Abstract
The invention discloses a kind of forest-friendly building timbers adhesive, by polyvinyl alcohol, glucomannoglycan, chitosan, the material such as deionized water is prepared from.The forest-friendly building timbers adhesive of the present invention, uses the raw material being inexpensively readily available to prepare adhesive, and without any poisonous and harmful component, environmental protection, and readily biodegradable.According to certain ratio mixing glucomannoglycan, chitosan, polyvinyl alcohol, three has the good compatibility, and three unit is blended strong interactions the such as the hydrogen bond of generation and makes glue surface define obvious network structure, not only can ensure bonding strength but also improve resistance to water.
Description
Technical field
The invention belongs to adhesive technical field, be specifically related to a kind of forest-friendly building timbers adhesive.
Background technology
Natural polymer has been used as based Wood Adhesives, the durability relatively low due to it and resistance to water, is synthesized resin
Adhesive is replaced.Adhesive made of synthetic resin has many advantages, such as high intensity, enhanced water resistance, but there is Form aldehyde release and pollutes
The problems such as environment.Along with the growing interest of people's environmental pollution, the research and development polymer-based adhesive of new type natural is
The task of top priority of timber industry.
Glucomannoglycan is deposit polysaccharide contained in Araeceae konjac tuber, has good bridging property, film property
And gelation.Chitosan is nitrogenous polysaccharose substance, has many unique biological activitys, and its nontoxic, bio-compatible
Property good, be also easy to degraded, nature yield be only second to cellulose, reproducible natural macromolecular material chitin,
Hydrolyzed under basic conditions deacetylation, and a kind of biopolymer obtained.Polyvinyl alcohol is a kind of water soluble polymer, nontoxic
Tasteless, can be used for preparing aqueous environment protection adhesive.It is widely used as adhesive by all trades and professions.But simple polyvinyl alcohol
Glue, its water resistance and adhesive property are poor, are of limited application.
Summary of the invention
A kind of forest-friendly building timbers adhesive of the present invention.Technical scheme is as follows:
A kind of forest-friendly building timbers adhesive, it is characterised in that be made up of the raw material of following parts by weight:
Polyvinyl alcohol 20-40 part
Glucomannoglycan 20-30 part
Chitosan 15-25 part
Deionized water 20-40 part.
Preferably, the molecular weight of described polyvinyl alcohol is at 15-20 ten thousand.
Preferably, described glucomannoglycan content is more than 95%.
Beneficial effects of the present invention: the forest-friendly building timbers adhesive of the present invention, uses the raw material being inexpensively readily available to prepare
Adhesive, and without any poisonous and harmful component, environmental protection, and readily biodegradable.According to certain ratio mixing Portugal
Sweet polysaccharide, chitosan, polyvinyl alcohol, three has the good compatibility, and three unit is blended the strong phases such as the hydrogen bond of generation
Interaction makes glue surface define obvious network structure, not only can ensure bonding strength but also improve resistance to water.
Specific embodiment
Embodiment 1: a kind of forest-friendly building timbers adhesive, it is characterised in that be made up of the raw material of following parts by weight:
Polyvinyl alcohol 28 parts
Glucomannoglycan 28 parts
Chitosan 18 parts
Deionized water 26 parts.
The molecular weight of above-mentioned polyvinyl alcohol is at 15-20 ten thousand.
Above-mentioned glucomannoglycan content is more than 95%.
Embodiment 2: a kind of forest-friendly building timbers adhesive, it is characterised in that be made up of the raw material of following parts by weight:
Polyvinyl alcohol 35 parts
Glucomannoglycan 22 parts
Chitosan 20 parts
Deionized water 23 parts.
The molecular weight of above-mentioned polyvinyl alcohol is at 15-20 ten thousand.
Above-mentioned glucomannoglycan content is more than 95%.
Described above is not limitation of the present invention, and the present invention is also not limited to the example above, the art general
Logical technical staff, in the essential scope of the present invention, the change made, retrofits, adds or replaces, should belong to the guarantor of the present invention
Protect scope.
