Abstract
The utility model belongs to a building decoration plate. The utility model comprises an upper protection face, a lower protection face, and a gypsum layer clamped between the upper protection face and the lower protection face; small holes are respectively distributed on the upper protection face and the lower protection face. The protection faces and the gypsum layer form integration structure, and the protection faces adopt glass fiber mat. Thus, the protection faces of the gypsum plate have small shrinkage, the sticking fastness between the protection faces and the gypsum layer is strong, the decoration effect is good, and the service life of the utility model is long.
Description
The utility model belongs to a kind of building and ornament materials, particularly relates to a kind of gypsum plank.
Existing gypsum plank mainly is a Thistle board, is " light-weight refractory Thistle board " patent of 93202702 in the patent No. of on February 13rd, 1993 application as Beijing General Factory of New Building Materials.Because it is bigger that paper shrinks, and is easy to generate the crack, between paper and the gypsic horizon adhesion stress that sclerosis produces by gypsum, adhesive fastness paper peels off easily, and paper easily turns to be yellow, and influences application life.
The purpose of this utility model is to provide a kind of mask shrinkage little, the shrinkproof gypsum plank that mask and gypsic horizon adhesive fastness are strong.
The utility model is to realize by following technical scheme: shrinkproof gypsum plank, and comprise upper and lower mask and be clipped in gypsic horizon between the upper and lower mask, be covered with aperture on the upper and lower mask.
The upper and lower mask of gypsum plank is a glass fibre mat.Upper and lower mask by 2～8 layers of glass fibre mat constitute is covered with irregular aperture on it.
Be covered with aperture on the upper and lower mask of the present utility model, gypsum can see through aperture upper and lower mask and gypsic horizon are combined into one, and adopts glass fibre mat as upper and lower mask in addition, and the mask shrinkage is little, adhesive fastness is strong between mask and the gypsic horizon, can not produce the mask crack.Glass fibre mat is difficult for jaundice, keeps the gypsum true qualities, is convenient to finishing and long service life.
Fig. 1 is shrinkproof gypsum plank cross section structure schematic diagram.1,3 are respectively mask up and down among the figure, and 2 is gypsic horizon, and 4 is aperture.
Embodiment:
Shrinkproof gypsum plank by last mask 1, down mask 3 and be clipped in mask 1 and following mask 3 between gypsic horizon 2 constitute, upper and lower mask 1,3 constitutes by 5 layers of glass fibre mat.Be covered with irregular aperture 4 on the upper and lower mask 1,3 of gypsum plank.9.5 millimeters of gypsum thicknesss of slab, wherein gypsic horizon is 2 thick 8.5 millimeters, and upper and lower mask 1,3 is thick to be respectively 0.5 millimeter.
