Abstract

The invention provides a composite adhesive for stalk artificial boards and a preparation method thereof. The composite adhesive does not contain formaldehyde and is nontoxic. The problem of harm to the health caused by the use of formaldehyde-type adhesives is solved. Meanwhile, compared with the technical scheme using isocyanate, the composite adhesive has the advantages that the cost is greatly reduced; the bonding performance of inorganic binding material is enhanced by sufficiently using chloride ion molecular groups in polyamine epoxy chloropropane, so that the performance index of the plate in all aspects is greatly enhanced. The preparation method of the composite adhesive is simple; the use is easy; the cost of the composite adhesive can be reduced; the thermal curing intensity of the adhesive is enhanced.

Description

technical field [0001] The invention relates to the technical field of wood-based board adhesives, in particular to a composite adhesive used for straw-based boards and a preparation method thereof. Background technique [0002] my country's straw resources are abundant, and the waste is serious, and it has caused a series of problems such as environmental pollution. After the straw is pretreated, pressing it into a plate is one of the effective ways to rationally utilize straw resources. Straw raw materials come from a wide range of sources, and they are pressed into straw-based panels as building wall materials to produce energy-saving and environmentally friendly passive houses, so that the environmental and ecological problems caused by agricultural waste such as straw have been fundamentally resolved. The thermal insulation coefficient of straw wood-based panels is much higher than that of clay brick walls, while the heating heat consumption and heating cost are far lo...
