Abstract

The utility model relates to a fireproof composite extrusion molding thermal insulation plate which comprises a plate body, phenolic foam fireproof materials, an adhesion agent, a piece of alkali-resistant mesh cloth and anti-crack mortar. The phenolic foam fireproof materials are attached to four side faces of the plate body in a sealed mode to form a composite plate body, the adhesion agent coats the upper face of the composite plate body and the lower face of the composite plate body, the anti-crack mortar coats the adhesion agent, the alkali-resistant mesh cloth is paved in the anti-crack mortar, and the alkali-resistant mesh cloth, the anti-crack mortar and the phenolic foam fireproof materials on the composite plate body together form an armored fireproof layer. Due to the fact that the upper face of the plate and the lower face of the plate body are chemically processed through the adhesion agent, the adhesion effect is enhanced. Contraction deformation of the plate body can be overcome due to the armored layer which is formed by the alkali-resistant mesh cloth and the anti-crack mortar, and meanwhile processing cost and procedures of the plate body are saved. The fireproof composite extrusion molding thermal insulation plate has the advantages of being capable of avoiding contraction deformation, good in fireproof performance, thermal insulation performance and heat preservation performance, simple to process, and low in manufacturing cost.

Description

Fire prevention composite extrusion warming plate

Technical field

The utility model relates to a kind of composite extrusion heat insulating material, particularly a kind of fire prevention composite extrusion warming plate for the skin insulation.

Background technology

The generation of " 2.9 " CCTV big fire in 2009, fire such as " 11.15 " Shanghai big fire in 2010, huge material damage and casualties have been caused, lesson is painful, wherein the fireproof performance of external-wall heat-insulation material is not good is the one of the main reasons that causes the fire tragedy to take place, therefore national departments concerned is also made more strict heat insulating material fire-protection standard, requires that its fire-protection rating is minimum must not to be lower than the difficult combustion of B1 grade.Present widely used extruded sheet external-wall heat-insulation material is to be main material with the polystyrene, melts pressing method by extruding machine by heat and processes.Extruded sheet commonly used on the market has two kinds, a kind of is the extruded sheet that meets the difficult combustion of B1 level product standard, the fire retardant extrusion molding that is added about 10% by pure granules of polystyrene forms, cost is higher, also can pollute environment, along with the prolongation of service time, flame retardant effect reduces gradually, even lose flame retardant effect, use this extruded sheet to exist the hidden danger that building catches fire; Another kind is the extruded sheet that reclaimed materials such as the polystyrene that reclaims or MPS are produced, cost of production is low, but, owing in this reclaimed materials, adding fire retardant product is lighted easily, do not meet the fire-protection rating requirement, so, in order to make this extruded sheet reach the fireproof performance of the difficult combustion of B1, notification number CN202483014U, the utility model patent of the patent No. 201220098127.8 provides a kind of " high bonding anti-deformation is exempted from the anchoring extruded sheet ", be extruded sheet to be designed to chevron-notch and the side is fluted, coat cement mortar concrete shell at the plate body upper and lower surface then, again four sides are applied the fireproof interface layer, be characterized in to make extruded sheet and exempt from the anchoring characteristic except having high bonding anti-deformation also have the fireproof performance of the difficult combustion of B1 level.Yet still there is deficiency in foregoing invention, the one, and there is harmful shrinkage strain in concrete shell self; The 2nd, the fireproof interface layer fireproof performance that the side applies is not poor, and be easy to operate and make plate body thermal and insulating performance variation; The 3rd, the chevron-notch of plate body processing and groove have strengthened cost of production and have been difficult for processing for the thin extruded sheet below 4 centimetres.

The utility model content

The purpose of this utility model is to overcome disadvantages of background technology, and a kind of fire prevention composite extrusion warming plate that reliable cementability, good heat-insulation and heat-preservation is arranged and can simply process the extruded sheet of thickness below 4 centimetres is provided.

The technical solution of the utility model comprises plate body, phenol formaldehyde foam fire proofing material, interfacial agents, alkaline-resisting grid cloth, anticracking grout.Four sides that the phenol formaldehyde foam fire proofing material is sealed on plate body form compound plate body, interfacial agents is coated in the upper and lower faces of compound plate body, anticracking grout is coated on the interfacial agents, alkaline-resisting grid cloth is layered between the anticracking grout, and alkaline-resisting grid cloth, anticracking grout and phenol formaldehyde foam fire proofing material on the compound plate body form the armored fireproofing layer jointly.

The utility model therefore constituted by plate body be core, by phenol formaldehyde foam fire proofing material edge sealing, by the compound plastic extrusion heated board of alkaline-resisting grid cloth and the upper and lower coating of anticracking grout and sealing.Though plate body does not have chevron-notch and groove in the background technology, but because the plate body upper and lower surface is through the interfacial agents chemical treatment, strengthened adhesive effect, after having coated the armor of alkaline-resisting grid cloth and anticracking grout formation, can overcome the shrinkage strain of its plate body, saved the processing cost of chevron-notch and the groove of plate body simultaneously, and to the manufacturing procedure of chevron-notch cement injection mortar.Again owing to abandoned the way of the plate body side coating fireproof interface layer in the background technology, change at plate body side sealing phenol formaldehyde foam fire proofing material, on the plate body, following two sides coats the anticracking grout armor, make each piece fire prevention composite extrusion warming plate all become one independently with the fire prevention unit of fire barrier (the phenol formaldehyde foam fire proofing material is through being commonly used for the material of external wall fire barrier), the actual fire barrier that equals the fire code requirement setting of exterior wall heat-preserving system country has been arranged on each piece and has independently prevented fires on the composite extrusion warming plate, makes it reach the requirement of heat preservation construction material fire-protection standard.

Be used as the phenol formaldehyde foam fire proofing material of edge sealing, also can adopt the extruded sheet or the cement foamed warming plate that reach the above fire protection requirement of B1 level to replace, can make the utility model reach the fire prevention isolation effect of difficult combustion B1 level equally.

Therefore, the utlity model has not shrinkage strain, fire line is good, heat preservation and insulation is good, processing is simple, cost is low advantage.
