Abstract
The present invention discloses a light high-strength hollow gypsum composite wallboard and its blending ratio and manufacturing process. It is made up by using hemihydrate gypsum powder as main raw material, mixing it with the auxiliary materials of silicate cement, drowned lime and additive and water uniformly to make them into mortar body, adopting hollow sandwich plate structure and placing bamboo bars and fibre filament in the sandwich plate structure, and then pouring three times, so that said invented product can be made up. Said hollow gypsum composite wallboard integrates the partition and decoration into one body, and its cost is low.
Description
The present invention relates to a kind of plastering wallboard, be specifically related to a kind of light high strength hollow gypsum composite wall plate.
Present domestic gypsum industry product mainly is the thin type gypseous decorating board as materials for wall, and it is a primary raw material with gypsum, cement, light filler, adds fibre and additive again to strengthen the intensity of product.Chinese patent application number is 91108531.9 to disclose a kind of " light gypsum fibre board and preparation method thereof ", it is a kind of new prescription and technology, produce a kind of intensity height, gypsum fiber sheet material that unit weight is little, this sheet material can be described as big progress as a kind of wall decorative material.But the said goods can only be a kind of decorative material among the materials for wall, must be obedient in surface of wall, can't use as a kind of partition board.
The objective of the invention is to be to provide a kind of can be as the gypsum sheet material of partition board, it can contain partition wall, decorate.
Light high strength hollow gypsum composite wall plate of the present invention is to be primary raw material with the plaster of Paris, mix auxiliary material such as portland cement, hydrated lime, additive and water in proportion and stir into slurry, adopt hollow clamping plate mode through three times the cast, in add bamboo reinforcement and fibre moulding, the demoulding then, air dry maintenance get final product.Its main compound method and technology are as follows:
A prescription: (by weight percentage)
Semi-hydrated gypsum 54-78%
Portland cement 10-15%
Hydrated lime 6-10%
Inserts 0.5-3% such as additive 0.5-5% husk, sawdust, expansion perlite
Glass fiber 2-3%
Bamboo reinforcement 3-10%
Wherein bamboo reinforcement is wide 0.5-1.5cm, thick long lath more than 0.5, and additive is that the alkaline sodium abietate aqueous solution of 70-80% polyvinyl alcohol water solution, 5-8% contract methylated cellulose aqueous solution and 10-15% is in the mixed uniformly mixed solution of 100: 2: 0.5 ratio.
The B manufacture craft
Package mould by required specification, the brushing release agent in die surface, add 1/3 slurry as cast for the first time, then evenly the spreading glass fiber, be pressed into the bamboo reinforcement of 1/2 amount, add 1/3 slurry again as cast for the second time, then again the spreading glass fiber, be pressed into 1/2 the amount bamboo reinforcement, add 1/3 slurry at last again as cast for the third time, get final product through vibration, receipts light, welding bell, the demoulding, airing, maintenance again.
Characteristics such as gypsum hollow combined wall board of the present invention has that unit weight is little, resistance to compression, anti-folding, flexural strength height, and have good heat insulation, sound insulation and humidity resistance.Cost of the present invention is low, and product is convenient to transportation and is installed.
Provide optimum formula ratio of the present invention below in conjunction with embodiment.
Embodiment 1, a kind of 2600 * 600 * 53mm
3The material proportion of (11 holes, external diameter 32mm) wallboard:

Glass fiber 2.5%
2500 * 10 * 5mm
3Bamboo reinforcement 5%
Embodiment 2, a kind of 2600 * 600 * 123mm
3The material per distribution ratio of (5 holes, external diameter 90mm) wallboard:
Semi-hydrated gypsum 60%
425# portland cement 10%
Hydrated lime 10%
Additive 4.5%
Perlite and sawdust 3.5%
Glass fiber 3.0%
2500 * 10 * 8mm
3Bamboo reinforcement 9%
