Thermal-insulating and fireproof sandwich plate adopting foaming cement as core veneer

Abstract

The invention relates to the technical field of research and production of building insulation materials, and discloses a thermal-insulating and fireproof sandwich plate adopting foaming cement as a core veneer. Wood chip fiber is used as a panel, the foaming cement is used as the core veneer, a wood-face foaming cement sandwich plate is formed by pressing adopting a cold pressing preparation technology, and the panel can provide a better protective effect for the foaming cement sandwich plate; the fireproof strength of the foaming cement core veneer is improved, the defects of low strength, easy cracking and slag separation, bad decorating property and the like are solved, and the edgewise compressive strength, the bending strength, the impact toughness and the other mechanical strength of the sandwich plate can be greatly improved; and the advantages of good machining property, inorganic thermal insulation material heat-insulating property, sound insulation property, good flame retardant property and the like can be achieved, and the thermal-insulating and fireproof sandwich plate adopting the foaming cement as the core veneer can be applied to the field of decorative sheets, internal parting walls, fireproof door cores, fireproof wallboard and the like of the industrial and civil constructions.

Description

technical field [0001] The invention belongs to the technical field of building thermal insulation materials, and in particular relates to a thermal insulation and fireproof sandwich panel with foamed cement as the core panel. Background technique [0002] The rapid development of the national economy has driven the continuous heating up of the building materials industry, and energy and the environment are [0003] Two issues that have attracted increasing attention in the industry have gradually been put forward based on new requirements for building energy conservation and environmental protection. However, the overall architectural design is unreasonable, the energy-saving effect is poor, and it is not coordinated with a series of safety protection measures such as the environment and fire protection, which seriously affects the overall performance of the building, making energy conservation and environmental protection useless, and thus affecting the entire construction...

Problems solved by technology

[0004] Metal panels are easy to process and can be made into various shapes. Foam sandwich panels are mainly made of metal surfaces, which have disadvantages such as high energy consumption and poor recycling. Organic foam sandwich panels with wooden surfaces have good thermal insulation performance, but there are certain fire hazards. Inorganic non-metallic sandwich panels have disadvantages such as poor decoration and machining performance
