Description

Lightening gypsum suspended ceiling
Technical field:
The present invention relates to a kind of lightening gypsum suspended ceiling, belong to architectural decoration material field.
Background technology:
As everyone knows, the fire line of ceiling material, moistureproofness, heat retaining property are directly connected to the safe in utilization of buildings.And decorated gypsum board is with its good heat insulation property, fire line and be widely used.Though but at present decorated gypsum board is produced raw materials used terra alba water paste ratio and differed, goods unit weight generally all reaches 0.9-1.0g/cm 3Because product unit weight is bigger, not only increase the consumption of raw material and manpower, and can increase the deadweight of buildings, influenced the work-ing life of buildings to a certain extent, therefore in furred ceiling industry now, people favor in the ceiling material of " light, skilful, new " always.Now both at home and abroad generally adopt foaming or fill the unit weight that reduces plastering as light skeletal such as plastic foam particle, pearlstone or both bonded methods, the unit weight of the plastering of being produced can be reduced to 0.7-0.8g/cm 3, compare with original technology, its goods unit weight has had reduction to a certain degree, its reduction ratio is little, has the inaesthetic problem of product appearance simultaneously, though have adopted secondary forming process, but technological operation is complicated, so be subjected to certain restriction on using.
By literature search, do not see the open report identical with the present invention.
Summary of the invention:
The objective of the invention is to overcome the deficiency of prior art, and provide that a kind of product unit weight is low, intensity is high, fire line and water tolerance excellence, the lightening gypsum suspended ceiling that outward appearance is good.
Lightening gypsum suspended ceiling of the present invention, by plaster of Paris, lightweight filler, properties-correcting agent, water-resisting agent, glass fibre, and the aqueous solution that contains the 5-10% polyvinyl alcohol is prepared from; The weight percent of its component is: plaster of Paris 50-70%, light filler 8-15%, properties-correcting agent 0.5-1.5%, water-resisting agent 1-2%, all the other are the aqueous solution that contains the 5-10% polyvinyl alcohol.
Wherein:
Light filler is that a kind of in light calcium carbonate or Magnesium Carbonate Light 41-45 or the white carbon black or two kinds or three kinds mix by arbitrary proportion and use;
The components by weight percent of properties-correcting agent is: add silicon sol 15-20 gram, Sodium Fluoride 5-7 gram, potassium aluminium sulfate 4-6 gram, potassium bichromate 7-9 gram, tributyl phosphate 0.5-1 gram in the water of water 100 grams;
Water-resisting agent is that main component is the waterproofing agent of organosilicon of methyl silicon sodium alcoholate or methyl silanol potassium;
Glass fibre is low alkali or alkali free glass fibre.
The employing prior art for preparing of lightening gypsum suspended ceiling of the present invention, its step is as follows:
(1) preparation of properties-correcting agent: add silicon sol, Sodium Fluoride, potassium aluminium sulfate, potassium bichromate, the mixing of tributyl phosphate raw material in the water of 100 grams, stirring was left standstill 2-3 hour after making its dissolving;
(2) add plaster of Paris, light filler, properties-correcting agent, water-resisting agent, glass fibre in the aqueous solution that contains the 5-10% polyvinyl alcohol, the formation gypsum slurry stirs;
(3) gypsum slurry for preparing is poured in the mould, with iron plate that it is applied, through vibration, floating, close its natural aquation of cover mold operation relief;
(4) treat its final set after, with scraper four limits are wipeed off, remove cover mold, plasterboard is deviate from from mould;
(5) plasterboard after the demoulding is after placing 12 hours on the mounting table, allows its seasoning on hack;
(6) dried plasterboard is polished finishing, and the spraying emulsion paint carries out surface treatment;
(7) sending into temperature is that the oven dry of carrying out 2-3 hour in 40-50 ℃ the drying room promptly obtains lightening gypsum suspended ceiling.
Removing properties-correcting agent among the present invention is autogamy, and all the other are the commercially available prod.
It is low that lightening gypsum suspended ceiling of the present invention has unit weight, the intensity height, and fire line and water tolerance excellence, advantage such as technological operation is simple can be widely used in the top ceiling furred ceiling.
