2) adjust PH to 4-5 with 20% formic acid, add plant essence 1-10 part and be warming up to 90-95 DEG C;
3) add 30% sodium hydroxide and adjust PH to 5.5-6.0, be cooled to 80 DEG C and add second time urea 10-15 part, insulation 10-20 minute; Continued down to 60 DEG C adds third time urea 5-10 part, and namely 40 DEG C of blowings obtain environment-friendly type natural plant fragrance aminoresin;
Described part is weight part.
Described step 3) frontly need sample detection, there is white mist in glue sample of getting, pH5.5-6.0 can be adjusted to stop polycondensation in 35-40 DEG C of water.
The preparation method of environment-friendly type natural plant fragrance aminoresin, carries out according to the following steps:
The glue that routine makes is added plant essence by the part by weight of 1-5%, and mix and blend is for subsequent use after 10 minutes.
Described plant essence extracts from the plant of natural scents; Described plant is Stigma Croci, lavandula angustifolia, thyme, Rose, the one stayed in indigo plant, apple, Salvia japonica Thunb., peppermint.
The preparation method of environment-friendly type natural plant fragrance aminoresin, carries out according to the following steps:
By stand-by vegetable material, be placed on immersion in the conventional glue made by the part by weight of 5-10% and, after 2 hours, after being filtered by glue, modulate use.
Described vegetable material is the plant with natural scents; Preferred Stigma Croci, lavandula angustifolia, thyme, Rose, the one stayed in indigo plant, apple, Salvia japonica Thunb., peppermint.
The invention has the beneficial effects as follows:
Aminoresin provided by the invention, be by extract in plant volatile aromatised fraction or and mixture, by with resin copolymerization or mix.Utilize fragrance ingredient and detoxicating functions of reposing in component, from source, the Volatilized smell of chemical resin is carried out decomposition composition, change the smell structure of conventional resins, do not affect using function again, thus create lighter and comfortable Working environment, improve the working efficiency of staff, impregnation can be widely used in, overlay industry.
Embodiment
The present invention does in process in the amino resin-made of low formaldehyde, add a kind of natural plant material in the proper ratio and aminoresin blended, the natural plant material making this kind have active group can keep the original characteristic of resin, the smell structure of aminoresin can be changed again, flood and overlay burst size of methanal in process be up to state standards at resin formulations, decorative paper, production plant also gives out light natural scents simultaneously, and operator feel comfortable; For impregnation industry Green Development provides new solution.
Key problem in technology is:
(1) by shaker test, the natural plant material that selectivity is stable, makes itself and resin have good consistency;
(2) by the research and design that there is the natural plant material blending ratio of active group to several and and resin is confluent researchs and analyses, make its with resin alloy after, light natural phant fragrance can be given out, at dipping with overlay in process and guarantee not change original resin property, can not negative effect be produced, thus improve Working environment.
