Abstract
The present invention relates to a novel underwater paint manufacturing method. 60 shares of water are added to a reaction kettle and heated up to 60 DEG C; 20 shares of polyvinyl alcohol are added, stirred and heated up to 85 DEG C until all material is dissolved; the reaction kettle is cooled to 60 DEG C; 10 shares of formaldehyde solution are stirred into the reaction kettle to react for one hour with keeping temperature in 60 DEG C; after the reaction is completely stopped, the temperature is lowered to 50 DEG C; 0.5 share of sodium hydroxide solution are added to the reaction kettle to adjust PH value into alkalescence; then proper urea is added; 40 shares of calcite powder are added to a container with a stirrer, heated for dryness fully; the temperature is controlled with in 100 DEG C around; 8 shares of paraffin are crushed, added to the container, sealed, and heated up to 350 DEG C with stirring; powder material is packed by paraffin gasification; mixing and stirring are in according to share ratio of 1:3. The present invention has the advantages of simple construction, low cost, innocuity, tastelessness, no environmental pollution and long life-span.
Description
Technical field
The present invention relates to a kind of method for preparing novel waterproofing paint.
Background technology
At present, water-proofing powder can be scraped to such an extent that fly upward everywhere in construction, contaminate environment, and bedding cement is wanted in the influence construction on the waterproof bisque, the building cost height, range of application is narrow.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective, a kind of method for preparing novel waterproofing paint is provided.
Technical scheme of the present invention is: a kind of method for preparing novel waterproofing paint, it is characterized in that: by forming, polyvinyl alcohol and calcite in powder, cured portion rate are 1: 3, with calcite in powder and curedly weigh up by 50: 1 portion rates, earlier calcite in powder is added the container internal heating of belt stirrer, make the calcite in powder complete drying, add pulverize cured again, under air-proof condition, be warming up to 350 ℃ while stirring, make cured gasification parcel powder.
The present invention has the following advantages: easy construction; Reduce cost; Nontoxic, tasteless, non-environmental-pollution, long service life.
Embodiment
Embodiment: a kind of method for preparing novel waterproofing paint, 60 parts of water are added reactors be heated to 60 ℃, under agitation slowly add 20 parts of polyvinyl alcohol, warming while stirring to 85 ℃ all stops heating after the dissolving to polyvinyl alcohol; Reactor is cooled to 60 ℃, continues stirring and slowly add 10 parts of formaldehyde solutions, keep 60 ℃, stir reaction down 1 hour, after question response stops fully, be cooled to 50 ℃; In still, add 0.5 part of sodium hydroxide solution and transfer to pH value alkalescence; Add an amount of urea again; 0.5 part of its preparation method of 20 parts of paraffin waxes of calcite in powder is: with 40 parts of containers that add belt stirrer of calcite in powder, heating is controlled at about 100 ℃ calcite in powder complete drying, temperature; Will 8 parts paraffin waxes pulverize the back and add in the containers, sealing, warming while stirring to 350 ℃ makes cured gasification parcel powder, gets final product; Mix by 1: 3 portion rate, stir.
