Abstract

The acrylate paint for indoor and outdoor wall consists of water, acrylate or sodium carboxylate as dispersant, acetificated or saponificated mineral oil as lubricant, organic silicon oil as defoaming agent, hydroxy ethyl cellulose as leveling agent, dodecyl alcohol ester, propylene glycol, foamed polyethylene powder as stuffing, lithopone and/or titania powder, talcum powder, light calcium heavy calcium and synthetic polyacrylate emulsion as main component. Then these materials are mixed successively. It has excellent heat isolating performance, high washing resistance, good cracking resistance, high radiation resistance, high adhesion, long service life and other advantages.

Description

A kind of acrylic acid ester paint and production method thereof

Technical field

The invention belongs to a kind of coating for wall surface for building and production method thereof, particularly a kind of have acrylic acid ester paint and a production method thereof heat insulation, heat insulation effect, and this coating especially is fit to do inner, external wall coating and uses.

Background technology

Conventional acrylic acid ester paint as synthetic resin emulsion paint and production method is: the auxiliary agent that at first will comprise water, acrylic acid salt, saponification grease, organic silicone oil, propylene glycol drops into reactor, after the mixing and stirring; Add the filler titanium again from powder (titanium dioxide), upright powder (ZnS), lime carbonate (CaCo ₃), Magnesium Silicate q-agent (Mg ₃(SiO ₃) ₂), and through fully stirring, after mixing; Add acrylate at last---vinylbenzene synthetic emulsion, Natvosol, alcohol ester 12, organic silicone oil, propylene glycol and synthesizing propylene hydrochlorate, again through being stirred to pulpous state.This emulsion paint exists fillibility poor, must wipe body of wall off with putty before the brushing emulsion paint; The anti-width of cloth is penetrated and sun-proof poor performance, does that exterior coating generally promptly can crack about 3 months, the crack, work-ing life defective such as short and heat insulation, heat retaining property difference.

Summary of the invention

The objective of the invention is on basis of background technology, by adjusting its component, proportioning and production technique, penetrate and sun-proof performance to reach the fillibility and the anti-width of cloth that improve coating, strengthen the intensity and heat insulation, the heat-insulating property of coating, purpose such as increase the service life.

Solution of the present invention is on the basis of the component of auxiliary agent and emulsion in adjusting background technology and proportioning, adopts the polyethylene powder as main filler, thereby realizes its purpose.Therefore, coating of the present invention comprises water, auxiliary agent, stopping composition and main composition esters of acrylic acid synthetic latex; Key is that its auxiliary agent comprises acrylate or the carboxylic acid sodium salt as dispersion agent, wetting agent acetify mineral oil or saponification mineral oil, defoamer organic silicone oil, membrane-forming agent alcohol ester 12, flow agent Natvosol, and propylene glycol; Stopping composition comprises polyethylene powder and upright powder or/and titanium dioxide, talcum powder, light calcium carbonate, water-ground limestone; The esters of acrylic acid synthetic latex then comprises synthetic high one's share of expenses for a joint undertaking acrylate pure-acrylic emulsion or/and acrylic ester synthesizing elastic emulsion, vinyl acetate between to for plastic-acrylate synthetic emulsion, tertiary monocarboxylic acid-vinyl acetate between to for plastic acrylic ester synthesizing emulsion; Above-mentioned each composition is by weight percentage: water 10～20%, dispersion agent 0.4～1.6%, wetting agent 0.1～0.5%, defoamer 0.1～0.5%, alcohol ester 12～0.9%, Natvosol 0.1～0.5%, propylene glycol 0.8～2.0%; Stopping composition polyethylene powder 20～55%, water-ground limestone 15～50%, its total solids level are 35～70%; Esters of acrylic acid synthetic latex 10～40%; Mix together through substep.

The production method of above-mentioned coating:

A, at first with water 5～15%, dispersion agent acrylate or carboxylic acid sodium salt 0.2～0.8%, wetting agent acetify mineral oil or saponification mineral oil 0.1～0.5%, defoamer organic silicone oil 0.1～0.5% is during propylene glycol 0.5～1.1% input is stirred after the mixing and stirring;

B, add stopping composition upright powder or/and titanium dioxide, talcum powder, light calcium carbonate, heavy carbonic acid 15～50%; And under the condition of 1400～1600 rev/mins of rotating speeds, mix and stirred 40～60 minutes;

C, add and become owner of composition synthetic macromolecule acrylate pure-acrylic emulsion again or/and acrylic ester synthesizing elastic emulsion, vinyl acetate between to for plastic---acrylate synthetic emulsion, tertiary monocarboxylic acid---vinyl acetate between to for plastic propylene vinegar ester synthetic emulsion, tertiary monocarboxylic acid---vinyl acetate between to for plastic acrylic ester synthesizing emulsion 10～40%, and stopping composition polyethylene powder 20～55%, total solids level should be in 35～70% scopes; Under the condition of 500～600 rev/mins of rotating speeds, mix then and stirred 8～12 minutes;

D, at last Natvosol 0.1～0.5% is dissolved in water the back together with alcohol ester 12～0.9% in 1: 25 ratio, propylene glycol 0.3～0.9%; Add in the lump in the agitator after acrylate or carboxylic acid sodium salt 0.2～0.8% are dissolved in water, continue to stir 10～15 minutes;

Above-mentioned content is the weight percent content of gained the finished product.

Described polyethylene powder, its granularity are 0.15～1.0mm.

The present invention is owing to adopt the bigger polyethylene powder of particle diameter as main filler, and its component of corresponding adjustment, proportioning and production technique, thereby makes this coating not only have good insulation, heat-proof quality, and splitting resistance, the anti-width of cloth are penetrated, abrasion resistance is strong; Be used for not needing Puttying before the cement wall surface spraying, its strong adhesion, can improve 10 times with first-class characteristics work-ing life than background technology.
