Abstract
A fibre-reinforced plaster plate is made of ardealite (45-65 Kg), cement (10-35 Kg), paper pulp (3-7 Kg), glass fibre (0.5-1Kg) and asbestos (5-22 Kg), and features low cost, high strength and water-proofing nature, and low dry shrink percentage.
Description
The present invention relates to plasterboard, be a kind of be major ingredient with the phosphogypsum, be aided with the plasterboard that can gain in strength of fiber.
Plasterboard is widely used in building construction sites such as furred ceiling, partition wall, partition.All there is some deficiency in polytype plasterboard major part of widespread use now: it is high that water resistance is poor, intensity is low, contract with dry rate reaches cost greatly.Those skilled in the art study the prescription that can reduce cost always, and still, cost reduces the then corresponding intensity of bringing and hangs down problems such as reaching the water resistance difference.How to study a kind of cost that makes and reduce, the also prescription of corresponding raising of technical indicators such as the intensity of product and water resistance simultaneously is one of subject matter of always researching and solving of those skilled in the art.
The objective of the invention is: a kind of fiber reinforced gypsum board is provided, makes it have that cost is low, intensity is high, water resistance reaches advantages such as drying shrinkage is little well.
Component of the present invention and weight percentage ranges are: phosphogypsum 45-65 kilogram, cement 10-35 kilogram, paper pulp 3-7 kilogram, glass fibre 0.5-1 kilogram, asbestos 5-22 kilogram.The present invention's component and weight percentage ranges preferably is: phosphogypsum 30-50 kilogram, cement 15-30 kilogram, paper pulp 5-7 kilogram, glass fibre 0.5-1 kilogram, asbestos 12-20 kilogram.Component of the present invention and weight percent are: 60 kilograms of phosphogypsums, 15 kilograms of cement, 7 kilograms of paper pulp, 0.5 kilogram in glass fibre, 17.5 kilograms in asbestos.The better value of the present invention and weight percent is: 57 kilograms of phosphogypsums, 21 kilograms of cement, 5.5 kilograms of paper pulp, 1 kilogram in glass fibre, 15.5 kilograms in asbestos.The present invention's weight error of each component in process of production is a soil 1.Asbestos of the present invention can adopt the asbestos of different grades to mix and use, and for example: asbestos can adopt the asbestos of different grades to mix, and can be divided into level Four 5-8 kilogram, Pyatyi 7-12 kilogram.The concrete application of asbestos of the present invention can adopt three grades to mix or adopt level Four with level Four and Pyatyi is mixed, or three grades mixed with Pyatyi etc., with the raising product strength; Reduce product cost.For example: adopt 6 kilograms of level Four asbestos and 9.5 kilograms of Pyatyi asbestos to mix in the asbestos.The present invention keeps higher intensity, better waterproof can substitute for the selected component that tackles the major problem, its component to reduce product cost.Phosphogypsum is an industrial waste, adopt the phosphogypsum cost lower, but its surrogate, as: the performance of dihydrate gypsum all is better than phosphogypsum, yet cost is high relatively, adopts dihydrate gypsum to substitute phosphogypsum, can also not add exciting agent in prescription, because the exciting agent in the component of the present invention is a cement, the intensity of product is reduced so adopt dihydrate gypsum to substitute phosphogypsum.Paper pulp in the component of the present invention can adopt slurries such as former wood pulp and wood, paper mixing to substitute.Glass fibre in the component of the present invention can adopt other fiber such as vinylon to substitute.
The product that adopts component of the present invention to make is that 6 millimeters sheet materials are example with thickness, and its technical feature is as follows: project technical requirements breaking load is average 〉=167 vertically, minimum value 〉=150, laterally average 〉=
392, minimum value 〉=353 weight per unit area kg/m
2Mean value≤9.0, maximum value≤10.0 bulking factor %≤0.3 percent thermal shrinkage %≤1 visual appearance plate face is smooth, allows defectives such as wave groove, scuffing.

Making method of the present invention is:
According to component ratio of the present invention with glass fibre, asbestos and paper pulp, mix after loosening, add again and get final product after phosphogypsum and water cement mix, the storage slurry is copied and is got, and makes its moulding, stacking pressurization then, carry out maintenance, be warming up to 100 ℃, curing time is that drying is cut into product again about 12-15 hour.
Making method of the present invention has reduced production process significantly.
The product that adopts prescription of the present invention and method to make has advantages such as cost is low, intensity is high, water resistance is good, contract with dry rate is little.
