Abstract

The utility model relates to a composite building board, which takes phenolic foam plastic as a base layer and compounds at least two layers of other materials. Compared with conventional building boards and common foam plastic composite boards, the composite building board has the advantages of better performance in fire prevention, fire retardance, thermal insulation and energy conservation, larger density range, sound isolation and moisture protection, so the composite building board has favorable overall performance. Besides, the composite building board has the advantages of high performance parameter, wide application range, and high construction efficiency. The composite board can meet various needs such as the internal and external heat preservation of buildings, vehicles, ships and pipelines, fire-proof decoration, etc., and is a novel light building material.

Description

The phenolic foam composite plate

The utility model relates to a kind of construction material, especially a kind of phenolic foam composite plate.

Modern architecture is skyscraper particularly, require employed materials for wall and decorating and renovating material fire retardant performance excellence to reduce fire damage, heat insulation property is good with energy savings, and is in light weight to alleviate structural load and to be easy to construction, should have certain intensity simultaneously.But present employed this type of construction material, its combination property all can not be satisfactory.Traditional material such as cement plate etc., though fire protecting performance is good, intensity is higher, and weight is bigger, and efficiency of construction is low, and insulation, and soundproof effect is not good.Based on the composite of traditional fibre material, as rock wool fibers or fiberglass composite plate, though have fire protection flame retarding preferably, the thermal efficiency is not high, and water proofing property is poor, and its thermal and insulating performance is still waiting to improve; And now as construction material several foamed plastics commonly used, as polyurethane foam plastics, polystyrene foam plastics, Vestolit, very light in weight, heat insulating effect might as well, but because of operating temperature is lower, at high temperature easily softening, shrink even burning, and then the generation toxic gas, and be not suitable for the high occasion of fire protection requirement.

The purpose of this utility model is, it is good to design a kind of fire retardant performance, and heat preservation energy-saving efficient height has the novel light bluk recombination construction material of the excellent combination property of certain intensity.

The technical solution of the utility model is:

A kind of phenolic foam composite plate belongs to a kind of construction material, it is characterized in that: be basic unit with the phenolic foam, thereon, following two sides all is compounded with other material that is no less than one deck, and the material of its adjacent two layers is inequality.(see figure 1)

A kind of phenolic foam composite plate belongs to a kind of construction material, it is characterized in that: be basic unit with the phenolic foam, be compounded with and be no less than other material of two layers on its one side that the material of its adjacent two layers is inequality.(see figure 2)

The phenolic foam that basic unit adopted be a kind of be raw material with phenolic resins through foaming, solidify the novel fire-retardant foam plastics that form, have the operating temperature height, state variation is little under limiting temperature, heat conduction is low, and is in light weight and density range is big, characteristics such as avirulence.Be a kind of desirable light body fire prevention, insulation material.Shortcoming is that low density foam intensity is lower.The contrast of its Specifeca tion speeification and other several foamed plastics sees Table 1.

The purpose of compound other material in basic unit mainly is low for remedying phenolic foam intensity, flimsy shortcoming, increase the bulk strength of composite plate, employed material can be a steel plate, iron plate, aluminium foil, cement, gypsum, glass felt, flame-retardant textile, flame-retardant materials such as fire retardant papers, thereby make its intensity obtain in various degree raising, to be applicable to different needs; Can not contact between the surface or layer and layer of burning things which may cause a fire disaster or high temperature at it, also can use common fabric and paper to reduce cost.Next is to increase decorative effect, the composite that is printed on pattern can be compounded in the surface of phenolic foam basic unit or other composite bed when needing, to beautify indoor environment.According to instructions for use, composite bed can be attached to phenolic foam basic unit on, following two sides, also can only be attached to its one side.Between basic unit and the composite bed, bonding between composite bed and the composite bed with adhesive, perhaps realize the combination of different material layer with solidifying of material, for example cement and glass fabric combines.

Be elaborated below in conjunction with the embodiment that provides in the accompanying drawing.

Embodiment 1 among Fig. 3 is a kind of with compound with the basic unit again single face phenolic foam composite plate of two layers of glass fabric (3) folder one deck magnesia oxychloride cement (4), total 3-layer composite material.

Embodiment 2 among Fig. 4 be a kind of be the single face phenolic foam composite plate of composite with gypsum (5) and common paper (6) and fire-retardant calico paper (10), both increased intensity, have decorative effect again.

Embodiment 3 among Fig. 5 is that aluminium foil (7) is the two-sided phenolic foam composite plate of composite.

The embodiment 4 that provides among Fig. 6, two-sided is composite with cement plate (4) all.

Embodiment 5 among Fig. 7, one side is with steel plate (9), and another side is a composite with two layers of glass fabric (3) folder one deck magnesia oxychloride cements (4), has higher intensity.

In each accompanying drawing, all omit adhesive phase.

The utility model has following significant good effect: 1 fire retardant performance excellence is particularly useful for the commercial establishment of public gathering. 2 insulations, good energy-conserving effect can be society and saves mass energy. 3 very light in weight and reduce difficulty of construction and to the requirement of building structure, reduce building materials consumption. 4 its density and strength range are bigger, applied widely. 5 can satisfy ornamental requirement.
