Embodiment 1

[0102] Thermoplastic foamed polyurethane fiberboards were prepared as follows:

[0103] Preparation of A surface layer:

[0104]

[0105] Stir the above raw materials with a mixer for 5-10 minutes, then use a 10,000-horsepower machine (internal mixer) to heat at 140°C for 5-8 minutes, squeeze and mature, and then heat and knead at 150°C with a double-roller mill. The four-roller calender presses the tablet, the thickness is adjusted to about 0.30mm, embossed, cooled, and the coiling is about 250m per bundle. Finally, use a printing machine to print graphics and text to obtain the A surface layer.

[0106] Preparation of B middle sheet:

[0107]

[0108] Stir and mix the above raw materials with a mixer for 5-10 minutes, then use a 10,000-horsepower machine (internal mixer) to heat to 140°C-150°C and squeeze the material for 5-7 minutes. Roller kneading, four-roller calender compression, thickness control about 1.0mm, cooling, coiling about 250m per bundle, to obtain B...

Abstract

The present invention relates to a thermoplastic foaming polyurethane fiber board, a production method and uses thereof. The thermoplastic foaming polyurethane fiber board comprises an A surface layer, a B middle layer and a C bottom layer, wherein the A surface layer, the B middle layer and the C bottom layer are integratedly compounded from top to bottom, the A surface layer is a sheet material prepared by carrying out mixing calendaring on a TPU resin, a filler, a fire retardation agent, a stabilizer, a lubricant and a colorant according to a certain ratio, the B middle layer is a layer prepared by foaming the sheet material prepared by carrying out mixing calendaring on a TPU resin, a filler, a fire retardation agent, a stabilizer, a lubricant and a colorant according to a certain ratio, and the C bottom layer is a layer prepared by drying a fiber cloth impregnated with a TPU composition. The thermoplastic foaming polyurethane fiber board can be used as flooring boards, wall panels, roof hanging plates and indoor partition boards, and can be used for production of furniture materials and various building materials.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a thermoplastic foamed polyurethane fiber board, its production method and application. The thermoplastic foamed polyurethane fiber board includes A surface layer, B middle layer and C bottom layer which are combined from top to bottom , wherein, the A surface layer is a sheet prepared by mixing and calendering TPU resin, filler, flame retardant, stabilizer, lubricant and colorant in proportion, and the B middle layer is made of TPU resin, filler, flame retardant, stabilizer Agent, lubricant, foaming agent and colorant are mixed and calendered in proportion to the layer obtained by foaming the prepared sheet, and the C bottom layer is the layer obtained by drying the fiber cloth impregnated with the TPU composition. The thermoplastic foamed polyurethane fiber board according to the present invention can be used as a floor board, a wall board, a roof hanging board, an i...
