Problems solved by technology

In this patent, melamine is used to modify urea-formaldehyde resin to reduce the content of free formaldehyde in the resin. However, it is well known that melamine has adverse effects on children's development. Urea-formaldehyde resin binder, although the formaldehyde content is reduced, but the presence of melamine still affects the healthy growth of children

Embodiment Construction

[0041] The manufacturing method of environmentally friendly flame-retardant medium-density fiberboard for reinforced wood flooring according to the present invention includes the following steps:

[0042] 1) Material preparation

[0043] Mix the reed stalks and bean stalks in a weight ratio of 1 to 2:1, and send them to an oven after cleaning to a water content of 15 to 20% to obtain a mixture;

[0044] 2) Raw material slices

[0045] The dried mixture is fed into a drum chipper for slicing to obtain fragments with an average length of 5-7cm, which are screened by a screening machine to remove fragments, debris and impurities;

[0046] 3) Steam and soften

[0047] Steam the sliced ​​mixture under steam at 150-170°C to soften the mixture, with a saturated steam pressure of 1 to 3 MPa, and a cooking time of 5 to 8 minutes;

[0048] 4) Preparation of waterproof emulsion

[0049] Heat the paraffin wax and glyceryl stearate to melt, stir, and raise the temperature to 80~90℃. Add oleic acid and ...

Abstract

The invention provides a manufacturing method for an environment-friendly inflaming retarding medium density fiberboard for laminate wood flooring. The method includes the following steps of (1) material preparation, (2) raw material slicing, (3) stewing and softening, (4) preparation of waterproof lotion, (5) hot grinding, (6) gluing, (7) drying, (8) laying and prepressing, (9) hot pressing and (10) edge cutting, sanding and storage. The medium density fiberboard obtained through the manufacturing method is good in first viscosity, high in strength, good in inflaming retarding and heat resistance, nontoxic and environmentally friendly.

Description

Technical field [0001] The invention belongs to the technical field of fiberboard manufacturing. Specifically, a method for manufacturing an environmentally friendly flame-retardant medium density fiberboard for reinforced wood flooring is designed. Background technique [0002] Density board, also called fiberboard, is a man-made board made of wood fiber or other plant fibers and applied with urea-formaldehyde resin or other suitable adhesives. According to the different density, it is divided into high density board, medium density board and low density board. Mainly used for laminate flooring, door panels, partition walls, furniture, etc. Density boards are mainly used for the surface treatment of oil mixing process in home furnishings; generally, medium density boards are used for furniture, because the density of high-density boards is too high. It is easy to crack, so there is no way to make furniture. Generally, high-density boards are used for indoor and outdoor decorat...
