Problems solved by technology

There are many types of adhesives currently used, but the existing general adhesives contain formaldehyde, benzene, toluene and other components that are poisonous to the human body.
These toxic components have caused serious pollution to people's environment and endangered health. These harmful components have certain damage to eyes, skin, respiratory system and lung function. Long-term inhalation of a small amount of formaldehyde can also cause chronic poisoning and cause strong mutagenesis. sex and carcinogenicity

Abstract

The invention relates to an adhesive, particularly an environment-friendly adhesive and a preparation method thereof. The environment-friendly adhesive comprises 8-11% of starch, 16-22% of soybean protein powder, 4-5% of initiator, 5-7% of talcum powder, 1-1.5% of preservative, 5-6% of tackifier, 3-4% of rosin modifier, 2-3% of buffering agent and the balance of water. The preparation method comprises the following steps: uniformly mixing the starch, soybean protein powder, initiator, tackifier and partial water at 85-90 DEG C, adding the talcum powder, preservative, tackifier, rosin modifier, buffering agent and the rest water, and continuing stirring at 70 DEG C for 2 hours. The adhesive is green and environment-friendly, does not contain any environment-polluting component, can not injure the human health in the use process, has the characteristics of higher bonding strength, higher water resistance, higher heat resistance, lower curing temperature, excellent anticorrosion protective action and the like, and belongs to an environment-friendly adhesive.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to an environmentally friendly adhesive and a preparation method thereof. Background technique [0002] At present, adhesives have been widely used in people's production and life, especially in industries such as furniture manufacturing, decoration and shoemaking. There are many types of adhesives used at present, but the existing general adhesives all contain formaldehyde, benzene, toluene and other components that are poisonous to the human body. These toxic components have caused serious pollution to people's environment and endangered health. These harmful components have certain damage to eyes, skin, respiratory system and lung function. Long-term inhalation of a small amount of formaldehyde can also cause chronic poisoning and cause strong mutagenesis. sex and carcinogenicity. It can be seen that the production of a green and environmentally friendly adhesive is the development tre...
