specific Embodiment approach 1

[0028] Specific embodiment one: a kind of birch bark composite material of this embodiment, this birch bark composite material comprises birch bark particle and polyurethane glue; Described birch bark particle and polyurethane glue mass ratio is 1: (4~6).

[0029] This embodiment includes the following beneficial effects:

[0030] One, the present invention overcomes the inherent train of thought that only adopts cork wood as the raw material of cork processing in the field of cork processing technology, also overcomes in existing wood processing and application technology field, only the development and utilization of birch bark are limited to: fuel or As an inherent idea in the technical field of craft decoration materials. The invention fully exploits the inherent specificity of birch bark, introduces it into the technical field of cork processing, and obtains unexpected technical effects after long-term tests.

[0031] 2. Because birch bark is also an excellent cork bark...

specific Embodiment approach 2

[0032] Embodiment 2: This embodiment differs from Embodiment 1 in that the mass ratio of birch bark particles to polyurethane glue is 1:5. Other steps and parameters are the same as in the first embodiment.

specific Embodiment approach 3

[0033] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that: the particle size of the birch bark particles is 60-180 mesh. Its steps and parameters are the same as those of the specific embodiment one or two.

Abstract

The invention relates to a bark compound material and a preparation method and application thereof, in particular to a birch bark compound material and a preparation method and application thereof, and aims to solves the problems that utilization of birch bark by the prior art is low in efficiency, the birch bark has narrow application fields and the market is in shortage of cork barks. The birch bark compound material is composed of birch bark granules and polyurethane adhesive. The preparation method includes: 1, pretreating birch bark; 2, crushing and screening the birch bark; 3, performing mixing; and 4, performing forming and cutting. The birch bark compound material has the advantages of moisture resistance, electric insulation, heat preservation, thermal insulation, wear resistance, high comfort, high decorativeness and environmental friendliness and health. The invention is applicable to preparation and application of the birch bark compound material.

Description

technical field [0001] The invention relates to a bark composite material and its preparation method and application. Background technique [0002] Cork (English professional expression: cork, phellem), commonly known as cork. Ancient Egypt, Greece and Rome used to make fishing nets, insoles, bottle stoppers, etc. Cork has been recorded in the Spring and Autumn Period of China. The cork products developed in the international and domestic markets include cork plugs, cork pads, handicrafts, cork wallboards, cork flooring, etc.; according to the preparation process, they are divided into natural cork products, baked cork products, glue baked cork products, cork rubber products, etc.; Both birch bark and oak bark are natural materials, rich in cork resin, with a cork layer, both of which have natural qualities, are not rotten, non-toxic, tasteless, moisture-proof, water-resistant, oil-resistant, acid-resistant (thin), elastic, Wear-resistant, heat insulation, noise reduction...
