specific Embodiment approach 1

[0008] Embodiment 1: The biohemoglobin protein wood adhesive in this embodiment is biohemoglobin protein powder; wherein the biohemoglobin protein powder is porcine hemoglobin powder, bovine hemoglobin powder or sheep hemoglobin powder.

specific Embodiment approach 2

[0009] Specific embodiment two: the biohemoglobin protein wood adhesive of this embodiment is composed of 50% to 80% of biohemoglobin protein powder and 20% to 50% of reinforcing agent by mass percentage; wherein the biohemoglobin protein powder is porcine hemoglobin powder , bovine hemoglobin powder or sheep hemoglobin powder; the reinforcing agent is flour, ore powder, urea, melamine, melamine resin glue, melamine modified urea-formaldehyde resin glue or phenolic resin glue.

specific Embodiment approach 3

[0010] Embodiment 3: This embodiment differs from Embodiment 2 in that the biohemoglobin protein wood adhesive is composed of 55% to 75% of biohemoglobin protein powder and 25% to 45% of reinforcing agent. Others are the same as in the second embodiment.

Abstract

The invention discloses a biological corpuscle protein wood adhesive, relates to a wood adhesive, and solves the problems that the prior synthesized resin adhesive releases formaldehyde, pollutes environment and harms human body. The biological corpuscle protein wood adhesive is biological corpuscle protein powder. The biological corpuscle protein wood adhesive consists of the biological corpuscle protein powder and a reinforcing agent. The biological corpuscle protein wood adhesive has the advantages that the biological corpuscle protein wood adhesive does not pollute the environment and has no harm to the human body, does not change production processes and parameters of the prior artificial boards after the adhesive is applied to adhering core boards, three-layer base materials of solid wood composite floors and multilayer floor base materials, and is easy to coat. Adhesive layers are even, and release amount of the formaldehyde is 0 to 0.4 milligram per liter.

Description

technical field [0001] This invention relates to wood adhesives. Background technique [0002] Synthetic resin adhesives are widely used in the wood-based panel production industry to decorate homes, offices and other places; synthetic resin adhesives will release formaldehyde gas, and the country's current mandatory limit standard for harmful substances in interior decoration materials is E1≤1.5mg / L, but after the existing synthetic resin adhesive is applied to the bonding of wood-based panels, formaldehyde will be released slowly for a long time, pollute the environment, and is harmful to the human body, often causing various diseases. Faced with increasingly stringent environmental protection regulations and consumption It is imperative to produce healthy, green and environmentally friendly adhesives. Contents of the invention [0003] The object of the present invention is to provide a biohemoglobin protein wood adhesive to solve the problem that the existing synthet...
