A kind of integral core material fireproof insulation door and manufacturing method

Abstract

The invention discloses a fire prevention and heat preservation door with an integrated core material and a manufacture method of the fire prevention and heat preservation door. The door comprises a door plate that is a closed space; a plurality of I-shaped anchoring parts are fixedly arranged inside the door plate; an injection hole provided with feeder heads in two sides is formed above the door plate; the closed space composed of the door plate is fully injected with inorganic fire prevention and heat preservation materials. The manufacture method includes the preparation of the door plate and is characterized in that the anchoring pats are fixed to the door plate, and ball silicon composite building heat preservation material is injected into the closed space composed of the door plate through the injection hole by the injection method. The fire prevention and heat preservation door with the integrated core material and the manufacture method have the advantages that the integrated core used enables the problem of cold bridge of a split type core material to be solved and also brings a good heat preservation effect; in addition, the inorganic ball silicon composite building heat preservation material is adopted, any combustible material is not used, so that the fireproof effect is great; the anchoring parts enable the problem that the door plate is separated from the core material to be completely solved.

Description

technical field [0001] The invention relates to the field of construction, in particular to a fireproof and thermal insulation door. Background technique [0002] In the field of construction, fire doors have a wide range of demands. Existing fireproof and thermal insulation doors generally include a door panel and a core material. The door panel is closed, and the core material is a plurality of pieces, which are spliced ​​and arranged in the door panel, and are fixed with the door panel by bonding; this kind of fireproof and thermal insulation door is The core material is split spliced, therefore, a cold bridge is generated at the spliced ​​place, and the heat preservation effect is not good. In order to solve this problem, Chinese Patent Application No. 201210355969.1 discloses a fireproof door leaf, "comprising a door leaf formed by connecting the door leaf outer panel and the door leaf inner panel and the inner filler filled in the door leaf, the door leaf outer panel ...

AI Technical Summary

Problems solved by technology

"The shortcomings of this patent are very obvious. 1. Due to the use of organic materials for the inner filling material, the fire performance is poor; 2. The fixing method of the door panel and the inner filling material still adopts the method of adhesion. After a period of use, the door panel and the inner filling material break away
