Embodiment Construction

[0022] As shown in the figure, a woody formaldehyde-free floor base material fiberboard production process, using pine and poplar as raw materials, after chipping, screening to remove iron, fiber preparation and sizing drying, paving hot pressing, rough board treatment It is made by processes such as sanding and cutting boards. In the process of fiber preparation and sizing and drying, a certain proportion of fragrances such as jasmine or sandalwood are added to the waterproofing agent, and polyurethane adhesives are used instead of urea-formaldehyde resin adhesives. The specific The production process is as follows:

[0023] (1) Chipping, pine and poplar branches are transported from the raw material yard by the loader, sent to the chipper feeding machine, fed through the feeding equipment, sent to the chipper for chipping, and the wood chips are sent to the wood chips Yard storage;

[0024] (2) Screening and iron removal, 70% poplar wood chips and 30% pine wood chips are mi...

Abstract

The invention provides a fiberboard production process for an elecampane non-formaldehyde floor base material and relates to the technical field of artificial board production. The fiberboard production process comprises the steps of using pines and poplars as raw materials, chipping, screening and deironing, preparing fiber and sizing-drying, laying and hot-pressing, processing rough boards, sanding and cutting the boards and the like, a certain proportion of jasmine or sandalwood and other flavoring agents are added in a waterproof agent adopted in the fiber preparing and sizing-drying step, and an urea-formaldehyde resin adhesive is replaced by a polyurethane adhesive. In the fiberboard production process, a continuous flat pressing technology is adopted, and accordingly the elasticity modulus, static bending intensity and physical and mechanical properties of products are further improved by fully mixing the pines and poplars in certain proportion. The products do not contain formaldehyde and is good in waterproof performance by adopting the polyurethane adhesive to replace the urea-formaldehyde resin adhesive during production of fiberboards for floor base materials. In addition, a certain proportion of jasmine or sandalwood and other flavoring agents are added in the waterproof agent, so that the products have fragrance and have the advantages of being stable in quality, environment-friendly and healthy.

Description

technical field [0001] The invention relates to the technical field of wood-based panel production, in particular to a production process of fiberboard for wood-flavored formaldehyde-free floor substrates. Background technique [0002] Medium density fiberboard is a kind of man-made board made of small-diameter logs, harvesting and processing residues, sliced, cooked, fiber separated, dried, and then applied with urea-formaldehyde resin or other suitable adhesives, and then hot-pressed. MDF It has excellent mechanical properties, decorative properties and processing properties, and its development prospects are very broad. In recent years, the fiberboard industry has developed rapidly, and the phenomenon of product market segmentation has become increasingly clear. In particular, consumers have less environmental protection requirements for wood-based panels, and have put forward higher requirements for the smell of the product itself. Urea-formaldehyde resin adhesives cont...
