Abstract

The invention discloses waterproof elastic latex paint for a building external wall and a preparation method of the waterproof elastic latex paint. The waterproof elastic latex paint is prepared from the following raw materials in parts by weight: 35-40 parts of elastic acrylic emulsion, 3-5 parts of waste glass fiber, 18-22 parts of nano-silica, 6-8 parts of clay, 8-10 parts of rectorite, 7-9 parts of pearl wool leftover material, 103-107 parts of water, 2-3 parts of emulsified asphalt, 1-2 parts of lecithin, 2-3 parts of carboxymethyl cellulose, 2.5-3.5 parts of sodium bicarbonate, and 1-1.5 parts of diethylene glycol monobutyl ether. According to the invention, the elastic acrylic emulsion is used as a film formation base material, and is matched with added emulsified asphalt, so that the adhesiveness and waterproofness are improved; the processed waste glass fiber, clay and rectorite are added to change the surface tension, and can be better mixed with the emulsion, and the film of the prepared paint is excellent in elasticity and durability, good in waterproofness and stain resistance, and not easy to crack.

Description

A kind of water-proof elastic latex coating for external wall and preparation method thereof
Technical field
The present invention relates to a kind of coating and preparation method thereof, particularly a kind of water-proof elastic latex coating for external wall and preparation method thereof.
Background technology
When being used as exterior coating, the very short internal structure such as time inner concrete, fragment of brick can because climate change bring the phenomenon of expanding with heat and contract with cold to rigidity coating, and various body of wall is because of the degree difference of expanding with heat and contract with cold, and can produce internal stress.When internal stress is applied to the globality that namely surface of wall can affect exterior wall film, thus there is the phenomenon of cracking, foaming, even fall in flakes.There is elastic exterior coating to be out of shape along with expanding with heat and contract with cold of body of wall, and then keep the continuity of film, keep whole structure for a long time.But elastic exterior coating material has two larger shortcomings: one is that the bond effect of film and body of wall is poor, because the cohesive force only having the elasticity of film self to be greater than film and ground just can produce recoverable deformation, otherwise the effect of the coating that will follow the string; Two is that elasticity film coated surface specific rigidity film viscosity is large, when film is subject to exposing to the sun and rain outer, is easily bonded on film, and affects appearance of film when dust etc. fall.So when elastic exterior coating material carries out large-scale application, make great efforts the waterproof pollution resistance and the viscosity that solve elastic emulsion coating.
Summary of the invention
The object of this invention is to provide a kind of water-proof elastic latex coating for external wall and preparation method thereof.The present invention adopts elastomeric propylene yogurt liquid as film forming binder, coordinates the interpolation of emulsified bitumen, enhances binding property and water-repellancy; Add scrap glass fiber, clay, the rectorite leng after process, change surface tension, can better mix with emulsion, the coating made is coated with film elasticity, and good endurance, water-proof stain-resistant is good, not easy to crack.
In order to realize object of the present invention, the present invention is by following scheme implementation:
For a water-proof elastic latex coating for external wall, be made up of the raw material of following weight part: elastomeric propylene yogurt liquid 35-40, scrap glass fiber 3-5, nano silicon 18-22, clay 6-8, rectorite leng 8-10, PE Foam scrap stock 7-9, water 103-107, emulsified bitumen 2-3, Yelkin TTS 1-2, carboxymethyl cellulose 2-3, sodium bicarbonate 2.5-3.5, butyl carbitol 1-1.5;
A kind of water-proof elastic latex coating for external wall of the present invention, be made up of following concrete steps:
(1) scrap glass fiber, rectorite leng are ground into 200 order powder, then with clay mixing and ball milling 20 minutes, water and the Yelkin TTS of 3 times amount is added in the mixed powder after ball milling, dispersed paste is formed after stirring 40 minutes with the speed of 600 revs/min, again by dispersed paste spraying dry, control spray-dired inlet temperature 150-180 DEG C, temperature out 60-75 DEG C, obtain surface active filler;
(2) carboxymethyl cellulose is added in the water of 3 times amount, be stirred to formation clear solution, then granulation in tablets press is jointly joined with surface active filler, sodium bicarbonate in step (1), the particle obtained first is sintered 60 minutes at the temperature of 220-250 DEG C, then 500-550 DEG C of sintering 2-2.5 hour is warming up to, be ground into 250 orders after being cooled to room temperature, obtain mixed powder A;
(3) PE Foam scrap stock are ground into 200 orders for subsequent use, the water of residual content is joined in dispersion cylinder, elastomeric propylene yogurt liquid, emulsified bitumen is slowly added under the rotating speed of 450-500 rev/min, disperse after 30-40 minute, improve rotating speed to 800 rev/min, add the PE Foam scrap stock after the mixed powder A of step (2), pulverizing and all the other remaining components successively, disperse after 30 minutes, raise speed to 1500 revs/min again, continue dispersion until fineness is less than 60 μm and get final product.
The invention has the beneficial effects as follows: present component reasonable ratio, the manufacturing process of employing science, first the fillers such as scrap glass fiber, clay are carried out surface active, then add appropriate sodium bicarbonate and carry out granulation, pulverize after final high temperature sintering, the Activation filling made has loose porous feature, has certain sound-absorbing and the effect of insulation, there is good surface tension simultaneously, make to be uniformly dispersed in coating.
The present invention adopts elastomeric propylene yogurt liquid as film forming binder, coordinates the interpolation of emulsified bitumen, enhances binding property and water-repellancy; Add scrap glass fiber, clay, the rectorite leng after process, change surface tension, can better mix with emulsion, the coating made is coated with film elasticity, and good endurance, water-proof stain-resistant is good, not easy to crack.
