Problems solved by technology

[0003] However, wood-plastic panels in the prior art also have many disadvantages, such as: in a colder environment, the impact resistance is poor, and the nails are easy to crack during winter construction; the oxidation resistance, wear resistance, and aging resistance are poor. During the process, there will be problems such as serious surface wear and oxidative fading of wood-plastic panel furniture; poor thermal stability, easy to deform during summer construction; poor flame retardancy, and effective flame retardant effect cannot be achieved in case of fire

Abstract

The invention discloses a high-toughness flame-retardant foamed PVC wood-plastic board. The high-toughness flame-retardant foamed PVC wood-plastic board comprises PVC resin, fiber powder, nanometer light calcium carbonate, rutile titanium dioxide, methyltin mercaptide, antimony trioxide, polyacrylonitrile-based carbon fibers, a PVC flexibilizer, a coupling agent, liquid triphenyl phosphite, a PVC modification aid, chlorinated paraffin, silicone oil and an AC foaming agent. The invention also discloses a preparation method for the PVC wood-plastic board. The preparation method for PVC wood-plastic board in the invention is simple in process and easy to operate; and the prepared PVC wood-plastic board has a plurality of advantages like good thermal stability, good ageing resistance, good anti-oxidizability, good impact resistance, good wear resistance, good insulating properties and good flame resistance.

Description

technical field [0001] The invention relates to the technical field of building material wood-plastic panels, more specifically, to a high-toughness flame-retardant foamed PVC wood-plastic panel and a preparation method thereof. Background technique [0002] With the continuous growth of the building materials market, the market demand for wooden building materials is also rising sharply. Among them, the utilization rate of wooden formwork is very high, but wooden formwork consumes a lot of wood, and the reuse rate is low. The template must be surface treated, such as brushing the surface with anti-corrosion paint, etc. With the enhancement of people's awareness of environmental protection, people gradually pay more attention to the protection of trees. The traditional deforestation has gradually transformed into the current afforestation. Therefore, people urgently need a new type of material to replace wooden building materials. Wood-plastic formwork is a new type of form...
