Abstract

The utility model discloses a roof thermal insulation plate, which solves a dropping corner or residue problem when the present polystyrene foam particle thermal insulation plate are moved or paved. The roof thermal insulation plate is perfused with a protective layer outside the inner core, the protective layer includes combination of fly ash, quick lime, cement, organic silicone emulsion abhor agent, fibrous glass short fiber or combination of fly ash, organic silicone emulsion abhor agent, fibrous glass short fiber, magnesium oxide, saturated solution of magnesium chloride, active silicon powder and boron oxide. Because of a protective layer is perfused outside the inner core, the utility model increases the strength and has hydrophobicity, reduces the damage rate in the process of transportation and construction, has not absorb water and be moistened, which guarantees the fixed value of the thermal conductivity coefficient and makes the thermal insulation reach the best condition, is unease to be damaged and drop residue. The production is open storage, which does not effected by the rain and moisture, and ensures the performance of thermal insulation.

Description

Roofing thermal-insulating board

[technical field]

The utility model relates to a kind of roofing thermal-insulating board.

[background technology]

At present, be used for the use polystyrene foam grain plate of building roofing insulation and the warming plate of cementitious materials mix moulding on the market, water absorption rate height, moisture-sensitive, under dampness, coefficient of thermal conductivity increases, and carrying, pave arrisdefect in the process, falling slag, influences building site environment and civilized construction, and slightly make on this plate surface, and suction reduces heat insulation effect easily.

[summary of the invention]

The utility model has overcome the shortcoming of prior art, solved existing polystyrene foam grain warming plate in carrying, pave arrisdefect in the process, fall the problem of slag.

A kind of roofing thermal-insulating board of the utility model; at the inner core outer filling layer protective layer is arranged, topping is flyash and calcium lime powder, cement, organic silicon emulsion hydrophober, the combination of glass fiber short fiber or the combination of flyash and organic silicon emulsion hydrophober, glass fiber short fiber, magnesia, magnesium chloride saturated solution, active silica flour and boron oxide.

The utility model is because employing has layer protective layer at the inner core outer filling, and intensity improves and has hydrophobicity, and spoilage reduces in the carrying work progress; do not absorb water, do not make moist; guaranteed the definite value of its coefficient of thermal conductivity, made thermal insulation reach optimum state, not fragile, do not fall slag.This product is deposited in the open, is not made of salt, is not afraid of and makes moist, and has guaranteed that thermal and insulating performance does not reduce.

[description of drawings]

Fig. 1 is a structural representation of the present utility model.

[specific embodiment]

As shown in the figure; the utility model roofing thermal-insulating board; at inner core 1 outer filling layer protective layer 2 is arranged, topping 2 is flyash and calcium lime powder, cement, organic silicon emulsion hydrophober, the combination of glass fiber short fiber or the combination of flyash and organic silicon emulsion hydrophober, glass fiber short fiber, magnesia, magnesium chloride saturated solution, active silica flour and boron oxide.Inner core 1 is the combination of the combination of polystyrene foam grain and silver powder blowing agent, flyash, cement, organic silicon emulsion hydrophober or polystyrene foam grain and silver powder blowing agent, flyash, magnesia, magnesium chloride saturated solution, organic silicon emulsion hydrophober.

During making; to be ground into the cement and polystyrene vinylic foam particle of 10-15mm through the mortar mixer mix with cementitious matter; make block semiproduct earlier, treat that it has certain intensity after, insert combination again and touch in the tool; give its six perfusion topping slurries; slurries pour into cement and polystyrene vinylic foam particle gap, and are fine and close through the bumper vibrations, combine closely with cement and polystyrene vinylic foam particle board; behind the thick skelteon of one deck 2-3mm to be formed with hydrophobicity, demoulding.
