preparation example Construction

[0029] See attached figure 1 , a kind of preparation method of cement fence paint, comprises the following steps:

[0030] 1) Take acrylic emulsion, film-forming aid and thickener, stir and mix to form base material, set aside;

[0031] 2) Mixing, grinding and sieving pigments and fillers to form pigments and fillers for later use;

[0032]3) Take deionized water, dispersant and wetting agent, stir and mix to form an aqueous solution, and add the pigment and filler obtained in step 2) to the aqueous solution to form a color paste;

[0033] 4) Mix the base material obtained in step 1) with the color paste obtained in step 3), add anti-aging additives and leveling agents to it, and filter to obtain the product.

[0034] Further, in the aqueous solution described in step 3), 0.1-0.5 parts by weight of an antifoaming agent and 0.1-0.5 parts by weight of an antimold and fungicide are also added.

Embodiment 1

[0036] 1) Take 35 parts by weight of acrylic emulsion, 5 parts by weight of film-forming aid and 2 parts by weight of thickener, stir and mix to form a base material, and set aside; wherein, the thickener is an alkali-swellable thickener, and the acrylic emulsion is made of 40wt% of acrylic acid, 45wt% of butyl acrylate, 6wt% of deionized water, 5wt% of emulsifier, 2wt% of acrylamide and 2wt% of organic silicon monomer are polymerized.

[0037] 2) Take pigments and fillers, wherein the weight ratio of pigments and fillers is 1:2, after mixing, grinding, and sieving, the particles below 50 μm form pigments and fillers for subsequent use; wherein, the pigments are inorganic iron oxide pigments, and the fillers are kaolin .

[0038] 3) Take 20 parts by weight of deionized water, 2 parts by weight of dispersant and wetting agent, and 0.5 parts by weight of defoamer, stir and mix to form an aqueous solution, and add 20 parts by weight of pigments and fillers obtained in step 2) to ...

Embodiment 2

[0042] 1) Take 50 parts by weight of acrylic acid emulsion, 3 parts by weight of film-forming aid and 1 part by weight of thickener, stir and mix to form a base material, and set aside; wherein, the acrylic acid emulsion consists of 40 wt% of acrylic acid, 40 wt% of butyl acrylate, deionized It is prepared by polymerizing 10 wt% of water, 3.5 wt% of emulsifier, 3 wt% of acrylamide, 3 wt% of organic silicon monomer and 0.5 wt% of ammonium persulfate.

[0043] 2) Take pigments and fillers, mix, grind and sieve to form pigments and fillers, and set aside.

[0044] 3) Take 10 parts by weight of deionized water, 1 part by weight of dispersant and wetting agent, 0.3 parts by weight of defoamer, and 0.1 part by weight of antiseptic and bactericide, stir and mix to form an aqueous solution, and mix 30 parts by weight of the pigment and filler obtained in step 2) Parts are added to an aqueous solution to form a color paste.

[0045] 4) Mix the base material obtained in step 1) with th...

Abstract

The invention provides a coating for a cement fence and a preparation method thereof to overcome the problems of poor ultraviolet resistance and proneness to ageing of conventional cement fence coatings, belonging to the technical field of constructional materials. The coating comprises the following raw materials by weight: 35 to 50 parts of acrylic acid emulsion, 1 to 5 parts of a film forming auxiliary agent, 1 to 2 parts of a dispersing and wetting agent, 20 to 40 parts of a pigment filling material, 10 to 20 parts of deionized water, 3 to 5 parts of an aging-resistant auxiliary agent, 1 to 2 parts of a leveling agent and 1 to 2 parts of a thickening agent. The preparation method comprises the following steps: mixing the acrylic acid emulsion, the film forming auxiliary agent and the thickening agent so as to obtain a base material; preparing color paste from deionized water, the dispersing and wetting agent and the pigment filling material; mixing the base material with the color paste; adding the aging-resistant auxiliary agent and the leveling agent; and carrying out filtering so as to obtain the coating. Under synergism of the acrylic acid emulsion, the pigment filling material and the aging-resistant auxiliary agent, ultraviolet resistance and aging resistance of the coating are substantially improved, brightness of the surface of the cement fence is improved, and the integral aesthetic properties of a building are improved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a cement fence coating and a preparation method thereof. Background technique [0002] With many advantages such as low cost, good fire resistance, simple manufacture and practicality, cement buildings have become the main product of today's construction industry, which greatly meets the growing needs of modern people's production and life. From cement walls, cement columns to cement fences, all kinds of cement construction products are constantly emerging in front of us. Cement fences are also called cement art fences, cement guardrails, and cement railings. With the continuous advancement of the construction of new countryside and new cities, cement fences are fundamentally changing our production and living environments at a rapid rate. Local governments have successively issued environmental improvement policies such as demolition of walls to reveal greenery and v...
