Abstract
The invention relates to a fire-proof gypsum board which comprises components as follows: 20 parts of semi-hydrated gypsum powder, 5 parts of fly ash, 1 part of glass fibers, 2 parts of volcanic rock fibers, 5 parts of high-strength gypsum, 1 part of sodium sulfate, 15 parts of zirconium silicate, 2 parts of calcium carbonate, 4 parts of aluminum oxide clay, 7 parts of magnesium oxide, 6 parts of magnesium chloride and 1 part of epoxy resin. The fireproof function of the fire-resistant gypsum board can reach the national requirement standard, the connection strength of the whole gypsum board is greatly improved, the fire-proof performance of connection positions between boards is also improved, and the cost of the whole gypsum board is reduced.
Description
Technical field
The present invention relates to a kind of finishing material, especially a kind of refractory plasterboard.
Background technology
Thistle board because it is lightweight, be easy to construction and there is the features such as good fire performance, be widely used in the partition wall of buildings, furred ceiling etc.But owing to being subject to the intensity of Thistle board self, meeting the restriction of fiery stability and fire endurance, the application of Thistle board remains in larger limitation.Fiber bar is set up in gypsum board core, to improve the intensity of Thistle board, be technology conventional at present, but, the physical strength of plasterboard there is the structure of fiber bar due to prior art and lays irrational problem, so can not meet the requirement of many use occasions.Plasterboard core is when meeting high temperature, and dihydrate gypsum absorbs heat, and discharges crystal water, and destroy the molecular linkage connecting these 2 water moleculess, every kilogram of dihydrate gypsum needs the heat energy of 712KJ, and moisture evaporation simultaneously also needs heat energy.So gypsum core in a fire every kilogram consume heat be about 1256KJ.Thistle board also has another characteristic, namely gypsum core contained humidity is not before all discharging and evaporating, the plate surface temperature of the Thistle board be made up of dihydrate gypsum core can not more than 140 DEG C, and gypsum is meeting the water that discharges after fire and the water vapour changed into by water is nontoxic.Therefore, Thistle board is widely used in the partition wall, furred ceiling etc. of buildings.What require along with building firesafety improves constantly, fire performance for Thistle board requires more and more higher, and therefore, the technical development of refractory plasterboard is swift and violent, demand is day by day soaring, and fire performance has become one of important factor of Thistle board market competition.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of refractory plasterboard.
For solving the problems of the technologies described above, refractory plasterboard of the present invention, it comprises following integral part, semi-hydrated gypsum powder 20 parts, 5 parts, flyash, 1 part, glass fibre, volcanic rock fibre 2 parts, high strength gypsum 5 parts, 1 part, sodium sulfate, zirconium silicate 15 parts, 2 parts, calcium carbonate, alumina clay 4 parts, 7 parts, magnesium oxide, 6 parts, magnesium chloride.
Described plasterboard also comprises epoxy resin 1 part.
This fire-resistant gypsum panel fire-proof function also can reach national requirements standard, and the strength of joint of whole plasterboard will improve greatly, and the fire line of the junction between block and block also has lifting, and the cost reduction of whole fire-resistant gypsum panel.
