Problems solved by technology

[0003] Since the base layer of the reinforced composite floor is high-density fiberboard, high-density fiberboard is made of wood fiber and urea-formaldehyde resin at high temperature; so the floor feels hard and lacks elasticity; it has a tendency to absorb moisture, deform and arch
At the same time, the residual formaldehyde in the floor pollutes the air for a long time, endangering human health

Embodiment Construction

[0017] First put the unsaturated polyester resin into the reaction kettle, start stirring, and then put in the low-shrinkage additive; tert-butyl peroxybenzoate; zinc stearate, and heavy calcium carbonate and stir evenly for 2 hours. Then put the paste into the thickening barrel by 100kg each time, move the thickening barrel under the high-speed mixer, add light magnesium oxide and stir at a high speed for 5 minutes. Pour the thickened paste into the hopper of the sheet machine; the glass fiber is introduced into the distributor, and the sheet machine is started to press the sheet. Move the pressed sheet to a curing room for curing at 30°C for 48 hours. The cured sheet is cut into pieces according to the specifications, and the wood grain paper is laid on the upper surface of the two overlapping sheets, put into the mold and pressurized at 16Mpa, the temperature is 155°C, and the pressure is held for 3 minutes to release the mold. Spray Al on the upper surface after the mold ...

Abstract

A glass fibre reinforced composite floor is prepared through mixing unsaturated polyester resin, trigger, demoulding agent, filler, thickening agent and low-shrinkage additive together, adding glass fibres, pressing to obtain sheet, ageing, laying surface decoration layer, high-temp die pressing and surface antiwear treating. Its advantages include high elasticity, no deformation, high antiwear nature, flame retardation and no air pollution.

Description

1. Technical field [0001] The invention belongs to a method for making reinforced composite wood flooring. 2. Background technology [0002] The reinforced composite floor before the present invention is generally made of three layers of materials, which are respectively from top to bottom: surface layer, base material layer and moisture-proof layer. The surface layer is composed of wear-resistant layer and decorative layer. The wear-resistant agent is to uniformly press a layer of wear-resistant agent on the floor surface, and the decorative layer is made of a kind of melamine-treated thin paper, which presents wood patterns and patterns through computer simulation. The substrate layer is high-density fiberboard, and the moisture-proof layer is plastic film. [0003] Since the base layer of the reinforced composite floor is high-density fiberboard, high-density fiberboard is made of wood fiber and urea-formaldehyde resin at high temperature; therefore, the floor feels har...
