example 1

[0030] A kind of novel coating of the present invention is made up of following weight percentage components:

[0031] Base: Polyvinyl alcohol solution 50%

[0032] Hemp stalk powder: 30-45%

[0033] Additives: 3-5%

[0034] Other fillers: 5-15%

[0035] Wherein, the concentration of the polyvinyl alcohol solution is polyvinyl alcohol: water=1:9 (weight ratio); the hemp stalk core powder is the stalk core powder of industrial hemp crops obtained by mechanically pulverizing the powder with a particle size of 10-500 mesh; the auxiliary agent includes Dispersant, antifoaming agent, appropriate amount of pigment; other fillers are calcium carbonate and talcum powder, and calcium carbonate:talcum powder=10:1 (weight ratio).

example 2

[0037] A kind of novel coating of the present invention is made up of following weight percent components:

[0038] Base material: pure acrylic emulsion 20%

[0039] Water: 25%

[0040] Hemp Stalk Powder: 40%

[0041] Auxiliary:

[0042] Dispersant 1%

[0043] Thickener 1.2-2.5%

[0044] Coalescent 1%

[0045] Defoamer 0.5-1%

[0046] Other fillers: 10%

[0047] Among them, the hemp stalk core powder is a powder with a particle size of 10-500 mesh obtained by mechanically pulverizing the stalk core of industrial hemp crops; the dispersant is sodium hexametaphosphate; the thickener is hydroxymethyl cellulose; the film-forming aid is Alcohol ester-12; defoamer is NXZ (metal soap defoamer); other fillers are calcium carbonate and vertical ceramic powder, and calcium carbonate: vertical ceramic powder=3:1 (weight ratio).

example 3

[0049] A kind of novel coating of the present invention is made up of following weight percent components:

[0050] Binder:

[0051] Polyvinyl acetate emulsion 20%

[0052] Styrene Acrylic Emulsion 15%

[0053] Hemp Stalk Powder: 60%

[0054] Auxiliary:

[0055] Sodium hexametaphosphate 2%

[0056] Dibutyl phthalate 3%

[0057] Wherein, the hemp stalk core powder is a powder with a particle size of 10-500 mesh obtained by mechanically pulverizing the stalk core of industrial hemp crops.

Abstract

The invention discloses an environment protective paint, which comprises the following parts: base material, adjuvant and 80wt% industrial hemp rod core powder. The paint possesses absorbent, dampproof, fungal resistant, bacteriostatic effect, which is fit for kinds of wall decoration.

Description

technical field [0001] The invention relates to a coating preparation process, in particular to a modified multifunctional environmental protection coating filled with industrial hemp stalk core powder, which belongs to the technical field of coatings. Background technique [0002] At present, in order to reduce costs and increase efficacy, most decorative paints are added with a considerable amount of fillers. The research on this filler-filled modified coating has been the focus of research in the coatings industry in recent years, and has obtained a large number of patent authorizations. There are many filler particles used for coating modification, mainly including metal powders (such as Al, Ti, Cr, Co, Nd, etc.), metal oxides (such as SnO2, MgO, TiO2, ZnO, etc.) and various inorganic fillers (such as SiO2 , CaCO3, talcum powder, bentonite, lime, gypsum, lithopone, quartz powder, titanium dioxide, white cement, etc.). With the development of science and technology, esp...
