In summary it can be seen, glue performance prepared by embodiment of the present invention 1-5 not only environmental-protecting performance significantly promotes, and achieves the remarkable lifting of glue over-all properties simultaneously, has beyond thought technique effect.The indices embodied in his-and-hers watches 1 carries out global alignment, and applicant finds that the glue of embodiment 5 index all has the most excellent performance on indices, and embodiment 5 is most preferred embodiment of the present invention undoubtedly.
In conjunction with the excellent effect of the present invention, applicant sets forth component of the present invention and technique: glue of the present invention is enhancing ring guaranteed cost, have employed the consumption rationally reducing vinyl acetate, the technical thought of vinyl acetate is replaced with nontoxic polyvinyl acetate (PVA), because polyvinyl acetate (PVA) is not identical with the character of vinyl acetate, for meeting the technology stability prepared in the performance of glue and preparation process, need to regulate and control the ratio of polyvinyl acetate (PVA) and vinyl acetate, simultaneously must the selection of all the other components in concern system.Why applicant must use polyvinyl acetate (PVA) and vinyl acetate in same system, instead of abandon vinyl acetate completely, because generally adopt vinyl acetate as raw material production glue in prior art, the present invention retains use vinyl acetate and the technology of the present invention can be made to have very strong promotional value in system, existing glue production manufacturer can be made to be easy to accept the production technique of this improvement, but not brand-new production technique, make the technology of the present invention have good market using value; Take into account the consideration of production cost on the other hand.
Applicant is through great many of experiments, unexpected discovery, the weight ratio of polyvinyl acetate (PVA) and vinyl acetate is (700-1050): (300-350) just realizes the goal of the invention of the present invention, if the consumption of vinyl acetate exceeds this ratio, then the glue environmental-protecting performance of final preparation just cannot significantly promote, little with the common glue environmental-protecting performance difference of prior art, if the too high levels of polyvinyl acetate (PVA), preparation technology's reaction stability then can be caused to be deteriorated, wayward, glue over-all properties is deteriorated, and causes the over-all properties of final glue significantly to promote.
Dibutyl phthalate and diethylene glycol dibenzoate are softening agent, and the present invention is the reaction system adapting to compound material, have employed the way simultaneously adding dibutyl phthalate and diethylene glycol dibenzoate; Octanol and Virahol, can not only be used for dissolving dibutyl phthalate and diethylene glycol dibenzoate, is conducive to the degree of adhesion improving glue; Can also play the effect of a part of defoamer, what be conducive to time prepared by glue of the present invention is steady; The applicant thinks, dibutyl phthalate, diethylene glycol dibenzoate and octanol, Virahol four kinds of components constitute synergistic small system together, specificly can meet the particular requirement that polyvinyl acetate (PVA) and vinyl acetate react in conjunction with polyvinyl alcohol as compound material, not only achieve reaction system steady, do not use the remarkable efficacy of defoamer, effectively can also promote the bond properties of glue, for indexs such as promoting the cohesive strength of final glue and set time, there is direct action effect.
Allyl methacrylate(AMA), ethyleneglycol dimethyacrylate and tolylene diisocyanate have the effect of tackiness agent, applicant selects this 3 kinds of materials dexterously, in conjunction with specific ratio, form synergy system, add in preparation technology's system in the suitable time, very considerably enhance the over-all properties of final glue, and bad impact is not produced on the stability of glue, because the time joining reaction system is last, therefore do not make the preparation technology of glue become more complicated yet, there is significant technical progress.Meanwhile, this area general knowledge, under normal circumstances in rational scope, the higher then result of use of concentration of glue is better, and for reducing costs, glue concentration prepared by a lot of manufacturer is only about 40%, and should be normally about 50-60%; After glue dilution, its moisture content improves, and in use, the moisture that glue contains can infiltrate ligneous piece, and wood is expanded, and causing between ligneous piece cannot be in conjunction with, causes serious product quality problem generation.Therefore, for the object improving the market competitiveness, its result of use and like product can also be kept to maintain an equal level while rationally reducing finished product glue concentration, there is huge marketable value undoubtedly.Glue prepared by the present invention is when being diluted to the degree of market like product, relevant cohesive strength, set time, water tolerance etc. are known and are significantly better than like product, this improves the competitiveness of product in market of the present invention greatly, there is huge marketable value, applicant analyzes, this and in system of the present invention, employ " dibutyl phthalate, diethylene glycol dibenzoate and octanol, Virahol " and " allyl methacrylate(AMA), ethyleneglycol dimethyacrylate and tolylene diisocyanate " these 2 special synergistic combination have vital contact, these 2 collaboration systems not only can promote the adhesive property of glue respectively, combine, further delicate synergy can also be there is, the adhesive property of further raising glue, significantly increase the market competitiveness that the present invention prepares glue.
The experiment effect of associative list 1, although the indices of embodiment 1-5 is all better than comparative example 1, but also difference to some extent between embodiment 1-5, analysis is got off, implement the most preferred embodiment that 5 are the present invention, visible, the content of component selects also there is vital impact, so novelty of the present invention is also embodied in the content selection aspect of each component simultaneously for the final performance of index glue.
Certainly, because the mentality of designing of glue of the present invention and the requirement of goal of the invention, it is also non-obvious that all the other compositional selectings of the present invention and content are selected obviously, and those skilled in the art can expect easily in conjunction with prior art absolutely not.This has further embodiment in the preparation technology of glue of the present invention, can see in conjunction with embodiments of the invention, preparation method of the present invention adopts five steps to design, gradation adds raw material in batches, and the per-cent added has special scope, but not adopt disposable the adding of prior art routine, this technique adapts with the special proportioning of glue component of the present invention, only with adopting this technique, the smooth sequential of guarantee reaction system carries out, and guarantees the superior quality finally preparing glue.
The paste viscosity of waxy corn starch itself is higher, and mobility is poor, and usability is poor; The present invention adds waxy corn starch and clorox with suitable ratio simultaneously in the composition, utilizes hypochlorite oxidation waxy corn starch, forms Sumstar 190, and stick with paste viscosity and reduce, mobility improves; The present invention simultaneously with the addition of N hydroxymethyl acrylamide; Applicant finds, adds waxy corn starch simultaneously, after clorox and N hydroxymethyl acrylamide, significantly can promote the over-all properties of glue further, the cohesive strength of glue and set time index be significantly improved, over-all properties improves further; Applicant thinks, N hydroxymethyl acrylamide is rich in reactive methylol, effectively can promote the degree of adhesion of system; The Sumstar 190 that waxy corn starch changes into has good mobility and stronger anti-shear stability, can promote the fusion of N hydroxymethyl acrylamide in system of the present invention further, and then the lifting of Promotion system degree of adhesion; Meanwhile, Sumstar 190 itself also has sticks with paste viscosity preferably, also can play the effect of tamanori, promotes the adhesive capacity of system; In the process that Sumstar 190 and N hydroxymethyl acrylamide move in system, also can mutually bond, the adhesive capacity of further lifting system; Visible, the present invention is ingenious be make use of waxy corn starch and changes the characteristic that Sumstar 190 has into, not only achieve the effect of enhancing system bounding force, effectively can also promote effect of N hydroxymethyl acrylamide, also can occur to interact and bond with N hydroxymethyl acrylamide, the collaborative integrated bond ability improving system, achieves beyond thought technique effect.Because waxy corn starch itself is comparatively stable, therefore the present invention adopts waxy corn starch as raw material, is convenient to store and transport.
In sum, waxy corn starch compositions of additives of the present invention significantly can promote the performance of glue.Make glue at thermal stability, just the dry time, water resistance, cohesive strength and set time etc., index had outstanding representation, and over-all properties is superior, can meet the strict demand of high-grade energy-conservation wooden doors and windows quality.
