Abstract
The utility model relates to the technical field of building materials, in particular to a thermal insulation composite plate capable of eliminating methanal. The composite plate is in an integrated structure and comprises a plant fiber layer, a rigid polyurethane foam composite layer and an epoxy resin layer in sequence from the top down, wherein the rigid polyurethane foam composite layer is a uniform composite layer of rigid polyurethane foam and activated charcoal powder. The activated charcoal powder uniformly distributed in the thermal insulation composite plate capable of eliminating the methanol has a larger contact area with the methanal, and can eliminate the indoor methanal effectively; the rigid polyurethane foam layer can realize a thermal insulation function; owing to the epoxy resin layer and the plant fiber layer, the composite plate can have certain longitudinal and transverse breaking strengths; and owing to the epoxy resin layer, the composite plate can be pasted on a building wall surface simply and rapidly.
Description
Technical field
The utility model relates to building material technical field, particularly a kind of thermal insulating composite panel of eliminating formaldehyde.
Background technology
Along with improving constantly of people's living standard, people are more and more higher to the environmental requirement in the room, the Formaldehyde in especially repairing the house for new clothes.Most people adopts ventilation, eliminates airborne formaldehyde indoor supporting except methods such as formaldehyde plants, and these methods are consuming time longer.Also have some users to come airborne formaldehyde in the decontamination chamber at the ornament of some active carbon charcoal bags of indoor placement or active carbon material, because these active carbons all are to be graininess or large bulk flocks together, so its adsorption time for formaldehyde is longer, active carbon is difficult to utilize fully substantially.
The utility model content
The technical problems to be solved in the utility model is: provide a kind of when can effectively eliminating formaldehyde, the composite plate of heat-insulating property can be provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of thermal insulating composite panel of eliminating formaldehyde, and this composite plate is the integral type structure, from top to bottom comprises successively: plant fiber layer, hard polyurethane foam composite bed, epoxy resin layer; The hard polyurethane foam composite bed is hard polyurethane foam and the even composite bed of powdered activated carbon.
Described hard polyurethane foam composite bed thickness is 1～2cm, and the surface density of active carbon is 8～12g/m
2
The thickness of described plant fiber layer is 0.2～0.3cm, and the thickness of epoxy resin layer is 0.3～0.4cm.
The length of described composite plate is 100mm～400mm, and width is 80mm～380mm.
Beneficial effect: equally distributed powdered activated carbon in the thermal insulating composite panel of eliminating formaldehyde of the present utility model, but the contact area of itself and formaldehyde is larger, can effectively eliminate indoor formaldehyde, and the rigid polyurethane alveolar layer can be realized heat insulation function; Epoxy resin layer and plant fiber layer can be so that composite plate have certain vertical and horizontal breaking strength; Epoxy resin layer also can make this composite plate be covered on simply, rapidly building wall.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified;
Fig. 1 is side structure schematic diagram of the present utility model;
Among the figure, 1. plant fiber layer, 2. hard polyurethane foam composite bed, 3. epoxy resin layer, 4. powdered activated carbon.
The specific embodiment
Below in conjunction with preferred embodiment the utility model is further specified.
Embodiment one
