Technical Field
The invention relates to a soybean protein glue board and shaving board gluing device and method, and belongs to the technical field of artificial board equipment.
Background
At present, the adhesive for the wood industry is still mainly 'formaldehyde-formaldehyde adhesive', and the consumption of urea-formaldehyde resin adhesive, phenol-formaldehyde resin adhesive and melamine-formaldehyde resin adhesive reaches about 500 ten thousand t (calculated by solid content 100%) every year. However, the aldehyde-based adhesive is not an environment-friendly product, and formaldehyde can be released by the aldehyde-based adhesive and the product thereof in the using process, so that formaldehyde pollution in air of workshops and living rooms is caused, and the physical and mental health of people is seriously threatened. In addition, since most of the raw materials for aldehyde-based adhesives are derived from non-renewable resources, research and development of renewable, environmentally friendly adhesives for wood are important issues in the wood industry today when resources are gradually depleted. Soybean protein glue and other natural renewable resources are increasingly gaining attention.
With the development of industrial modernization, the traditional labor-intensive artificial board manufacturing field is gradually eliminated, and the particle boards in the plywood are more and more popular in the market due to high automation degree, less labor and large output. However, the adhesives used in the production of the particle board are most common urea-formaldehyde resin adhesives produced by self, and the adhesives are still the mainstream of the existing particle board enterprises due to low price, but the application range of the particle board is greatly limited due to high free formaldehyde release amount of the adhesives.
The soybean protein glue is theoretically true for the production of shaving boards, but the production of the shaving boards by the soybean protein glue still has great difficulty for the existing production conditions. If the single-component soybean protein adhesive is adopted to produce the shaving board, the defects of high gluing difficulty, insufficient equipment and process conditions and the like exist; if the two-component soybean protein adhesive is adopted to produce the shaving board, the problems of uneven sizing and substandard product performance after sizing exist.
