Abstract

The invention discloses an exterior wall paint prepared from the following raw materials in parts by weight: 86-90 parts of waterborne acrylic emulsion, 17-20 parts of styrene-acrylic emulsion, 20-50 parts of wollastonite powder, 2-3 parts of iso-octyl acrylate, 1-2 parts of potassium borate, 0.4-1 part of ethylene glycol dimethacrylate, 3-4 parts of tungsten boride, 1-2 parts of sodium dodecyl sulfate, 0.6-1 part of dibenzoyl peroxide, 3-4 parts of absolute ethyl alcohol, 0.8-1 part of gamma-aminopropyltriethoxysilane, 0.1-0.2 part of polyoxyethylene polyoxypropylene ether, 3-5 parts of coalescing agent and 10-20 parts of deionized water. The paint produced by the invention is low in raw material loss, less in gel generation, simple in process, firm in paint film, good in glossiness, strong in impact force resistance, not easy to crack, soft in texture, strong in decoration, high in weather and scrubbing resistance, strong in adhesive force, long in service life, free of special smell, heavy metals such as mercury, lead and the like and formaldehyde volatiles, and capable of meeting the technical requirement of an environment-friendly paint; and the added coalescing agent has very high stability, efficient adhesiveness and film forming property, so that the density of the paint film is increased, the film forming quality is improved, and a film layer has the advantages of strong adhesive force, no hole and rift, densification, uniformity and the like.

Description

A kind of environmental protection exterior coating and preparation method thereof
Technical field
The present invention relates generally to a kind of coating, relates in particular to a kind of environmental protection exterior coating and preparation method thereof.
Background technology
In recent years; along with the raising of living standards of the people and the development of society; people are to the selection pay attention to day by day of building decoration coating, and are more simple better to the construction requirement of coating, for particularly in exterior coating; not only rest in the most basic protection to ground; decorative effect to coating is had higher requirement, and exterior coating requires to have water repelling property, requires to have from washing property; it is hard and smooth, dirty once rushing that paint film is wanted.
But the acrylic coating of throwing on the domestic market exists, and gloss is low, poor adhesive force, winter hardiness are poor, not water-fast, water vapour, soda acid, salts solution and organic polar solvent, poor flexibility under the room temperature, the shortcoming such as wear no resistance, and high temperature easily returns sticking, fragile under low temperature splitting, cause coating easily to ftracture, peel off, rainwater etc. easily infiltrate metope, corrosion body of wall, and this not only affects the beautiful decoration of buildings, and will reduce the work-ing life of buildings.
Summary of the invention
The object of the invention is exactly in order to remedy the defective of prior art, exterior coating that a kind of paint film is stable, glossiness is good, tolerance is strong and preparation method thereof to be provided.
The present invention is achieved by the following technical solutions:
A kind of environmental protection exterior coating, it is comprised of the raw material of following weight parts:

Described film coalescence aid is comprised of the raw material of following weight parts:
Nano silicon 30-40, polyvinyl alcohol 4-6, vinyltriethoxysilane 6-10, alkylphenol Polyoxyalkylene ethers 0.8-1, benzene emulsion 3-4, nano-sized carbon 1-2;
Polyvinyl alcohol is joined in the 4-5 times of water, be steam heated to 95-100 ℃, stirring and dissolving adds benzene emulsion, and reducing temperature is 60-70 ℃, constant temperature stirred 3-4 minute, add each raw material of residue, low speed 300-400 rev/min was disperseed 2-3 minute, and 100-120 ℃ of insulation left standstill 1-2 hour, be cooled to normal temperature, namely get described film coalescence aid.
A kind of preparation method of environmental protection exterior coating may further comprise the steps:
The Isooctyl acrylate monomer of above-mentioned weight part is joined in the dehydrated alcohol, stirring and dissolving, the rising temperature is to 80-90 ℃, add sodium lauryl sulphate, benzene emulsion, 500-600 rev/min was stirred 6-8 minute, continued the rising temperature to 90-100 ℃, drip above-mentioned Ethylene glycol dimethacrylate, dropwise rear adding dibenzoyl peroxide, stir, be cooled to normal temperature; Add aqueous acrylic emulsion, deionized water, 900-1000 rev/min was stirred 8-10 minute; Add again wollastonite powder, tungsten boride, stirred 15-20 minute at 700-800 rev/min; Add each raw material of residue, under 600-700 rev/min speed, fully stir, add acetic acid or sodium acetate, adjusting PH is 8-9, stirs to be described exterior coating.
Advantage of the present invention is:
The coating raw material loss that the present invention produces is few, gel generates few, technique is simple, paint film is hard, glossiness is good, anti-impact force is strong, be not easy cracking, texture is soft, ornamental strong, high weather resisteant is arranged, brushing resistance, strong adhesion, long service life, without special odor, not mercurous, the plumbous heavy metal that waits, formaldehydeless volatile matter, meet the technical requirements of environmental protection coating material, the film coalescence aid of adding has very high stability, efficient binding property, film-forming properties has increased the density of coated membrane, improved quality of forming film, so that rete has strong adhesion, without the cavity, split sunken, the fine and close advantage such as even.
