Abstract
The present invention discloses a method of making ligth wt. wall material, used here are: polyvinyl alcohol, magnesium chloride, sodium hexametaphosphate, ferrous sulfate, oxalic acid as chemical raw material to prepare mother liquor, then mix and stir said mother liquid with magnesium oxide, plant fiber, fibrous glass to obtain slurry which is poured into mould, after extracting, pressing, smear planing, natural solidifying, demould to obtain the light wall material. Advantages: simple and reliable method, non-toxic and odourless product, heat insulation, sound insulation, easy processing etc.
Description
The present invention relates to a kind of material of construction.It can be used as the interior wall of frame structure building and steel construction, so and the decorative exterior wall of buildings.
In recent years in building trade,, build a house, increase acreage under cultivation for solving the minimizing conventional clay along with deepening constantly of wall reform.It is that material is produced the internal partition for building plate that people extensively adopt Inorganic Chemicals such as magnesite and vegetable fibre.Although this inner partition plate can be saved the soil, and can saw, can dig, can follow closely, again can be shockproof, anticracking, heat insulation, sound insulation, and also construction is also very convenient.This inner partition plate ubiquity impervious poor, get damp easily, hygroscopic deformation is big.Because this three big defective makes existing inner partition plate be difficult to especially apply in top-grade building in construction industry.Milky Way Building Materials Factory in Chengdu is for solving the phenomenon of getting damp of inner partition plate for this reason, adopted hydrolysis method---partition plate behind the shaping and drying is placed in the pond that fills caustic soda and Eusol soaks 1---2 days.Though this immersion has solved the problem of getting damp, but it has destroyed the one-piece construction of product, and product strength can slowly be degenerated, and the life-span also can shorten greatly.Therefore impervious poor, get damp, hygroscopic deformation become and had the Three Difficult Issues that light cellular partition board presses for solution now.
That purpose of the present invention just provides is a kind of both nontoxic, tasteless, waterproof, heat insulation, sound insulation, can saw, can dig, can cut a hole, Pasting, construction is convenient again, and permeability resistance is good, does not get damp, indeformable in cold and hot dry wet alternating environment, the light-weight wall material of rake angle not.
The objective of the invention is to reach by following measure: it made mother liquor by polyvinyl alcohol, magnesium chloride, tertiary sodium phosphate, Sodium hexametaphosphate 99, Tai-Ace S 150, ferrous sulfate, oxalic acid, hydrochloric acid before this, and then was mixed with magnesium oxide, vegetable fibre, glass silk by this mother liquor and to make slip after stirring.After again slip being injected mould,, obtain required light-weight wall material at last through proposing slurry, compacting, floating, spontaneous curing, the demoulding.Wherein the prescription of mother liquor is by weight: polyvinyl alcohol liquid is that 46-50%, magnesium chloride are that 45-49%, Sodium hexametaphosphate 99 are that 0.8-1.2%, Tai-Ace S 150 are that 1.6-2.2%, ferrous sulfate are that 0.45-0.55%, tertiary sodium phosphate are that 0.8-1.2%, oxalic acid are that 0.45-0.55%, hydrochloric acid are an amount of.The prescription of slip is by weight: mother liquor is that 44-48%, magnesium oxide are that 40-42%, vegetable fibre are that 10-12.5%, glass silk are 1.5-1.65%.
The present invention is in mother liquor making processes, and the pH value of its mother liquor is 1---and 2.The degree Beaume of its mother liquor is 21-23 °.
The invention will be further described below in conjunction with embodiment: at first make mother liquor, getting tap water 100kg injects in the retort, put into 2.5kg polyvinyl alcohol solid again, the reacting by heating jar allows water temperature reach 70-80 ℃ then, and after constantly stirring treats that polyvinyl alcohol dissolves fully, when being cooled to 50 ℃ of left and right sides, drop into magnesium chloride 100kg more sequentially respectively, tertiary sodium phosphate 1kg, Sodium hexametaphosphate 99 1kg, Tai-Ace S 150 2kg (first water dissolves), ferrous sulfate 0.5kg, oxalic acid 0.5kg (first water dissolves), stir then about 1 hour, regulate the pH value of this solution to 1-2 with hydrochloric acid again.And regulate the degree Beaume of this solution to 21-23 ° by adding water or adding magnesium chloride.Last restir about 10 minutes mother liquor.Then get the mother liquor 100kg that makes and inject in the agitator, add magnesium oxide 80-100kg then, vegetable fibre 20-30kg, glass silk 3.5kg stirs fully, and stirring is slip.Also can in the slip that 100kg stirs, add the 5kg water-resisting agent in addition.At last slip is injected in the required mould, again through propose slurry, compacting, floating, spontaneous curing, the demoulding, cleaning is the light-weight wall material of being invented.
The present invention has following advantage: this light-weight wall material not only preparation method is simple, its product is nontoxic, tasteless, Waterproof, solar heat protection, sound insulation, can saw, can dig, can cut a hole, Pasting, and this product impermeability is fine, does not get damp, Indeformable in cold and hot dry wet alternating environment, rake angle not remains the flatness of this product, its product longevity Order consistent service life with concrete.
Claims (2)
1, a kind ofly produces slip by mother liquor and magnesium oxide, vegetable fibre, glass silk, again slip is injected mould, through putting forward the method that light-weight wall material is made in slurry, compacting, floating, spontaneous curing, the demoulding, it is characterized in that the prescription of mother liquor is by weight: polyvinyl alcohol liquid is that 46-50%, magnesium chloride are that 45-49%, Sodium hexametaphosphate 99 are that 0.8-1.2%, Tai-Ace S 150 are that 1.6-2.2%, ferrous sulfate are that 0.45-0.55%, tertiary sodium phosphate are that 0.8-1.2%, oxalic acid are that 0.45-0.55%, hydrochloric acid are an amount of.The prescription of slip is by weight: mother liquor is that 44-48%, magnesium oxide are that 40-42%, vegetable fibre are that 10-12.5%, glass silk are 1.5-1.65%.
2, the method for making light-weight wall material according to claim 1 is characterized in that producing in the process at mother liquor, and the pH value of its mother liquor is 1-2, and the degree Beaume of its mother liquor is 21-23 °.
