Problems solved by technology

CN 1484184A discloses a kind of laminate flooring (Fig. 1) with V-groove structure, because impregnated melamine-formaldehyde resin and through pre-cured wear-resistant paper and decorative paper are brittle, according to its disclosed manufacturing method, adopt The steel plate with V-shaped ribs directly presses the wear-resistant paper, decorative paper, MDF and balance paper, which will easily cause the wear-resistant paper or decorative paper to be brittle, and the yield of the product is low
In actual production, although the MDF substrate is hot-pressed with a steel plate with V-shaped ribs first, and then the wear-resistant paper, decorative paper, MDF and balance paper are subjected to secondary hot-press composite molding, which can improve the yield, but not only Increases production costs, reduces production efficiency, and reduces mechanical properties due to repeated heating of the MDF substrate

Embodiment 1

[0030] 21.5 parts by weight of the bamboo fiber spraying of 100 parts by weight of the drying process are made of 5 parts by weight of anti-mold agent, 1.5 parts by weight of curing agent, 3 parts by weight of paraffin emulsion waterproofing agent and 12 parts by weight of urea-formaldehyde glue; Moso bamboo is cut into bamboo wires with a diameter of 0.6mm±0.20 and then woven into a net shape. When paving and forming, the bamboo wire mesh is placed in the bamboo fiber, pre-pressed, and the steel formwork with V-shaped ribs on the upper formwork is used for heating. The thickness is controlled to be about 8mm±0.20, the hot-pressing temperature is 160-165°C, and the hot-pressing cycle is 270s; after curing and sanding, the finished reinforced medium density fiberboard is obtained.

Embodiment 2

[0032] Spray 21.5 parts by weight of 5 parts by weight of antifungal agent, 1.5 parts by weight of curing agent, 3 parts by weight of paraffin wax emulsion waterproofing agent and 12 parts by weight of urea-formaldehyde glue to the dried straw fiber of 100 parts by weight. , pre-press after paving and molding, cut the moso bamboo into bamboo wires with a diameter of 0.6mm±0.20 and then weave them into a net shape, place the bamboo wire mesh on the upper and lower surfaces of the green body, and use a steel formwork with V-shaped convex ribs on the upper formwork Carry out hot pressing, control the thickness of about 8mm±0.20, hot pressing temperature 160-165 ℃, hot pressing cycle 270s; after curing and sanding, the finished reinforced medium density fiberboard is obtained.

Embodiment 3

[0034] 21.5 parts by weight of 5 parts by weight of antifungal agent, 1.5 parts by weight of curing agent, 3 parts by weight of paraffin wax emulsion waterproofing agent are sprayed on the mixed fiber made up of 70 parts by weight of straw fiber and 30 parts by weight of bamboo fiber after drying. and 12 parts by weight of urea-formaldehyde glue, pre-press after paving and forming, cut the moso bamboo into bamboo wires with a diameter of 0.6mm ± 0.20 and weave them into a mesh, and place the bamboo mesh on the upper and lower surfaces of the green body , using the steel formwork with V-shaped convex ribs on the upper formwork for hot pressing, the thickness is controlled to be about 8mm±0.20, the hot pressing temperature is 160-165°C, and the hot pressing cycle is 270s; after curing and sanding, the finished product is reinforced with medium density fiberboard.

Abstract

The invention relates to a strengthened middle-density fiber plate, wherein its upper face can preset V-shaped, arc, or other grooves, to improve combine strength, simplify production and reduce pollution. In the MDF process, it synchronously performs V-shaped, arc or other grooves to reduce the cost of following wood plate production. The invention adds anti-fungus agent into urea-formaldehyde glue and wax emulsion waterproof agent, to improve fungus-proof property and application.

Description

Technical field: [0001] The invention relates to reinforced medium-density fiberboards, in particular to reinforcing medium-density fiberboards with bamboo silk or brown silk. technical background: [0002] Wood fiberboard is a wooden board product made by sizing wood fibers and hot pressing, especially with a density of 0.45-0.88g / cm 3 Medium-density fiberboard (MDF) is widely used as a base material for furniture and flooring because of its low price and good performance. With the development of the national economy, it stimulates the continuous growth of the furniture and laminate flooring manufacturing industry, and the demand for MDF is also increasing. [0003] However, my country is a country with a relative lack of forest resources, and the supply of timber raw materials is tight. Especially, the country implements natural forest protection projects and implements a comprehensive ban on logging. Therefore, many MDF manufacturers have been or will soon face the thre...
