Embodiment Construction

[0024] Shown in accompanying drawing, 1_foam polyurethane sheet, 2_carbon powder, 3_interlayer, 4_conveyor belt, 5_mixed material layer, 6_non-woven fabric, 7_rubber-like elastic layer, 8_carbon powder layer, 9 _ water vapor, 10_ pressure wheel, 11_ mesh conveyor belt.

[0025] Foamed polyurethane is widely used in products such as bedding and furniture, and most of them are flexible foamed polyurethane, which is suitable as an elastic material for these products.

[0026] And because a large amount of waste materials and defective products are produced in the factory of producing above-mentioned flexible polyurethane foam, the carbonized polyurethane foam pad of the present invention adopts waste foam polyurethane, especially waste flexible polyurethane foam as raw material.

[0027] The specific process is to put the above-mentioned flexible polyurethane foam into a crusher and crush into flexible polyurethane foam sheets of 10-30 mm size.

[0028] Add charcoal powder 2 in ...

Abstract

PROBLEM TO BE SOLVED: To provide foamed polyurethane mat containing charcoal, which excels in elastic capability and enables efficient use of potency of bamboo charcoal powder or charcoal powder.

Description

technical field [0001] The invention relates to a foamed polyurethane sheet with layered overlapping structure, in particular to a charred foamed polyurethane pad and its production method. Background technique [0002] Japanese Patent Application No. 52-134407 discloses the technology of filling the mixed material of urethane sheet and carbon powder in air-permeable bag-shaped outer skin materials such as cloth to produce bedding. In this technology, the mixed material of urethane sheet and carbon powder in the outer skin material may be unevenly distributed, and the problem of leakage of carbon powder may also occur. Of course it is also impossible to cut and produce any product according to the required size. [0003] Japanese Patent Registration Utility Model No. 3045700 describes the technology of impregnating activated carbon powder in foamed polyurethane sheets, and then pasting soft mesh fiber materials on both sides to produce healthy bedding. This technology is p...
