Embodiment 1

[0042] Such as figure 1 As shown, the root nodule structure 2 with a small opening and a large concave is opened on both sides of the extruded board 1 . Such as figure 2 As shown, the shape of root nodule structure 2 is a large hemisphere, such as image 3 As shown, the shape of nodule structure 2 is a water drop, such as Figure 4 As shown, the nodule structure 2 is in the shape of a flask, such as Figure 5 As shown, the shape of nodule structure 2 is a deformed flask shape. Nodule structure 2 is a fusion pore structure after laser sintering.

[0043] In order to achieve better bonding strength, the root nodule structures 2 are evenly arranged on the surface of the extruded board 1, the distance between the root nodule structures 2 is 0.5 cm, and the depth is 0.15 cm.

Abstract

The invention discloses an extruded plate. A concave hole is formed in the surface of the extruded pate, and the extruded plate is characterized in that the concave hole is of the structure of a rootnodule with a small opening and a large internal concave portion. When the extruded plate is glued with a contact layer, an adhesive enters the root nodule structure, an embedded anchoring structure with the outside smaller than the inside is formed after the adhesive is hardened, the extruded sheet and the contact layer are in dot connection through the embedded anchoring structure, combination is firmer, and stress is more even; deformation and warping of the extruded sheet are effectively overcome, the bonding strength of the extruded sheet and the contact layer is improved, and meanwhile excellent heat insulation, fire prevention, tension resisting and pressure resisting ability, the higher construction efficiency and the like are achieved.

Description

(1) Technical field [0001] The invention relates to a building material, in particular to an extruded plastic plate. (2) Background technology [0002] Extruded board has excellent thermal insulation (thermal conductivity is only about 0.028W / M·K), excellent high-strength compression resistance (compressive strength reaches above 150-700KPa), excellent water-repellent and moisture-proof properties, and anti-aging It is widely used in building roof insulation, steel structure roof, building wall insulation, building floor moisturizing, square floor, ground frost heaving, etc. control, central air-conditioning ventilation ducts, etc. However, there are many problems in the use of ordinary extruded boards. For example, the joints between boards are easy to produce through seams, which are called cold strips in engineering, which makes it difficult for the overall thermal insulation performance to meet the standard, and it is difficult to reach B1 level flame retardant.
