Description

A kind of thermal insulation insulating panel of polyphenyl glass fibre cement and manufacture craft thereof

Affiliated technical field

The present invention relates to a kind of building heat preservation heat-insulation composite material and manufacture craft thereof, especially a kind of thermal insulation insulating panel of polyphenyl glass fibre cement and manufacture craft thereof.

Background technology

Thermal insulation insulating panel of polyphenyl glass fibre cement, polyphenyl refers to polystyrene, and english abbreviation is EPS, and glass fibre cement refers to glass fiber reinforced cement, and english abbreviation is GRC.Therefore thermal insulation insulating panel of polyphenyl glass fibre cement is abbreviated as the EPS-GRC plate.Its application mainly comprises,

(1) the architectural technology of making the isolation layer employing of EPS

The conventional use is inverted construction method, makes the thermal insulation layer with EPS.Behind deck, leveling layer, waterproofing course completion acceptance, lay the EPS plate, on the SPS plate, build mortar or concrete again.

The weak point that this technology exists is:

1. it is not firm to combine with mortar or concrete pavement, and temperature difference effectiveness easily plays drum, delamination, yielding, the drawing crack of surface layer mortar or concrete.

2. can not directly reach the decorative effect of surface layer, refilling decorations increases building costs.

3. site construction is wet water effect, and the scene will be finished mortar or concretely be mixed and stirred, builds, vibrates, receives slurry, troweling, maintenance, and the machinery and the water effect meeting of manually wetting cause the damage of EPS.

(2) EPS cement mortar mixture

Mix with EPS particle and mortar or concrete,, make heat insulation mixing precast plate by mould molding.

The weak point that this technology exists is:

1. EPS particle and mortar or concrete are mixed in-rise, and EPS is too light, and when mixing and stirring, two are difficult to reach uniformity.Vibrate down at artificial or machinery, above the EPS particle floats over, the closely knit difference of granular cementation body and loose fragile, finishing effect is poor, difficult quality control.

2. owing to be mixture, make this product both reduce the heat insulation usefulness of EPS, weakened the intensity of mortar or coagulation body again, the two pins down mutually, and physical property can not be given full play to separately.

When 3. constructing, can not solve the cold and hot bridge that piece produces, during two monomer splicings, there are vertical straight joint in lower curtate and surface, and heat is by this seam radiation and reception and registration.

4. stiff mortar leveling is adopted in construction, can destroy waterproofing course.

Summary of the invention

Its purpose of the present invention just is a kind of thermal insulation insulating panel of polyphenyl glass fibre cement and manufacture craft thereof are provided, and has solved composite plate and has both possessed bottom thermal insulation effect, possesses the problem of the high-strength decorative of surface layer again.Characteristics with thermal insulation and high-strength facial ornament, and do not participate in any organic adhesive material, have the cold and hot bridge effectiveness of blocking-up, can realize batch production production, improved work efficiency greatly, again can fine control product quality.

The technical scheme that realizes above-mentioned purpose and take comprises that glass fiber reinforcement cement board GRC lower surface connects polystyrene board EPS, and described polystyrene board EPS middle part end face is provided with tenon and blind mortise.

Its manufacture craft comprises, makes polystyrene board EPS layer, uses the polystyrene resin particle, high temperature foaming in touching by steel, and making possesses the corresponding structure of falling the capsule of polystyrene board EPS layer, tenon structure in the punching block; Make composite bed, on polystyrene board EPS and face that glass fiber reinforcement cement board GRC contacts, be manufactured with the structure of falling the capsule, the cryptomere tripe is young greatly, with pre-mixed short glass fiber refinforced cement plate GRC, insert in the capsule, vibrate, compacting, leave standstill maintenance slightly, then polystyrene board EPS back-off is gone in the glass fiber reinforcement cement board GRC prefabricated mould of not initial set, the two under external force mould close, after the glass fiber reinforcement cement board GRC of glass fiber reinforcement cement board GRC in the capsule and surface layer of falling solidifies, do not go out Nang Kou because of capsule is young, thereby form the composite bed of firm interlock; Make glass fiber reinforcement cement board GRC surface layer, with alkaline-resisting glass and low alkali cement, sand, water, inorganic pigment, bright preparation proportioning, uniform mixing, put into figuratum mould, by vibrating, leave standstill slightly maintenance, before the initial set and polystyrene board EPS compound, polystyrene board EPS and glass fiber reinforcement cement board GRC in mould compound after, the horizontal positioned mould, impose external force weight, make the two in conjunction with firm, before the demoulding, maintenance in the environment of 5 ℃≤T≤50 ℃, the demoulding; After the demoulding, the treadle-operated tilt hammer for hulling rice sign indicating number is at 15～20 ℃, and maintenance in the environment of 95% relative humidity after a couple of days, can be dispatched from the factory.

Compared with prior art the present invention has the following advantages.

1) owing to adopted the compound structure design of EPS-GRC plate, though EPS-GRC is whole, do not pin down the other side mutually, thermal insulation and high-strength facial ornament obtain maximum performance on same material;

2) owing to adopted EPS and GRC to pass through special construction, the structure design that firmly combines, thereby do not participate in any organic adhesive material;

3) owing to adopted EPS that the rebate structure Design is partly arranged, thereby adjacent two monomers are tied cold and hot bridge effectiveness capable of blocking by tenon during construction;

4) EPS-GRC can finish by batch production production, with existing many loaded down with trivial details construction sequences, is simplified in the plant produced, has improved work efficiency greatly, again can fine control product quality.
