Abstract
The invention provides a tung oil modified JS water proofing paint and preparation method, using excellent waterproofness and film-forming property of tung oil. The preparation method comprises : producing modified polyvinyl alcohol by reacting the tung oil with the formaldehyde and polyvinyl alcohol at acid condition; mixing the modified polyvinyl alcohol and acr type latex to a scale; adding dispersant, antifoaming agent to form organic latex; adding organic powder lot produced by mixing portland cement, heavy calcium (or talcum powder), quartz sand; producing water proofing paint. The polymer cement water proofing paint (JS paint) is constituted by two components, with extensibility and waterproofness of polymer coating film, advantages of cement matrix: high strength, easy to bond with the damp substrate, low cost, good workability, and environmental protection.
Description
Technical field
The present invention relates to for building pair of component composite water-proof paint, be specifically related to a kind of be applied to the build high-performance in the construction works such as roof roofing, kitchen, toilet, bridge, tunnel, water reservoir, low-cost modified polyalcohol cement basis composite water-proof paint and preparation method thereof.
Background technology
The architectural waterproof material production of China from single No. 350 petroleum pitch paper fatty oil felts to modified asphalt felt, polymer membranes, rigidity are anti-blends patching materials, have obtained sizable progress.But use the bituminous matter water-proof material, its heat construction contaminate environment, operation trouble and dangerous is also easily aging and work-ing life is short; Polymer membranes is big in the difficulty of construction at complex-shaped position, and is poor with the bonding force of moist basal plane, causes the seam leakiness, the ageing resistance of ointment thereby relatively poor; The anti-patching materials that blends of rigidity easily produces the crack under the situation of formation level deformation, very easily cause because of expanding with heat and contract with cold and leak.China south is subjected to after fifty year return period freezing at the beginning of 2008, the west area, Hunan adopt these conventional waterproof materials building none present large-scale water leakage with escaping by luck.
The JS waterproof paint is the double-component waterproof coating material based on aqueous polymer dispersions and cement, because of its water resistance excellence, easy construction, advantage such as nontoxic are extensive use of the anti-waterborne of construction work, be one of water-proof material of using of the present keypoint recommendation of the Ministry of Construction.Producing the JS waterproof paint on the market has two kinds of methods substantially, and it is the liquid material that the first adopts acrylic emulsion, and another kind is to adopt vinyl acetate-ethylene copolymerization compound (VAE707 emulsion) to make the liquid material in order to reduce production costs.Its water resistance of JS waterproof paint that preceding a kind of method is produced is good, but application cost is higher and workability is not good; The JS waterproof paint that a kind of method in back is produced have good workability and cost lower, but this has congenital defect to make the product water resistance not good on water tolerance because of the VAE707 emulsion.
Summary of the invention
The object of the present invention is to provide a kind of tung oil modified JS waterproofing paint, it has the high water resistance of acrylic acid or the like JS waterproof paint and the low cost of VAE707 emulsion JS waterproof paint concurrently, and hard and soft performance in succession and can construct on complicated basal plane.The present invention also provides a kind of preparation method of tung oil modified JS waterproofing paint.
For achieving the above object, embodiment of the present invention are: a kind of tung oil modified JS waterproofing paint, form by organic emulsion and inorganic powder, and it is characterized in that:
Organic emulsion is made by the raw material of following weight part: 2.5～6.5 parts of tung oil, 2.5～6.5 parts of polyvinyl alcohol, 0.5～1.5 part in formaldehyde, 28.5～38.5 parts in water, 100 parts of acrylic emulsions, 1.0～2.5 parts of dispersion agents, 0.5～1.5 part of defoamer.
Inorganic powder is mixed by the raw material that comprises following weight part: 100 parts of silicate cements, 45～65 parts of coarse whiting or talcum powder, 50～75 parts of quartz sands.
During use, the weight proportion of organic emulsion and inorganic powder is 1: 1～1.5.
The optimum weight proportion of each raw material of product of the present invention is:
Organic emulsion: 100 parts of acrylic emulsions, 4.51 parts of tung oil, 4.51 parts of polyvinyl alcohol, 0.9 part in formaldehyde, 32.95 parts in water, 1.69 parts of dispersion agents, 0.84 part of defoamer;
Inorganic powder: 100 parts of silicate cements, 55.41 parts of coarse whiting or talcum powder, 66.85 parts of quartz sands, 0～2 part of mineral dye.
The weight proportion of organic emulsion and inorganic powder is 1: 1.2.
Preparation method of the present invention may further comprise the steps:
(1) takes by weighing tung oil, polyvinyl alcohol, formaldehyde, water, acrylic emulsion, dispersion agent, defoamer by proportioning, polyvinyl alcohol is added water be warming up to 93～98 ℃ of dissolvings, add tung oil and formaldehyde again and under acidic conditions, carry out condensation reaction to terminal, in dilute sodium hydroxide and after be cooled to room temperature, obtain modified polyvinyl alcohol, then acrylic emulsions and modified poly ethylene alcoholic solution are mixed, add dispersion agent, defoamer, make organic emulsion;
(2) take by weighing silicate cement, coarse whiting or talcum powder, quartz sand by proportioning, mix and make inorganic powder;
When (3) using, organic emulsion and inorganic powder are mixed by 1: 1～1.5 weight proportion, promptly can be made into the tung oil modified JS waterproofing paint product.
Used dispersion agent is preferably polyacrylate.
Used defoamer is preferably organosilicon oils.
The pH value of condensation reaction is 2-4.Condensation reaction pH value of system after neutralizing is 7.
The present invention adopts tung oil-modified polyvinyl formal and the blend of acrylic acid or the like elastic emulsion as the liquid material, utilize good film-forming properties of tung oil and water resistance, and the good unit elongation of polyvinyl formal, replenish mutually with acrylic emulsions, effectively reduce JS waterproof paint liquid material solid content partly, make product both effectively reduce application cost in waterproofing work (actual its waterproof applications cost of measuring and calculating is lower than the JS waterproof paint product that adopts the VAE707 emulsion to make the liquid material), and product of the present invention has good workability, and its water resistance meets and exceeds and adopts single acrylic emulsions to make the JS waterproof paint of liquid material.Product of the present invention all is significantly improved than single esters of acrylic acid JS waterproof paint product aspect cost two in quality.Its major advantage comprises: (1) keeps and has improved extensibility, the water-repellancy of the existing polymer coating film of JS waterproof paint, also has hydraulic cementing materials intensity height, easy and wet base agglutinating advantage simultaneously; (2) have good elongation at break and water-repellancy; (3) product and preparation technology's environmental protection are nontoxic; (4) workability excellence; (5) reduced the application cost of product greatly.
