Abstract
The invention relates to polymer cement composite waterproof paint. The polymer cement composite waterproof paint is prepared by modified powder and an emulsion according to a mass ratio being 1:0.8-1.5. The powder of the polymer waterproof paint is specially prepared and is performed with modification processing, so that the prepared polymer waterproof paint has the advantages of good stability, large elongation percentage, high bonding strength, good water resistance, good alkali resistance and good weatherability, can be directly applied on bases without obvious water, and can be widely applied for watertightness for the bases with small activity such as kitchen, toilet, balcony and basement.
Description
Technical field
The present invention relates to technical field of coatings, be specifically related to a kind of polymer cement composite waterproofing paint and preparation method.
Background technology
In the bonding interface of some building slabs of building field, often there is surface cracking, come off, the phenomenon of even member bodies damage in current domestic and international application, thus causes building safety hidden danger to double because of the impact of various factors.Be in particular in: 1, often there will be pasted warming plate, decorative sheet (brick) from obscission external wall in external wall outer insulation engineering and its decorative engineering; 2, the Cement for walls float coat of buildings exterior-protected structure, insulation screed-coat, finish coat, roofing concrete waterproof layer etc. there will be check surface, hollowing, cracking phenomena; 3, the dividing joint of concrete member, expansion joint, movement joint and the pointing mutually bonding with it, jointing material, pointing, Embedding Material etc. occur therebetween coming off, split, hollowing, peeling (in fact, do not damage for the concrete of buildings and matrix material itself, just interface therebetween there occurs separation).
Comprehensive above-mentioned several situation, if cast aside the own quality problems of binder material and building slab, analyze the reason causing occurring these phenomenons, be mainly manifested in: 1 is caused by matrix material and bonded both's temperature varying stress difference, because above-mentioned materials is when envrionment temperature circulation change, produce alternating expansion and contraction, and produce thermal stress and strain, the thermal stress produced along with time lapse (material is aging) in addition and strain once be greater than the bonds itself power of matrix material, just there will be come off, peel off, cracking phenomena.2 be due to concrete cement structure (as finishing cement layer, insulation screed-coat, finish coat, roofing concrete waterproof layer) produce under Influence of Temperature Field thermal stress generation deformation time, after the trickle gap infiltration water inlet occurred, at low temperatures, water freezing volumetric expansion adds large deformation further, thus produces be full of cracks, hollowing, cracking, crack phenomenon.
But above-mentioned these reasons (warm varying stress, thermal stress) be all outwardness, it is the realistic problem do not shifted with the will of people, in order to head it off, in some constructions of construction work, normal requirement on the sticking veneer of component (as warming plate, decorative sheet, decorative block, concrete wall surface, cement surface layer etc.) be coated with and scrape interfacial agents, or roughening surface is carried out to component sticking veneer, soda acid erosion hair interface, the methods such as the flexibility or rigidity of water repellent treatment and increase binding agent, improve its part temperature varying stress, improve the interfacial bond property of building slab.Even so, in actual construction work, the complex process of these methods of Chang Yinwei, consuming time, consume artificial, the technical reason such as by force, the difficulty that operates is large, and artificial interference factor is too many, and quality is difficult to control.So the situation such as quality problems, security incident, potential safety hazard that the interfacial bond property because of building slab produces still occurs repeatedly, it is also customary that architectural exterior-protecting construction produces the phenomenons such as be full of cracks, hollowing, cracking, crack.
