Abstract
The utility model relates to a composite floor made of non-formaldehyde base material, which adopts an integral structure of four layers, wherein a surface layer is a wear-resistant layer, a second floor is a decorative layer, a third layer is a base material layer and the bottom layer is a balancing layer. The base material layer adopts a straw high density fiberboard, and the density of the straw high density fiberboard is equal to or more than 0.80 g/cm<3>. Melamine adhesive without formaldehyde for impregnation stick the four layers into a whole. The utility model has the advantages that because the base material layer is made of non-formaldehyde isocyanate as adhesive so as to reduce the release amount of the formaldehyde of the base material layer (equal to or more than 0.05 mg/L), which causes the material of a floor body to release non-formaldehyde, therefore the utility model achieves the goal that integral material for laying the ground has a low release amount of the formaldehyde. The suitable non-formaldehyde adhesive can satisfy the gluing of the surface wear-resistant layer, the bottom balancing layer and the base material layer. The utility model can widely be used in places where the limit of the release amount of the formaldehyde is high, such as hospitals, kindergartens, schools, sanatoriums, old people apartments, etc.
Description
Technical field
The utility model relates to the composite floor board that the formaldehydeless base material of a kind of usefulness is made, especially have the floor of low free formaldehyde release.Belong to interior decoration pavement technical field.
Background technology
At present, well-known pavement---the consolidated floor structure is made up of wearing layer, decorative layer, base material, balance layer.What be called as base material is to be the high density fiberboard that raw material is made with timber in fact, and it is the main body of consolidated floor, and it plays a part load-bearing, damping.Because used bonding adhesive is the urea-formaldehyde resin adhesive that contains formaldehyde when producing high density fiberboard, therefore, make the floor when using as pavement, exist free formaldehyde to discharge the defective of polluting indoor environment.
Summary of the invention
The purpose of this utility model is to exist formaldehyde to discharge the defective of polluting in order to overcome existing consolidated floor, the composite floor board that the formaldehydeless base material of a kind of usefulness is made is proposed, the problem that this floor does not only exist formaldehyde to discharge, and static bending intensity 〉=40.0MPa, thickness swelling rate≤2.5%.Technical solution of the present utility model: its structure adopts four layers of overall structure, and the top layer is a wearing layer, and the second layer is that decorative layer, the 3rd layer are substrate layer, and bottom is a balance layer.Substrate layer adopts stalk high density fiberboard, the density 〉=0.80g/cm of stalk high density fiberboard
3Four interlayers are bonded into an integral body with the melamine bonding adhesive with four layers by the dipping that does not contain formaldehyde.Advantage of the present utility model: because the substrate layer material therefor is to be bonding adhesive with formaldehydeless isocyanates, thereby greatly reduce base material formaldehyde burst size (≤0.05mg/l) make the floor material of main part not have aldehyde to discharge, thereby reach the purpose of whole pavement low burst size of methanal.The problem that this floor does not only exist formaldehyde to discharge, and static bending intensity 〉=40.0MPa, thickness swelling rate≤2.5%.Suitable bonding adhesive can satisfy the gummed of surface layer abrasion-proof layer, bottom balance layer and substrate layer.This reality is new can be widely used in PARA FORMALDEHYDE PRILLS(91,95) burst sizes such as hospital, kindergarten, school, sanatorium, the house for the elderly demanding place of limiting the quantity of with type.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Among the figure 1 is wearing layer, the 2nd, decorative layer, the 3rd, substrate layer, the 4th, balance layer.
The specific embodiment
The contrast accompanying drawing, its structure adopts four layers of overall structure, and the top layer is a wearing layer 1, and the second layer is that decorative layer 2, the 3rd layer are substrate layer 3, and bottom is a balance layer 4, substrate layer 3 adopts stalk high density fiberboards, the density 〉=0.80g/cm of stalk high density fiberboard
3, four interlayers are bonded into an integral body with the melamine bonding adhesive with four layers by the dipping that does not contain formaldehyde.
Wearing layer 1 is 35～50g/m for containing the high-abrasive material quality
2Impregnated paper, play a part the protection floor; Decorative layer 2 can play the attractive, decorative effect for containing the melamine-impregnated facing paper; Substrate layer 3 is the main body on floor, plays a part load-bearing, damping; Balance layer is the monochromatic impregnated paper that contains melamine, plays protection against the tide, keeps the indeformable effect of base plate whole machine balancing.
