Multilayer composite vacuum heat-insulating plate

Abstract

The invention discloses a multilayer composite vacuum heat-insulating plate. The multilayer composite vacuum heat-insulating plate comprises a first heat-insulating plate main body and a second heat-insulating plate main body which are arranged in parallel with each other. Mounting plates are mounted at the top and the bottom of the side face of the side, close to the second heat-insulating platemain body, of the first heat-insulating plate main body correspondingly, and locking bolts are connected to the mounting plates in a threaded mode. One ends of supporting rods are connected to the tops and the bottoms of the locking bolts in a threaded mode correspondingly, and the second heat-insulating plate main body is fixedly mounted at the other ends, away from the locking bolts, of the supporting rods. A plurality of fixing blocks are mounted at the bottoms of the first heat-insulating plate main body and the second heat-insulating plate main body correspondingly, and mounting grooves are formed inside the fixing blocks. Pressing rods are fixedly mounted at the bottoms of the fixing blocks, pressing plates are fixedly mounted at the tops of the pressing rods, and one ends of springsare mounted in the middles of the tops of the pressing plates. Design is reasonable, conception is ingenious, the good heat-insulating effect is achieved through the multilayer composite design, andthe multilayer composite vacuum heat-insulating plate is suitable for being applied and popularized.

Description

technical field [0001] The invention relates to the technical field of heat insulation boards, in particular to a multilayer composite vacuum heat insulation board. Background technique [0002] The material of the vacuum insulation panel is composed of glass fiber material and high heat-resistant composite material, and does not contain harmful asbestos components. It has high mechanical and dielectric properties, good heat resistance and moisture resistance, and good processability. Low thermal conductivity, high temperature resistance up to 250 degrees (220 degrees, 300 degrees), high flatness, excellent bending strength at high temperatures. Used in plastic molds, injection molds, rubber injection molds, vulcanizing machines in the rubber industry, molding machines, hydraulic presses, shoe machines, machinery manufacturing, injection molding machines, hot runner systems, motors, silicone molds, magnesium, zinc, aluminum alloy die-casting, etc. mold.

Problems solved by technology

[0003] At present, in order to prevent sun and heat insulation in house construction, it is often necessary to use heat insulation boards. The heat insulation boards currently used are simple in structure, and most of them are single-layer. It is poor, and workers need to install it piece by piece during installation, which is troublesome to install and wastes a lot of time, and there is no good fixing device between the existing heat shields, which will easily cause looseness after long-term use and affect heat insulation The use of the board, for this we propose a multi-layer composite vacuum insulation board to solve this problem
