Abstract

The invention relates to a granite insulating-fireproof composite board and a production method thereof, belonging to the field of building decoration and mainly solving the fireproof problem of the conventional composite board. The invention adopts the main technical scheme that 1) six-surface sealing treatment is carried out on an insulating material (polyurethane); 2) a noncombustible material is used as a sealing material, wherein five surfaces are made of cement fiber boards, and one surface is made of granite veneers; 3) the sealing material has the following performance indexes: the tensile strength is not less than 0.15MPa, and the water absorption is not more than 8%; 4) the insulating material (polyurethane) is arranged in a cavity, and is bonded with the sealing material in a high-strength manner by high-pressure foaming; and 5) a proper amount of a fire retardant is put into the insulating material (polyurethane), so that the insulating effect is not influenced and the fireproof performance is improved simultaneously. The invention has the main purposes of being used for building decoration and curtain wall engineering, having three effects of decoration, insulation and fireproofing for building elevation, and being a great contribution for the building materials in China.

Description

Granite heat insulative fire-proof composite plate and production method thereof

Technical field: the present invention belongs to the building decoration technology field, mainly solves the technical problem of fire prevention aspect.

Background technology: the thermal insulating composite panel on the existing market, problem of ubiquity, that is exactly that the comprehensive fireproof performance of thermal insulating composite panel is low, has significant limitation, the requirement of the paces that have been out of step with the times, it is extremely urgent, imperative to solve this type of problem.

Summary of the invention: when improving the fireproof performance of heat insulating material own, adhesive strength, main is the fireproof performance that improves thermal insulating composite panel from structure.

Description of drawings: Fig. 1 is the A-A sectional drawing; Fig. 2 is the B-B sectional drawing; Fig. 3 is a schematic perspective view; Fig. 4 installs node diagram (cross-sectional); Fig. 5 installs node diagram (vertical profile).

The specific embodiment: the heat insulating material in the composite plate (polyurethane) is carried out six complete encapsulation process with incombustible material; Polyurethane is high-intensity bonding through high-pressure foam effect and encapsulant in die cavity; So just, form a new complete hermetically-sealed construction system, thereby improve its fireproof performance.

Claims

1. a granite heat insulative fire-proof composite plate structure is by forming like the lower part.

1) architectural surface.

2) insulation layer (intermediate layer).

3) five sealants (bottom and four sides sealant).

2. according to claim 1, it is characterized in that following several aspect.

1) architectural surface is a thin plate granite, thickness 9～18mm; Bulk density>=2.3g/cm ³

2) insulation layer adopts polyurethane to do raw material, its tensile strength>=0.12Mpa; Coefficient of thermal conductivity≤0.024W (mk).

3) material of five sealants is incombustible material (cement fibrolite plate) and processes its tensile strength>=0.15Mpa; Water absorption rate≤8%.

3. the production method of granite heat insulative fire-proof composite plate comprises following several steps.

1) decoration panel is placed on the mold cavity bottom.

2) the vertical encapsulant of placing around the wall of die cavity, die cavity top is with the encapsulant sealing and cover the mold pressing lid, so just forms complete hermetically-sealed construction system.

3) in mold cavity, inject liquid polyurethane, it is bonding through high-pressure foam and encapsulant.

4. according to claim 3, it is characterized in that following several aspect.

1) can be handling in view of this mould, decoration panel is not only conventional flat board, also sketch plate like lines, circular arc etc.

2) structure that seals fully can be from the great fireproof performance that improves thermal insulating composite panel on the structure.

3) polyurethane that adds fire retardant has improved fireproof performance again greatly when not influencing its heat-insulating property, high-pressure foam can make polyurethane and encapsulant high strength bonding.
