Abstract
An adhesive includes an organic material, an inorganic material, a curing agent and a catalyst. The adhesive is able to bond the wood material, especially recycled wood material. The wood material is not necessary to have any pretreatment like removing color, pigment or plastic lining so as to be introduced to the film process directly. After breaking and adjusting the moisture content of the wood material, it can be mixed with the adhesive and hard pressed into wood product with good duration and quality. The adhesive and the production method of wood board is able to ameliorate the problem of the conventional water based adhesive to save energy and processing time.
Claims15
An adhesive composition in powder form for making a wood board comprising:
- an organic material including protein and/or starch in a range of 30%-80% w/w referring to the weight percent based on a total weight of the adhesive composition in powder form;
- an inorganic material in a range of 10%-40% w/w referring to the weight percent based on a total weight of the adhesive composition in powder form, the inorganic material comprising a mixture of group IA metal oxides and carbonates or a mixture of group HA metal oxides, hydroxides and carbonates;
- a curing agent contains one or multiple types of boron compounds in a range of 5%-30% w/w referring to the weight percent based on a total weight of the adhesive composition in powder form;
- and
- a catalyst contains a group IA metal hydroxide in a range of 0%-3% w/w referring to the weight percent based on a total weight of the adhesive composition in powder form, wherein
- when the organic material is exposed to moisture and heat, the organic material will possess a fluid nature.
