Embodiment 1
[0056] Such as figure 1 As shown, this embodiment provides a polyurethane composite floor, including a foam layer and a decorative layer arranged on the foam layer, the foam layer includes an intermediate core material 1, and the upper and lower parts of the intermediate core material 1 are respectively provided with continuous braided fibers layer, the continuous braided fiber layer on the upper part of the middle core material 1 is the upper continuous braided fiber layer 2, the continuous braided fiber layer on the lower part of the middle core material 1 is the lower continuous braided fiber layer 3, and the middle core material 1 is provided with several filling Voids, several filled voids are filled with polyurethane rigid foam.
[0057] Since this board is cured and shaped after foaming reaction, it has the effect of sound insulation and heat insulation. In addition, the continuous braided fiber layer provides horizontal and transverse bending force support for the boar...
Embodiment 2
[0064] This embodiment is optimized on the basis of the above-mentioned embodiment 1.
[0065] The rigid polyurethane foam is composed of the following components in parts by weight: 50 parts of polyether polyol, 50 parts of isocyanate, 20 parts of filler, 5 parts of coupling agent, 12 parts of flame retardant and 5 parts of auxiliary agent. The auxiliary agent is at least one of dispersant, film-forming auxiliary agent, thickener, defoamer, active agent, penetrating agent, toner and suspending agent. In this embodiment, the dispersant is selected, and the filler is sand, cement , quartz powder, heavy calcium powder, talcum powder, fly ash, mineral powder and silica fume at least one, select mineral powder in the present embodiment.
Embodiment 3
[0067] This embodiment is optimized on the basis of the above-mentioned embodiment 2.
[0068] The rigid polyurethane foam is composed of the following components in parts by weight: 40 parts of polyether polyol, 40 parts of isocyanate, 10 parts of filler, 3 parts of coupling agent, 8 parts of flame retardant and 3 parts of auxiliary agent.

Abstract
The invention relates to the technical field of composite structures, and discloses a polyurethane composite floor and a manufacturing process thereof. The polyurethane composite floor comprises a foaming layer and a decorative layer arranged on the foaming layer, the foaming layer comprises a middle core material, continuous woven fiber layers are arranged on the upper portion and the lower portion of the middle core material correspondingly, wherein the continuous woven fiber layer located on the upper portion of the middle core material is an upper continuous woven fiber layer, the continuous woven fiber layer located on the lower portion of the middle core material is a lower continuous woven fiber layer, a plurality of filling gaps are formed in the middle core material, and rigid polyurethane foams are loaded in the filling gaps. According to the polyurethane composite floor and the manufacturing process thereof, the polyurethane composite floor has the advantages of being low incost, high in weather resistance and wide in adaptability, a mold is adopted for integral forming, mutual catalytic curing is carried out through chemical internal energy of reaction of products, production energy consumption is greatly reduced, meanwhile, glue bonding is avoided, the polyurethane composite floor is more environmentally friendly and durable, and the processing procedures are simple.
Description
technical field [0001] The invention relates to the technical field of composite structures, in particular to a polyurethane composite floor and a manufacturing process thereof. Background technique [0002] With the continuous development of the economy, the living standards of the people have been greatly improved, but at the same time it has also brought about the extreme consumption of natural resources. The forest coverage of the earth is constantly decreasing. Facing the increasing scarcity of solid wood resources and global warming, The sea level continues to rise, while globalization brings abyssal impact. The environment in which human beings can survive is facing an unprecedented threat. [0003] In the face of the current market, whether it is solid wood flooring or PVC, PE wood-plastic flooring, there are many product defects. For example: the product is prone to shrinkage and deformation, powdering and chipping, aging and cracking, mildew, and many other produ...
