Environmentally friendly and heat-insulating building insulation materials

Abstract

The invention discloses an environment-friendly heat-insulation type building heat-preservation material. The environment-friendly heat-insulation type building heat-preservation material comprises aphenolic foam resin inner plate, a filling core and a phenolic foam resin outer plate, and the phenolic foam resin inner plate comprises a first plate body and a second plate body which are mutually buckled; the edge of the first plate body is provided with a flanging structure, and the edge of the second plate body is provided with an outward-extending connecting face; a plurality of supporting arrises are arranged on the surfaces of the opposites sides of the first plate body and the second plate body; the multiple supporting arrises are different in length; the first ends of the supportingarrises are flush with the edge of the first plate body or the second plate body, the second ends of the supporting arrises extend towards the longitudinal direction of the first plate body or the second plate body, every two adjacent supporting arrises are staggered and parallel; in addition, the supporting arrises of the first plate body and the second plate body are arranged in a staggered mode; and the filling core is mixed slurry filled in an inner plate body; and the exterior of the inner plate body is wrapped with the phenolic foam resin outer plate. Through matching of the inner platebody, the filling core and the outer plate body, the prepared heat-preservation material is small in weight, high in strength and excellent in fireproof and heat-preservation performance, and meanwhile, the utilization rate of bagasse is increased.

Description

technical field [0001] The invention relates to the technical field of building thermal insulation materials, in particular to an environmentally friendly and heat-insulating building thermal insulation material. Background technique [0002] Building insulation materials include extruded polystyrene foam glass, foam concrete (foam mortar), chemically foamed cement board, polystyrene particle insulation mortar, mineral wool (rock wool), phenolic resin board, expanded perlite insulation mortar Intel inorganic active wall thermal insulation materials, etc. Mainly by taking measures on the building envelope to reduce the indoor heat of the building to the outside, so as to maintain the building's indoor temperature. [0003] Phenolic foam material is a polymer organic rigid aluminum foil foam product, which is foamed from thermosetting phenolic resin. -196~+200℃) does not shrink or become brittle in low temperature environment. It is an ideal heat insulation material for HVAC...

Problems solved by technology

[0004] my country is a big planting country of sugarcane, and sugarcane will produce a lot of bagasse after sugar making, juicing or chewing. Previously, bagasse was generally discarded or burned as fuel, so the utilization rate of bagasse is very low. It is used in the extraction of alcohol and the preparation of paper, etc., but the utilization rate still needs to be further improved, and the technology is not very mature. Secondly, bagasse has a small specific gravity and good fiber quality. It is used to make boards with high strength and light weight. The board produced is free from biological attack, has low water absorption, is not corroded by seawater, and has obvious advantages in fire resistance and good flame retardancy. Therefore, if it can be applied to the production of building insulation and fireproof materials, it will not only solve the problem of Pollution discharge of agricultural waste and urban waste, also avoiding the waste of bagasse, and reducing the production cost of insulation materials
