Description
The present invention relates to a kind of waterproof paint composition, particularly relate to a kind of buildings leakproof, antiseepage and moistureproof esters of acrylic acid waterproof paint composition of being used for.
The waterproof problem of buildings not only is related to people's work, living environment, and has influence on the work-ing life of buildings.Therefore, it is that people thirst for the problem that solves always.
Early stage people make water-proof material with tar felt, pitch.Energy consumption height when using this material not only to construct, environmental pollution is serious, poor adhesive force, and also its weathering resistance is poor, and harden easily and embrittlement winter, the fusing of being clamminess easily summer.Therefore, there is constructional difficulties in this water-proof material, work-ing life is short and the problem of water resistance difference.
Since the eighties, people have developed the asphalt waterproofing material with synthetic resins, synthetic rubber modification, as materials such as chloroprene rubber pitch, isoprene-isobutylene rubber pitch and reclaimed rubber rubber asphalts.Though these water-proof materials have brought the convenience in the construction, it still can not solve, and asphalt waterproofing material weather resisteant is poor, work-ing life short and the problem of water resistance difference.
Since the nineties, people make water-proof material with acrylic resin.For example, day clear 60-127374 of disclosure special permission communique (A) has disclosed a kind of binary liquid shape waterproof paint composition.This waterproof paint is formed by a kind of acrylic polymer emulsions and the on-the-spot allotment of a kind of polyvalent metal salt brine solution.Cost is low though this waterproof paint has, and resistance to acids and bases is good, the advantage of good weatherability, not only there is the inconvenient problem of depositing, construct in dual-component coating, and if the on-the-spot allotment of two component ratio improper, can influence the performance of coating.In addition, because in the acrylic polymer emulsions of this waterproof paint, contain acrylonitrile composition, give the synthetic difficulty of having brought of emulsion.
Disclosed a kind of acrylic acid or the like building water-proof paint in the Chinese invention patent ublic specification of application 91111158.1.The tackiness agent of this waterproof paint is formed through radical polymerization in toluene and/or benzene by methyl methacrylate, butyl methacrylate, vinyl acetate between to for plastic and butyl acrylate.Though this waterproof paint can be made single-component coating and use,, not only can damage workmen's health during construction, and can cause environmental pollution because this coating contains toluene or benzene solvent.In addition, because do not contain crosslinkable monomers in this tackiness agent, must influence the physical strength of coating.
It is low to the purpose of this invention is to provide a kind of not only cost, resistance to acids and bases and good weatherability and easy construction, and non-environmental-pollution, good integrity, the rubber-type aqueous waterproofing paint of strong adhesion.
Waterproof paint of the present invention comprises water, filler and acrylic polymer emulsions.Weight with acrylic polymers is benchmark, and described acrylic polymers contains 10-30% (weight) alkyl methacrylate or vinylbenzene or its mixture; 65-80% (weight) alkyl acrylate; 1-5% (weight) N-hydroxyalkyl acrylamide or N-hydroxyalkyl Methacrylamide or its mixture; 1-5% (weight) vinyl unsaturated carboxylic acid or hydroxyalkyl vinyl esters of unsaturated carboxylic acids.Described acrylic polymer emulsions is under tensio-active agent and polymerizing catalyst effect, is that solvent carries out conventional emulsion polymerization and gets with water.
Waterproof paint composition of the present invention can be used as buildings antiseep and finishing material, and particularly suitable is made the water-proof material of building roofing.Waterproof paint composition of the present invention also can be coated on textiles and the paper, to make waterproof fabric and waterproof paper.
Because the esters of acrylic acid soft monomer is 2 with the ratio of hard monomer in the acrylic polymers of waterproof paint composition of the present invention: 1-8: 1, make that like this coating that is formed by waterproof paint composition of the present invention has rubber property.Therefore, this coating has tensile strength height, tension set is big and low temperature flexibility is good advantage.Its tensile strength surpasses national standard about 80%, and tension set exceeds national standard about 40%.
