Abstract
The invention relates to a process for making heat-insulating board in architecture thermal insulation system, which comprises using vitrified pearl, light calcium carbonate, dispersable rubber powder, polypropylene fiber, wood fibre, sodium carboxymethyl cellulose and water as raw material through agitating homogeneously, charging water, spraying water and stirring, compacting and loading into molds, pressurizing demoulding and drying.
Description
Technical field
The present invention relates to a kind of preparation method of heat-insulating board for building wall, belong to building material technical field.
Background technology
The heat insulation system of buildings exterior-protected structure commonly used adopts heat-insulating materials such as polystyrene foam plate, thermal insulation mortar, hard polyurethane foam and glass wool, rock wool more at present.It is 200410000789.7 Chinese patent application that name is called " high-strength fireproof vegetable fibre composite insulation boards is production method extremely ", application number, disclose component of a kind of fire resistant heat preserving plate and preparation method thereof, main heat-insulating material is a pearlstone.The shortcoming of this prior art is: 1, directly used sodium silicate aqueous solution and organosilicon moisture repellent in the prescription of prior art, these two kinds of raw materials all are very rare aqueous solution, mix the moisture that stirs the back compound with perlite etc. bigger, moulding drying and dehydrating phase temperature is afterwards had relatively high expectations, time of drying is also longer, has increased the cost of product.2, water glass and organosilicon moisture repellent all are the very high materials of alkalescence, make the alkalescence of product also very high, as the skin of building heat preserving system; the accumulation of salt in the surface soil easily makes moist; influence the attractive in appearance of wall face, simultaneously its outer field steel wire protection net is got rusty, make glass fiber net aging and lose enhancement.3, sodium silicate aqueous solution is as tackiness agent, and the water tolerance after the film forming is relatively poor, and deliquescence and infiltration easily influences the intensity and the weathering resistance of product.4, pearlstone is as main lagging material, because ore in sand form stone is in vaporized expanding, it is the grain pattern of perforate that the overflowing of crystal water makes perlite, very easily pulverize and form powder, intensity is very low, product strength is reduced, and absorb steam again easily, the heat-insulating property of product greatly reduces after the moisture absorption.5, in the whipping process of preparing product, because the very easily broken powder that forms of perlite, churning time can not be long, but churning time is too short, cause glue and the perlite can not thorough mixing again, have a considerable amount of perlites surface and fail fully to be wrapped up, thereby influence the intensity of product by glue, damaged easily and fracture.6, it is damaged that warming plate surface adhesion layer of glass net, single face glass fiber net can not guarantee fully that fracture does not appear in product, is uncertain because cause the external force of fracture.
A kind of novel heat-insulating material glass bead appears in recent years; has more excellent insulation heat-insulating property than pearlstone; its particle is irregular spherical; the outside effect owing to the fusion vitreous of particle forms a kind of vitrified shell; constitute the sealed hollow structure; thermal conductivity is lower, and intensity is higher, and in light weight is a kind of fine lightweight, fire resistant heat preserving, ageing-resistant, the low material that absorbs water.Based on glass bead, light calcium carbonate is a filler, and re-dispersible glue powder and fiber are auxiliary agent, can make that weight is lighter, heat-insulating property is better, and intensity is better than the novel heat insulation plate of other lagging material.
Summary of the invention
The objective of the invention is to propose warming plate in a kind of building heat preserving system and preparation method thereof; change the prescription of prior art; and existing novel heat-insulating material glass bead used among the present invention, reducing product cost, and improve the heat-insulating property and the intensity of product.
The preparation method of the warming plate in the building heat preserving system that the present invention proposes, wherein raw materials used weight percent is:
Glass bead 56～70
Light calcium carbonate 13～26
Re-dispersible glue powder 1.5～3
Polypropylene fibre 0.1～0.3
Wood fibre 0.1～0.3
Carboxymethyl cellulose 0.1～0.4
Water 10～20
Its preparation method comprises following each step:
(1) glass bead, light calcium carbonate are mixed in proportion, and stir;
(2) in proportion re-dispersible glue powder, polypropylene fibre, wood fibre and carboxymethyl cellulose are added in the said mixture successively, stir;
(3) the above-mentioned dry blend for preparing is added entry while stirring in proportion, stir through water spray, molding mass is the material that leather hard mixes;
(4) above-mentioned material is packed in the mould, pressurization 350～500KN, and keep-uped pressure the demoulding 5～10 seconds;
(5) under 50～80 ℃ temperature, dry 2～3 hours, obtain finished product.
The preparation method of the warming plate in the building heat preserving system that the present invention proposes, its advantage is:
1, tackiness agent of the present invention adopts the re-dispersible glue powder of ethylene-vinyl acetate copolymerization, the molecular chain of multipolymer is a reticulated structure, so the joint cement water glass of its strength ratio prior art is high and have water-proof function, makes product of the present invention have better water resistance and intensity.
2, the present invention with novel heat-insulating material glass bead as main insulation insulating material; because it has vitrified shell of sealing; do not absorb water, and its strength ratio pearlstone is high, makes product also can keep stable thermal conductivity in life-time service.
3, the diameter of the used polypropylene fibre of the present invention is 0.02 ± 0.005mm, and length is 6～12mm, and the anti-post intensity of its monofilament is up to 500MP, and this has just improved the intensity of product of the present invention greatly.Therefore used wood fibre has improved the draw knot force of product because fiber is a forked.
4, preparation method of the present invention; prepare dry blend earlier; the half-dried material of refabrication, several dry powder raw materials thorough mixing in preparation process, very even; nor can make the glass bead fragmentation; add the water spray after dry blend is made, the rubber powder in the dry blend just forms latex, is wrapped on the shell of glass bead; be easy to bonding each other, improved the intensity of this product.
