Besides, said invented product is light in weight, possesses good water-proofing and fire-resisting property, and its cost is low.
Description
The invention belongs to the building element technical field, a kind of specifically spliced-type integrated prestressed inorganic composite straw board and manufacture method thereof that is applied to building partition wall, liner insulation, roofing.
At present, generally with material constructing structures such as clay brick or concrete hollow block, gypsum block, pearlite concretes, its shortcoming is that overall performance is poor to the partition wall of building, because the coefficient of expansion of various materials is different, yielding, produce the crack, and long construction period, speed is slow.Occurred in recent years making keel with timber, the partition wall of two sides composite gypsum board, because the different combinations preferably with the plasterboard material of timber, and the seam between the plasterboard also has certain difficulty, and this wall does not insulate against sound, and reality is a matter of regret.
The objective of the invention is to realize a kind ofly have lightweight, sound insulation, do not fire, inexpensive, intensity is high, particularly good integrity, short construction period, fireballing spliced-type integrated prestressed inorganic composite straw board, and the manufacture method that proposes to make this spliced-type integrated prestressed inorganic composite straw board.
The present invention is achieved like this.
1, the prescription of inorganic composite straw board:

Hydrogen peroxide 0.2-1% (weight)
Water soluble phenol resin (solid content 30-40%) 3-5% (weight)
Plant straw (rice straw, wheat straw, multitudinous slag, the numb straw of silk, length 5-100mm) 25-36% (weight)
2, the manufacture method of inorganic composite straw board (1) is got the raw materials ready
Plant straw (rice straw, wheat straw, multitudinous slag, the numb straw of silk etc. wherein one or more) is cut into 30% (weight) that accounts for that length is 5-20mm, and length is 40% (weight) that accounts for of 20-70mm, and length is 30% (weight) that accounts for of 70-100mm.
With calcination temperature is 800-850 ℃, and the moisture proof storage period is no more than trimestral magnesia (containing 85% above MgO) and crosses 80 mesh sieves, percent of pass 100%.
Magnesium chloride (purity more than 46%, potassium, sodium content＜3%) is dropped in the vat, add water and stir fully dissolving, reach Be24-27 ° and add phosphoric acid again and transfer pH value, left standstill deposition removing foreign material 24 hours to 2-4.
Selecting hydrogen peroxide is blowing agent, and consumption is decided as requested.
Selecting water soluble phenol resin is waterproof and reinforcing agent.
(2) manufacture method.
Above-mentioned getting the raw materials ready mixed by prescription input mixer, mould compression moulding is gone in vibrations, a sheet material wherein side is groove, and opposite side is a boss, and 2-5 through hole is set, spout then into the artificial maintenance of curing means pressurize, be warmed up to 75-85 ℃ with 1 hour,, cooled to 30-40 ℃ in 1 hour 55-65 ℃ of constant temperature 4 hours, the maintenance of demoulding later stage kept 48 hours 15-25 ℃ of environment temperature.
3, assembly unit and prestressing force expand and draw anchoring
According to the building partition wall, the liner insulation, the requirement in the use of roofing specification or size, with 2-10 piece inorganic composite straw board of the present invention at on-site consolidation again, assembling anchoring apparatus, anchoring is with having the 2-5 group, the anchoring apparatus is by plate washer, high tensile steel wire, the ground tackle seat, the three-chip type cone anchorage is formed, the high tensile steel wire plate washer of connecting successively, the through hole that inorganic composite straw board is provided with, the plate washer of opposite side, the ground tackle seat, the three-chip type cone anchorage, draw anchoring with special bloated pull tool (prestress engineering common tool) is bloated, be the insulation of spliced-type integrated prestressed inorganic composite straw board partition wall or liner, roofing element.
The invention has the advantages that overall performance is good, and is indeformable, do not produce the crack, speed of application is fast, the cycle is short, the prescription of sheet material is reasonable, the plant straw that can dissolve a large amount of, and technology is simple, and is easy to operate, artificial maintenance goods have improved production efficiency, save mould, all can produce throughout the year.The product lightweight, waterproof, fire prevention, good heat insulating, and cheap.
Concrete structure of the present invention and manufacture method are provided by Figure of description.
