Abstract
The present invention relates to a preparation method for porcelain wall paint, which is mainly prepared by using water, polyvinyl alcohol, lime putty, dolomite powder, formalin, urea and color paste as main ingredients. The method is simple and easy, prepared paint has the advantages of low cost, stable ingredient combination, good use effect, moisture prevention, heat resistance and abrasion resistance.
Description
The present invention relates to a kind of porcelain-imitated coating and manufacture method thereof.
Coating is people's the most frequently used materials when the buildings indoor wall is fitted up, and the quality of its performance directly influences decorative effect, makes the coatings decoration of making good use of, not only bright and clean attractive in appearance, and rise moistureproof, heat-resisting, wear-resisting, otherwise, then moisture-sensitive, peeling, peel off, influence attractive in appearance, poor effect.Existing coating type is a lot, but the technician still constantly studies, manufactures experimently it, looks for better composition, combination, and performance is better to obtain, the better new coating of effect.
The object of the present invention is to provide a kind of coating and manufacture method thereof in moistureproof, heat-resisting, wear resisting property, better effects if.
The compound method of this coating is that water, polyvinyl alcohol, lime putty, ground dolomite, formalin, urea, mill base are main raw material; In process for preparation, use hydrochloric acid soln, caustic soda (NaoH) solution to regulate the potential of hydrogen of mixed liquid.Through elder generation water, polyvinyl alcohol, formalin, urea, mill base are mixed with glue, and then glue is mixed into coating with lime putty, ground dolomite.Wherein the weight ratio of each raw material is respectively: water: polyvinyl alcohol: formalin: urea=10: 0.95～1: 0.2～0.25: 0.95～1, and glue: lime putty: ground dolomite=1: 1: 4.
Its concrete process for preparation is as follows:
Be iron plate at a shell earlier; inner casing is an aluminium sheet; ectonexine be separated by 10～12 centimeters interlayers be equipped with water the pot in add entry in proportion; purity is 85～88% polyvinyl alcohol solid; be heated to 100 ℃ of temperature; after treating that polyvinyl alcohol all dissolves; with the hydrochloric acid soln of 30～35% concentration potential of hydrogen being transferred to pH value is about 2; add formalin more in proportion; stir; cease fire; after stopping treating 40～60 minutes; igniting makes temperature rise to 100 ℃ again, and with 40～60% concentration caustic soda solns potential of hydrogen being transferred to pH value earlier is about 9; add urea then in proportion; stir, at this moment, can add different mill bases on demand; the insulation of ceasing fire just obtained glue mixture in 3-6 hour; add lime putty at last in proportion; ground dolomite stirs, and obtains coating.
According to method of the present invention, operation is simple, processing ease, cost is low, and the coating that preparation is come out, each composition combinative stability, result of use is good, and smooth finish is strong, protection against the tide, solar heat protection, wear-resistant, detect through Guangxi architecture science studying and designing institute, by the coating that the inventive method makes, glossiness 8.5, hardness (Bu Shi) H:83, thermotolerance: baking was filmed in 48 hours under 80 ℃～100 ℃ temperature does not have cracking,, foaming, dry linting, wear loss 0.3 gram (increasing the weight of 1000g, revolution 2000 times)
Working of an invention:
Embodiment 1,100 kg of water are put into pot, promptly put 10 kilograms of the polyvinyl alcohol (Guangxi vinylon plant, model 17-99) of 85% purity, heating, 100 ℃ of temperature, after treating the polyvinyl alcohol dissolving slightly, the hydrochloric acid that adds 30% concentration while stirring is 2 until record pH value with the pH value test paper, just adds 2.5 kilograms of formalin solutions under condition of stirring; Ceasing fire is incubated, and leaves standstill the heating of lighting a fire once more 50 minutes; caustic soda (NaoH) solution with 40% concentration adds under stirring condition, is 9 to get final product until record pH value with the pH value test paper, adds 9.8 kilograms in urea then; stir, evenly, add a little beige mill base; stir; ceasing fire is incubated 4 hours, gets about 130 kilograms of glue mixture, at last 130 kilograms of lime putties and 520 kilograms of ground dolomites is added; stir, obtain meeting the beige coating of the object of the invention.
Claims (2)
1, a kind of porcelain-imitated coating, mainly comprise formaldehyde polyvinyl acetal water, lime putty and ground dolomite, it is characterized in that: during preparation formaldehyde polyvinyl acetal water, the weight ratio of used each raw material is a water: polyvinyl alcohol: formalin: urea=10: 0.95～1: 0.2～0.25: 0.95～1; When preparing this porcelain-imitated coating, glue: lime putty: ground dolomite=1: 1: 4.
2, a kind of compound method of porcelain-imitated coating, choosing water, polyvinyl alcohol, formalin, urea, lime putty, ground dolomite is main raw material, earlier polyvinyl alcohol is dissolved, with hydrochloric acid solution acid alkalinity being transferred to pH value is 2, add formalin, with sodium hydroxide solution solution acid alkalinity being transferred to pH value is 9, adds urea then, is mixed with glue; The weight ratio of each raw material of preparation glue is water: polyvinyl alcohol: formalin: urea=10: 0.95～1: 0.2～0.25: 0.95～1; Again glue is mixed into porcelain-imitated coating with lime putty with ground dolomite, the weight ratio of each composition is glue during preparation coating: lime putty: ground dolomite=1: 1: 4.
