Abstract
The invention discloses a novel water soluble phenolic resin adhesive synthetic process, and relates to the technical field of chemical industry; a water soluble phenolic resin adhesive is obtained through carrying out a full reaction of a colorless phenol crystal molten by heating with a sodium hydroxide aqueous solution (0.1 mol/L) and formaldehyde. The synthetic process has the beneficial effects that the synthetic process has the advantages of convenient and simple preparation, environmental protection, no pollution, easy availability of raw materials, less equipment investment, pure quality, and convenient operation; and the prepared water soluble phenolic resin adhesive is good in use effect, safe and reliable.
Description
Technical field
The present invention relates to chemical technology field, be specifically related to a kind of novel water-soluble phenolic resin adhesive synthesis technique.
Background technology
Resol is industrialized synthetic resins the earliest, is also the synthetic adhesive first occurred, or the first sqtructural adhesive that modification is obtained, at first for aircraft industry.Although the appearance of novel adhesive, in a lot of, instead of synvaren, because of the particular advantages of itself, its importance did not still subtract originally, still had larger development and application.Resol polarity is comparatively large, and to metal with majority is nonmetal good cementability, bonding strength is higher.Owing to there is a large amount of phenyl ring in resol, can be cross-linked into body structure again, rigidity is comparatively large, and thus thermotolerance is high, creep resistance, resistance to ablation, good stability of the dimension.Water-fast, oil resistant, wear-resisting, resistant to chemical media, resistance to mould, ageing-resistant etc., electrical insulation capability is excellent, apply very extensive, but in the technique of current industrial production Phenol aldehyde resin, all there is the problems such as yield is low, purity not high pollution is serious, and production technique is comparatively complicated, be difficult to meet human wants.
Summary of the invention
It is high that technical problem to be solved by this invention is to provide a kind of quality, the water-soluble phenolic resin adhesive synthesis technique that preparation technology is simply novel.
Technical problem to be solved by this invention realizes by the following technical solutions:
Novel water-soluble phenolic resin adhesive synthesis technique, is characterized in that: comprise following processing step,
A. the three-necked flask of a 500ml is chosen as reaction flask.

C. the aqueous sodium hydroxide solution (0.1mol/L) taking 120-130ml adds in the reaction flask in above-mentioned steps b, temperature to be controlled at 40-50 DEG C of isothermal reaction 20-30min after particle appears in inside when its solution pinkiness.
D. the formaldehyde taking 48-49g is thrown in the reaction flask in above-mentioned steps c, after stirring 2-4min, temperature is continued remain on 45-50 DEG C of isothermal reaction 25-35min, in 80min, then has 50 DEG C to rise to 87 DEG C, then after 25min rises to 95 DEG C by 87 DEG C insulation reaction 20min.
E. by 95 DEG C, 82 DEG C are cooled to above-mentioned reacted solution in 30min, again add the formaldehyde insulation reaction 10-20min of 12-12.5g.
F., after above-mentioned steps e reaction terminates, in 30min, temperature is risen to 92 DEG C of insulation reaction 5-10min by 82 DEG C again.
G. treat that in above-mentioned steps f, in reaction flask, solution is rendered as glue, when color is dark-brown, solution temperature is controlled at 92-96 DEG C of insulation 15-25min.
H., after above-mentioned steps g reaction terminates, it is (100-200) * 10 that sample thief detects viscosity
