Abstract

The invention discloses a strong-adhesion liquid wood adhesive powder, relates to the adhesive field, and particularly relates to an environment-friendly adhesive without wood adhesive powder. The strong-adhesion liquid wood adhesive powder comprises following components in parts by mass: 5-10% of polyvinyl alcohol, 5-8% of calcium chloride, 20-30% of calcium carbonate, 8-15% of starch, 25-35% of A material, 5-15% of diatomite, 0.2-1% of antifoaming agent, 0.2-1% of preservative, 0.3-1% of dispersant, 1-2% of plasticizer and 20-30% of water. The strong-adhesion liquid wood adhesive powder prepared by the above formula has strong adhesion, no benzene, no aldehyde, no toxicity and no harm, and is environment friendly, low in carbon, high in solid content, small in shrinkage, good in initial adhesion, fast in drying speed, resistant in freezing resistance and easy in gluing and the like.

Description

Powerful liquid ureaformal dehyde resin glue
Technical field
The present invention relates to adhesive area, especially environment-friendly type, the non-tackiness agent containing ureaformal dehyde resin glue.
Background technology
Ureaformal dehyde resin glue is to be coordinated and formed by pulverous urea-formaldehyde resin, toughener and solidifying agent.Before use, be first dissolved in water, after mixing, can be widely used in the tackiness agent of wood working industry.It can cold-adhered, heat bonding.It is high that this glue has bonding strength, is easy to the feature of preserving.The contained formaldehyde amount of other ureaformal dehyde resin glue of E0 level can be less than 0.5mg/L by detecting, and E1 level is exactly to be greater than 0.5mg/L and to be less than 1.5mg/L, and E2 is greater than 1.5mg/L exactly and is less than 5mg/L.Substantially ureaformal dehyde resin glue can only be accomplished E2 rank now, if accomplish the words (not adding under the prerequisite that properties-correcting agent is catching agent for free formaldehyde) of E1 or even E0, that just only has this product of cyanurotriamide modified urea resin rubber powder to accomplish.As from the foregoing, although ureaformal dehyde resin glue is widely used because of its excellent performance at wood working industry, fitting-up industry, construction industry, but because of it, to have corrodibility, ageing resistance, weathering resistance poor, its use range is limited by very large, and is difficult to meet the technical requirements of electronic information and space flight and aviation industry.Again because it contains formaldehyde etc. to the poisonous and hazardous composition of human body, and contaminate environment impairs one's health, and is limited to use.Therefore to the manufacturing technology of existing tackiness agent, must be improved, to meet, people are safe, relieved, the actual user demand of environmental protection.
Summary of the invention
For overcoming the defect of above-mentioned prior art, the invention provides a kind of brute force, the environment-friendly water-based tackiness agent of weather-proof, anti-aldehyde, without benzene, simple, easy to use without aldehyde, nontoxic, harmless, safety and environmental protection, making, not only can substitute ureaformal dehyde resin glue, and can absorb the objectionable constituent such as formaldehyde, more, applicable to electronic information industry and aerospace industry, can meet its technical requirements.
Technical scheme of the present invention is: a kind of powerful liquid ureaformal dehyde resin glue, is characterized in that being comprised of the component of following mass fraction:

(5) the polyvinyl alcohol solution in polyvinyl alcohol dissolution kettle is transported in polymeric kettle, and adds alkylphenol polyoxyethylene, sodium lauryl sulphate, sodium ethylene diamine tetracetate, and stirring makes its dissolving;
By monomer scale tank to the 15--20% that adds mix monomer total amount in polymeric kettle, by initiator scale tank, to the 30--40% that adds solution total amount in polymeric kettle, stirred 30 minutes;
(7) give polymerization kettle temperature raising, make polymerization temperature in the kettle rise to 60--65 ℃, polyreaction starts, and refluxing appears in reflux exchanger;
(8), while reducing wait refluxing, start in polymeric kettle, to drip mix monomer by monomer scale tank; By initiator scale tank, in polymeric kettle, drip ammonium persulfate solution, control polymeric reaction temperature at 78--80 ℃, in monomer scale tank, mix monomer dripped off in 8 hours, then added ammonium persulfate solution in whole initiator scale tanks;
(9) give polymerization kettle temperature raising, make polymerization temperature in the kettle rise to 90--95 ℃, be incubated 30 minutes;
(10) then to polymeric kettle cooling, make polymerization temperature in the kettle be down to 50 ℃, then add saleratus solution by pH buffer reagent scale tank, by softening agent scale tank, add whole softening agent, add sanitas, be fully uniformly mixed;
(11), after above-mentioned finished product being filtered, put into storage tank.
The powerful liquid ureaformal dehyde resin glue that adopts above-mentioned formula and technique to make, has superpower cohesive force, without benzene, without aldehyde, nontoxic, harmless, environmental protection, low-carbon (LC), also has that solid content is high, shrinking percentage is little, tack is good, rate of drying antifreeze, easy gluing etc. soon.
