Embodiment Construction

[0014] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0015] Such as Figure 1~2 As shown, the present invention provides a kind of extruded board, comprises the calcium silicate layer 1 and foam layer 2 that are stacked and extruded into one, the thickness of foam layer 2 is 3~5cm, and the bonding of foam layer 2 and wall surface There are multiple grooves 3 on the surface, the depth of the grooves 3 is 2~4mm, the width is 5~6mm, the grooves 3 are arranged at equal distances, the distance between two adjacent grooves 3 is 8~12mm, the grooves 3 is a long zigzag shape, and the groove bottom of the groove 3 is a wrinkled surface or a wave surface.

[0016] Inspired by the above-mentioned ideal embodiment accordin...

Abstract

The invention provides an extruded sheet which comprises a calcium silicate layer and a foam layer which are stacked and extruded into a whole. The thickness of the foam layer is between 3cm and 5cm, and a plurality of grooves are opened on the gluing surface of the foam layer with the wall surface. According to the extruded sheet, the plurality of the grooves are opened on the surface of the foam layer, so that the tensile bond strength of the sheet with adhesives and coating mortar is increased, the wall surface gluing strength is enhanced, and a certain amount of internal stress is released evenly.

Description

technical field [0001] The invention relates to a building material, in particular to an extruded plastic plate. Background technique [0002] Extruded board is a rigid foamed plastic board made of polystyrene resin as raw material plus other raw and auxiliary materials and polymers, heated and mixed through a special process while injecting a catalyst, and then continuously extruded. Its scientific name is extruded polystyrene foam for heat insulation (XPS for short). XPS has a perfect closed-cell honeycomb structure. Corrosion, low thermal conductivity, high compression resistance, aging resistance (almost no aging decomposition phenomenon in normal use), long service life, low thermal conductivity and other excellent properties of energy-saving and environmentally friendly insulation materials, but the existing extruded board in the wall However, the surface of ordinary extruded board is smooth. When it is attached to the wall, the adhesion between the surface and the ad...
