Embodiment 1

[0015] Embodiment 1: this veneer composite material, it is made by the raw material of following weight ratio, Manila hemp pulp 20%, wood pulp 40%, chemical fiber 35%, bonding fiber 5%. The bonding fiber is water-soluble PVA, and the chemical fiber refers to vinylon.

[0016] The production technology of this veneer composite material mainly comprises the following steps;

[0017] 1) Beating with a beater: the beating concentration of wood pulp is 4-5%, the beating ampere is 65-70A, the beating time is 40-60 minutes, and the pulp quality requirements: percussion degree 15---18 (°SR), wet weight 14---16 (grams); the beating concentration of Manila hemp pulp is 3-4%, the beating amp is 60-65A, and the beating time is 30-50 minutes; the pulp quality requirements: percussion degree 14---16(°SR), The wet weight is 16---18 (grams); the chemical fiber is mainly loosened, and the fiber must be completely dispersed, and no drawing phenomenon is allowed;

[0018] 2) In the pulp storag...

Embodiment 2

[0039] Embodiment 2: The difference with Embodiment 1 is that this veneer composite material is made of the raw materials of the following weight ratio, Manila hemp pulp 40%, wood pulp 20%, chemical fiber 30%, bonding Fiber 10%, wherein said bonding fiber is water-soluble PVA, and chemical fiber refers to vinylon.

Embodiment 3

[0040] Embodiment 3: The difference with Embodiment 1 is that this veneer composite material is made of the raw materials of the following weight ratio, Manila hemp pulp 30%, wood pulp 20%, chemical fiber 40%, bonding Fiber 10%, wherein said bonding fiber is water-soluble PVA, and chemical fiber refers to vinylon.

Abstract

The invention relates to a wood compounded material, comprising by weight 20-40% of Manila sand slurry, 20-40% of wood slurry, 20-40% of chemical fiber which is vinylon and 3-10% of bonding fibre which is water miscible PVA. The production technology of the wood compounded material contains 1) beating by beater, 2) joining 1-% of PEO in drainer, 3) drying that original paper is formed by drying in dryer after forming in oblique graticule forming container, 4) coating by coater two times after loosening and it is cut into finish product by splitting machine. There are the merits that it is provided with adjacent crossbar strength ratio so as to solve the problem of wood strobilation and certain air permeability.

Description

technical field [0001] The invention relates to the field of wet-laid nonwoven fabrics, and mainly relates to a production process of veneer composite materials. Background technique [0002] Wood veneer composite material is one of the wet-laid nonwoven series products, mainly used in the wood decoration material industry, as an intermediate material between the veneer and the substrate, high-grade wood is made of veneer coils, and used to bond with low-grade wood materials It can be made into a solid veneer material that is both beautiful, strong and economical. This material has become one of the materials widely used in modern home decoration and furniture. There is no big quality problem when the veneer is directly bonded to the flat substrate, but when it is bonded to the curved substrate, such as making wooden moldings, due to the brittleness of the veneer, cracks are easy to appear at the corners of the bumps, which requires a certain distance between the veneer and ...
