Abstract

The invention discloses water-based latex inner wall paint and a preparation method. The water-based latex inner wall paint is prepared from, by weight, material components A including 18.5 parts of methyl methacrylate, 22.8 parts of ethyl hexyl acrylate, 3 parts of emulgator, 0.2 part of initiator and 57.8 parts of deionized water, and material components B including 44.3 parts of nanometer calcium carbonate solutions, 27.5 parts of other pigment, 0.82 part of auxiliary A, 0.91 part of auxiliary B and 28 parts of auxiliary C. The water-based latex inner wall paint is suitable for being used as water-based latex inner wall paint brushed on inner walls of buildings, has the excellent advantages of being flat and smooth in paint film appearance, high in glossiness, adhesive force, hardness and flexibility and the like, and has the advantages of resisting abrasion, washing and brushing and pollution and the like.

Description

A kind of water based emulsion interior wall coating and preparation method

Technical field

The present invention relates to paint field, be specifically related to a kind of water based emulsion interior wall coating being applicable to inner wall of building and brushing, have paint film appearance flat smooth, glossiness is high, the good characteristics such as sticking power, hardness, snappiness are strong, and there is wear-resisting, the positively effect such as washability, anti-pollution.

Background technology

Latex coating is also known as emulsion paint, and it is scattered in water with the fines of 1.1 ~ 0.5um by synthetic resins to form emulsion, and be main film forming substance with emulsion, after adding suitable pigment, filler and subsidiary material, through what grind.Latex coating is a kind of building coating most popular, the most popular at present, is one of developing direction of building coating.Latex coating has elegance, pure and fresh decorative effect, nontoxic, tasteless environmental protection feature.Feature: 1, take water as dispersion medium, safe low stain, generally only contains the solubility promoter of less than 5%, and is hypotoxic; 2, easy construction, acute painting, roller coating, spraying, rear instrument easy to clean of having constructed; 3, latex coating good permeability, can construct at wet substrate surface, construct under being also very suitable for hygrothermal environment; 4, metal latex coating dilute with water, without fire hazard, is very suitable for the cross-operation of shipbuilding industry japanning and welding; 5, coating fast drying, allows recoat in 0.5 ~ 2h, greatly shortens construction period; 6, the solid of latex coating under working viscosity divides high, and primary coating is coated with thickness, improves operating efficiency; 7, the resin relative molecular mass of emulsion dispersion system is high, smears good weatherability, and has good mechanical property, alkali resistance and water tolerance.Good gloss and ornamental is had as building coating; Make metal latex coating and have general barrier propterty.8, the shortcoming of latex coating is that film formation at low temp is poor, generally need construct more than 10 DEG C; The false crisp flowing of coating, easy thickening, paint-flow and wet film levelling property poor; After water volatilization, viscosity rises rapidly, and film easily produces bubble and pin hole; The surface tension of water is large, and the wettability of coating to base material is poor.In painting and use procedure, strong mechanicals efforts, can destroy the stability of latex coating, makes coating flocculate and go bad.

Summary of the invention

The object of the present invention is to provide a kind of water based emulsion interior wall coating being applicable to inner wall of building and brushing, there is paint film appearance flat smooth, the good characteristics such as glossiness is high, and sticking power, hardness, snappiness are strong, and there is wear-resisting, the positively effect such as washability, anti-pollution.

Water based emulsion interior wall coating of the present invention is combined by material component A and material component B.

Present invention employs such technical scheme: in described water based emulsion interior wall coating, the material of material component A and weight proportion are respectively: methyl methacrylate 18.5 parts, Octyl acrylate 22.8 parts, emulsifying agent 3% part, initiator 0.2% part, deionized water 57.8 parts.

The material of material component B and weight proportion be respectively: 44.3 parts, nano-calcium carbonate slurries, other pigment 27.5 parts, auxiliary agent A 0.82 part, auxiliary agent B 0.91 part, auxiliary agent C28 part.

Emulsifying agent of the present invention can select alkylphenol polyoxyethylene.Initiator can select ammonium sulfate.Other pigment can select kaolin, talcum powder, barite.Auxiliary agent A can select dispersion agent.Auxiliary agent B can select multifunctional assistant, mould inhibitor, sterilant.Auxiliary agent C can select defoamer, thickening material.

The present invention is applicable to the water based emulsion interior wall coating that inner wall of building is brushed.

The good characteristics such as this product has paint film appearance flat smooth, and glossiness is high, and sticking power, hardness, snappiness are strong, and there is wear-resisting, the positively effect such as washability, anti-pollution, the high temperature of more than 100 DEG C can be resisted; Cost is lower.

Embodiment

Its preparation method is following steps:

Step one), whole emulsifying agent and aliquots of deionized water and 1/2 Octyl acrylate and 1/2 methyl methacrylate put into stirred reactor stir, carry out reacting and reaching kick off temperature;

Step 2), by step one) add half initiator and aliquots of deionized water in the material that obtains, carry out system reaction to the state of turning blue, and keep constant temperature at the polymerization temperature;

Step 3), in step 2) institute obtains in material and adds remaining all materials and aliquots of deionized water and proceed reaction, until polyreaction terminates, obtains material component A;

Step 4), add nano-calcium carbonate slurries in a reservoir, with 150r/min rotating speed stir after, add auxiliary agent A and carry out high-speed stirring with 700r/min;

Step 5), in step 4) obtain in material and add other pigment, after carrying out high-speed stirring with 700r/min, with 800 order net filtrations;

Step 6), in another container, add material component A, auxiliary agent B stirs with 250r/min;

Step 7), by step 6), step 5) gained material adds auxiliary agent C after fully stirring, and carries out viscosity, pH value regulates, filling after froth breaking, finished product.
