Abstract
The present invention relates to a polymer cement base composite water-proof paint for buildings. The paint is a double component product prepared from an organic liquid (component A) and inorganic powder (component B), wherein the component A is prepared from acrylic ester emulsion, siloxane emulsion, dibutyl phthalate, propanediol, sodium tripolyphosphate and tributyl phosphate; the component B is prepared from portland cement, talcum powder and pigments. When used, the two components are mixed at a certain weight ratio to obtain the required composite water-proof paint. With high elasticity and pliability, the paint is suitable for the expansion and the shrinkage of a base surface without cracking. With high adhesive force to various base bodies, the paint can be applied to the construction of a wet base surface without influencing the combination of a water-proof layer and the base surface. The paint which can prevent water integrally is nontoxic, odorless and harmless to human bodies and has no pollution to the environment.
Description
Technical field
The present invention is a kind of composite water-proof paint for building and preparation method thereof.Be specifically related to the high performance polymer cement basis composite water-proof paint of waterproof, antiseep in the engineerings such as a kind of building, bridge, tunnel, underground, roofing.
Background technology
Concrete structure is because its fragility is big, and often inevitable the generation ftractureed in engineering is used.This cracking phenomena will cause the decline of concrete structure watertightness, seepage, influence the work-ing life of engineering, even can't normally use.This is the ubiquitous problem in building circle.Fissured generation mainly contains two big class reasons in the concrete structure, and a class is caused by distortion, comprises because of temperature humidity changes causing contraction, expansion, uneven settlement etc.; Another kind of is that external load (dynamic and static load) direct stress causes.According to statistics, the former is a principal element, accounts for 75%.Produce the rimose analysis of causes from concrete structure and set about, it is imperative to develop novel water-proof material.
At present, water-proof material is numerous, can be divided into rigidity and flexible two big series.Rigid material is firm, be difficult for aging, good weatherability, but should not be used for that engineering deforms, the WATER REPELLENT at displacement position; Though and flexible materials tool flexibility can adapt to the distortion of basic unit, unsatisfactory at aspects such as ageing-resistant, weathering resistance, water tolerance, also should not make the waterproof of back side and moist basal plane.In actual waterproofing work, usually both needed rigidity for material, flexibility is arranged again.Think from concrete structure cracking reason, engineering application characteristic and water-proof material specificity analysis, develop to have and temper toughness with gentleness, existing higher intensity has certain elongation again, be applicable between rigidity basal plane and the flexible waterproof layer that characteristics waterproof paint such as can construct again is very necessary on moist basal plane.
Summary of the invention
The object of the present invention is to provide a kind of composite water-proof paint for building that has rigidity series and flexible serial characteristics concurrently and preparation method thereof.
The composite water-proof paint for building that the present invention proposes, two component products of forming by organic liquid and inorganic powder.Organic liquid component (being designated as the A component) is made up of acrylic ester emulsion, dibutyl phthalate, propylene glycol, siloxanes, tripoly phosphate sodium STPP, tributyl phosphate, and inorganic powder (being designated as the B component) is made up of ordinary Portland cement, talcum powder or flyash, pigment.Weight proportion when A component and B component are used is 0.8: 1～1.4: 1.
Each composition weight proportioning is as follows:
Organic liquid component (A):
Acrylic ester emulsion 1
Silicone emulsion 0.1-0.3
Dibutyl phthalate 0-0.15
Propylene glycol 0-0.07
Tripoly phosphate sodium STPP 0-0.03
Tributyl phosphate 0-0.03
The 4 kinds of components in back are not zero simultaneously.
Inorganic powder component (B):
Ordinary Portland cement 1
Talcum powder or flyash 0.2-1
Pigment 0-0.4
The preferable part by weight of each component is
Organic liquid component (A):
Acrylic ester emulsion 1
Silicone emulsion 0.13-0.16
Dibutyl phthalate 0.04-0.08
Propylene glycol 0.01-0.04

Pigment 0
The present invention is the double-component waterproof coating material that inorganic powder and extraordinary water milk type polymer emulsion are composited.Therefore, be called polyalcohol cement basis composite water-proof paint.Hydration reaction promptly takes place in the water that cement runs in the emulsion in the compound system, forms a certain amount of cement gel body, simultaneously, silicone emulsion is penetrated in the hole of basic unit, and with hydrated cementitious product calcium hydroxide reaction, generate the hydrophobic type product, play closely knit, sealing, waterproof action; And polymer emulsion itself belongs to aqueous colloidal dispersion, and polymer beads wherein disperses in slip, is adsorbed on the surface of cement and hydrated product thereof and other filler.Along with the consumption and the evaporation of moisture, draw close at leisure between the polymer beads and agglomerated together mutually, further curing promptly forms the successive coating structure.This filming based on polymer network structure, cement and hydrated product thereof and other filler are aggregated the thing film and are wrapped in therebetween, the silicate network structure of cement is discontinuous, so coating both had good snappiness and mechanical property, has coating waterproofing and hydrophobic double effects simultaneously.
Preparation method of the present invention is:
The preparation of A component: each component of weighing by weight proportion, successively acrylic ester emulsion, silicone emulsion, dibutyl phthalate, propylene glycol, tripoly phosphate sodium STPP, tributyl phosphate are put into dispersion machine, stir, make oyster white liquid material.
The preparation of B component: talcum powder or flyash filler, pigment are become powder in grinding in ball grinder respectively, then it is added respectively in the ordinary Portland cement, in the powder mixing machine, stir.General stirring got final product in about 10 minutes.
Construction application: weighing A component and B component (0.8: 1～1.4: 1) to scale, then two components are mixed, add water, stir, make waterproof paint.This coating can adopt brushing or spraying to carry out construction in layer.
The present invention has remedied film the again defective of swelling, water-repellancy difference of the flexible deficiency of cement-based material and polymer emulsion, the high-elastic performance of its existing organic coating high-ductility, advantage such as organic and/or inorganic materials good endurance again, the two has reached the mutual supplement with each other's advantages on the performance, plays " complex superposition " effect.Also have advantages such as cohesive strength height, nontoxic, tasteless, no topsoil simultaneously.
The invention has the advantages that:
(1) has higher infiltration water resistance;
(2) have good elasticity and snappiness, can adapt to the expansion and the contraction of basal plane, freely the distortion and do not ftracture:
(3) can construct on moist basal plane, not influence the bonding of waterproof layer and basal plane, also can be used for the WATER REPELLENT of concrete structure upstream face and back side, can adopt technological operations such as brushing or spraying, constructing operation is easy flexibly;
When (4) constructing, no seam has reduced hidden leakage defect, has improved the integral waterproofing effect;
(5) very strong with various bond matrix power, cohesive strength is 5-10 a times of conventional cement mortar.
(6) product is nontoxic, tasteless, and is harmless, free from environmental pollution, belongs to the environment-friendly type waterproof paint.
