Description
Technical field
The present invention relates to a kind of stationery, a kind of no free formaldehyde PVA solid glue sticks and its preparation side are referred specifically to
Method.
Background technology
Solid gum is because of its health easy to use, it has also become liquid glue renewal product.It is existing as stationery
Solid adhesive is with aliphatic acid mainly with water-soluble synthetic resin, polyvinyl alcohol or polyvinylpyrrolidone etc. for adhesive
Forming agent, using water as solvent.
Solid gum currently on the market is substantially using polyvinyl alcohol and polyvinylpyrrolidone as adhesive.Polyethylene pyrrole
Pyrrolidone solid gum is because its cost is higher smaller in occupation rate of market, and mass selling is essentially all polyvinyl alcohol in market
Solid gum is received by the market because of its cheap has excellent performance.But the production of polyvinylalcohol solids glue must add formaldehyde and change
Property, otherwise bonding force and stability are unable to reach requirement, and this production method causes product finally to have free formaldehyde
In the presence of.It being provided according to solid gum standard QB/T2857-2007, the content of free formaldehyde must not exceed 0.1% in solid gum, if
It is exceeded to generate serious harm to health and environmental protection.However, solid gum is in the industry cycle still skill except free formaldehyde so far
Art problem, substandard product is still in production and sales in the market.Each relevant departments national in recent years repeatedly spot-check solid gum product,
As a result very pessimistic, using low-cost polyvinyl alcohol as the solid gum of raw material, free formaldehyde content seldom complies with standard.
