, anti-aging property and water resistance is drawn high
Need further to be improved.
The content of the invention
In order to solve the above technical problems, the present invention provides a kind of polymer cement-base waterproof coating, ethyl vinyl acetate is used
The mixed emulsion of ethylene polymer emulsion and vinyl acetate-acrylate copolymer emulsion, draw high intensity, anti-aging property and
Improved in terms of water resistance, solve existing polymer cement-base waterproof coating draw high intensity, anti-aging property and
In terms of water resistance the problem of deficiency.
To reach above-mentioned purpose, technical scheme is as follows：A kind of polymer cement-base waterproof coating, including with matter
Measure the following raw material of number metering：
As a preferred embodiment of the present invention, present invention additionally comprises thickener, the thickener is 1-3 parts.
As a preferred embodiment of the present invention, the coalescents are Lauryl Alcohol ester.
As a preferred embodiment of the present invention, the defoamer is organic silicon modified by polyether.
As a preferred embodiment of the present invention, the levelling agent is polyether-modified dimethyl silicone polymer.
As a preferred embodiment of the present invention, the talcum powder is 200-400 mesh.
As a preferred embodiment of the present invention, the water-reducing agent is polycarboxylic acid.
As a preferred embodiment of the present invention, the dispersant is calgon.
As a preferred embodiment of the present invention, the present invention includes the following raw material measured with mass fraction：
Through the above technical solutions, the beneficial effect of technical solution of the present invention is：The present invention is gathered using ethene-vinyl acetate
The mixed emulsion of compound lotion and vinyl acetate-acrylate copolymer emulsion, can play collaboration facilitation, in cement water
, can be mutually cementing with hydrated cement slurry during change, finer and close net structure is formed, substantially improves Portland cement base
Physical organization's structure of material, alleviates internal stress, reduces the generation of micro-crack, strengthen the compactness and mechanics of polymer waterproof coating material
Performance, elasticity is more preferable, and elongation percentage is more preferable；Waterproofing agent of organosilicon and nano silicon dioxide coordinate, and can penetrate into inside film layer
At rift defect, and reacted with portland cement base material, generate new gel and hydrophobicity product, block capillary porosity
Passage, and make to be not easy to be spontaneously wet out by water at rift defect, the intensity of film layer is further improved, forms integral waterproofing layer.Ultra-fine carbonic acid
Calcium powder can suitably reduce the ratio of mud, and the reduction of the ratio of mud means being greatly lowered for pore volume, to improve strength of cement,
The performances such as impermeability have larger contribution；Coalescents improve wetability of the lotion to fillers such as cement and talcum powder, make painting
It is stronger that intensity is drawn high after material film forming；Epoxy resin helps to improve the anti-aging property of film layer, improves the durability of film layer, at the same time
The heat-insulating and fire-proof performance of film layer can be lifted.
