Description

Technical Field

[0001] The utility model relates to the field of extruded board production, in particular to a crack-resistant and moisture-proof extruded board. Background Art

[0002] Extruded board is a kind of thermal insulation board with stable performance and not easy to age. It can generally be used for more than 30 years. Extruded board is widely used in building exterior wall insulation, cold storage insulation and floor heating insulation industry.

[0003] Extruded board is made of polystyrene resin as raw material, with the addition of foaming agent, flame retardant and other chemical materials. After all the materials are mixed, they are put into the extruder. The extruder heats and plasticizes the materials under high temperature and high pressure. The extruded board with a prototype is then cooled and formed.

[0004] As for the existing extruded boards, the connection between the existing extruded boards is mostly fixed by related adhesives. However, during long-term use, the joints of this connection method will lose viscosity due to erosion by rainwater or long-term use, thereby destroying the structural strength of the extruded board joints. In addition, the current extruded boards are usually cast in an integral manner. If used for a long time in an ice storage or the exterior wall of a house, the extruded boards themselves are prone to corrosion. At this time, when impacted, the extruded boards themselves are prone to cracks. Therefore, an anti-cracking and moisture-proof extruded board is proposed to solve the above problems.

When subjected to large forces, the glass fiber layer will disperse a large amount of force, and the plate body will break, causing cracks in the first pores. After the polyurethane foam comes into contact with the polyol, a chemical reaction occurs, and it expands to fill the gap. When liquid penetrates, most of it is isolated by the waterproof cloth, and a small amount of moisture penetrates into the waterproof layer. The drying balls in the second pores in the waterproof layer absorb this part of the moisture, thereby improving the crack resistance and moisture resistance of the extruded board.

A plurality of fourth wedge blocks 3 are equidistantly and staggeredly arranged on the front and back sides of the plate body 1, and the fourth wedge block 3 on the front side is engaged with the fourth wedge block 3 on the back side.

[0032] Working principle: During manufacturing, the anti-cracking layer 4, the waterproof layer 5 and the thermal insulation layer 6 can be cast separately. The honeycomb support layer 601 opened in the middle of the thermal insulation layer 6 after casting can not only enhance the tensile strength of the extruded board, but also make the thermal insulation layer 6 in a vacuum state, which is not easily affected by the external temperature. The thermal insulation layer 6 is then fixed in the waterproof layer 5, and then slid into the second slot 402 of the anti-cracking layer 4 through the connecting block 501, and then injection molded and fixed.

When subjected to large force, the glass fiber layer 401 will disperse a large amount of force, and the plate body 1 will break, causing cracks in the first bubble 405. After the polyurethane foam 406 flows out and contacts with the polyol 404, a chemical reaction occurs, and it expands to fill the gap. When liquid penetrates, most of it is isolated by the waterproof cloth 504, and a small amount of moisture penetrates into the waterproof layer 5. The drying balls 503 in the second bubble 502 in the waterproof layer 5 absorb this part of the moisture.
