Abstract
A non-toxic adhesive for building, paint, paper, artificial board, etc. is prepared from polyvinyl alcohol, sugar, acid and water through dissolving polyvinyl alcohol in water at 80-100 deg.C while stirring, adding sugar and acid, reaction at 80-100 deg.C for 2-8 hrs, regulating pH=6-8, and cooling. Its advantages are high adhesion and no environmental pollution.
Description
Technical field
The present invention relates to a kind of tackiness agent and preparation method thereof, particularly a kind of water-soluble green non-poisonous tackiness agent and preparation method thereof, this tackiness agent can be used for laminated product, artificial board, adhesive for building, interior wall coating, paper product and stationery with glue etc.
Background technology
At present, generally contain benzene, substituted benzene or formaldehyde at artificial board, adhesive for building, interior wall coating, stationery with the tackiness agent of uses such as glue and shoe-making industry, the existence of these objectionable impuritiess influences HUMAN HEALTH.For protecting environment, safeguarding the healthy of people, the research of the tackiness agent of asepsis environment-protecting is the trend of development.The polyvinyl formal tackiness agent is commonly called as 107 glue, is widely used now a kind of tackiness agent, and cost is low, and adhesive effect is good.But because this tackiness agent contains a large amount of free formaldehydes, in use be discharged in the environment, directly influence HUMAN HEALTH, existing one of improve one's methods is to add formaldehyde-trapping agent, can use the vulcabond modification in addition, but the two can not tackle the problem at its root all, the former in use, because the effect of light, oxygen, enzyme, heat, this tackiness agent also can decompose emits formaldehyde, and this influence almost is secular.Though the latter does not have formaldehyde to discharge, the toxicity of vulcabond own is just very big, and costs an arm and a leg.
Summary of the invention
The green non-poisonous tackiness agent that the purpose of this invention is to provide a kind of, environmental sound nontoxic to human body is used in particular for adhesive for building, interior wall coating, paper product, artificial board and stationery with glue etc.
Another object of the present invention provides the preparation method of above-mentioned green non-poisonous tackiness agent.
A kind of green non-poisonous tackiness agent provided by the invention comprises following component:
