Abstract
The invention adopts the following technical scheme that the invention relates to a production ratio of a novel formaldehyde-free adhesive. The production ratio comprises polyvinyl alcohol 1, modified starch 2 and glyoxal 3, and is characterized in that the dosage of polyvinyl alcohol 1 of the production ratio of the novel formaldehyde-free adhesive is 0.38t. The production ratio has the advantages that a product replaces traditional high-pollution methanal with low-pollution glyoxal to serve as a raw material; and the adhesive is novel and environment-friendly.
Description
Technical field
The present invention relates to a kind of novel no-formaldehyde adhesive producting proportion, belong to field of fine chemical.
background technology
Resol english abbreviation is PF, because having high, water-fast, heat-resisting, the wear-resisting and good chemical stability of cohesive strength, is widely used in timber industry.In the U.S., Japan and some European countries' timber industries, the consumption of synvaren is more than the twice of urea-formaldehyde resin adhesive.Less at the consumption of China's Phenol aldehyde resin, the tackiness agent more than 80% that timber industry uses is urea-formaldehyde resin, so synvaren is very large in the potentiality to be exploited of China, should actively to production principle and the technique of tackiness agent resol, equipment launches research further, so that further extensive, large suitability for industrialized production.In addition, synvaren also also exist that color is dark, firmly crisp, the easy be full of cracks of glue-line after solidification, the cost shortcomings such as comparatively urea-formaldehyde resin adhesive is expensive, toxicity is larger.Particularly high, the curing speed of synvaren solidification value slow (generally will hot pressing just can obtain at 130 ~ 150 DEG C bonding strength), cause production efficiency low, energy and devices consume greatly, limit synvaren and apply widely.
Summary of the invention
Object of the present invention overcomes the deficiency of above technology, provides a kind of novel no-formaldehyde adhesive producting proportion.Be achieved through the following technical solutions for achieving the above object: the present invention relates to a kind of novel no-formaldehyde adhesive producting proportion, comprise polyvinyl alcohol 1, treated starch 2, oxalic dialdehyde 3 form, it is characterized in that the throwing amount of the polyvinyl alcohol 1 of described a kind of novel no-formaldehyde adhesive producting proportion is 0.38 ton.The throwing amount of the treated starch 2 of described a kind of novel no-formaldehyde adhesive producting proportion is 0.39 ton.The throwing amount of the oxalic dialdehyde 3 of described a kind of novel no-formaldehyde adhesive producting proportion is 0.21 ton.
advantage of the present invention is:
Product instead of the formaldehyde of traditional high pollution as raw material using oligosaprobic oxalic dialdehyde, is a kind of tackiness agent of novel environment friendly.
embodiment explanation
tell about embodiment below:
embodiment 1:a kind of novel no-formaldehyde adhesive producting proportion:
The present invention relates to a kind of novel no-formaldehyde adhesive producting proportion, comprise polyvinyl alcohol 1, treated starch 2, oxalic dialdehyde 3 form, it is characterized in that the throwing amount of the polyvinyl alcohol 1 of described a kind of novel no-formaldehyde adhesive producting proportion is 0.38 ton.The throwing amount of the treated starch 2 of described a kind of novel no-formaldehyde adhesive producting proportion is 0.39 ton.The throwing amount of the oxalic dialdehyde 3 of described a kind of novel no-formaldehyde adhesive producting proportion is 0.21 ton.
Certainly; above-mentioned explanation is not limitation of the present invention; the present invention is also not limited in above-mentioned citing, the change that those skilled in the art make in essential scope of the present invention, remodeling, interpolation or replacement, also should belong to protection scope of the present invention.
