Description
Technical field
The present invention relates to the preparation method of a kind of sponge, be specifically related to a kind of thermally insulating sponge and preparation method thereof.
Background technology
Sponge product is popularized gradually in people's life, the household objects such as seat, sofa, mattress wherein having sponge to make, polyether glycol is the main raw material producing polyurethane sponge, existing polyurethane sponge is produced the general polyether glycol adopted and is usually adopted petroleum-type polyether glycol, but the stabilized polyurethane that petroleum-type polyether glycol is made is high, be difficult under state of nature decompose; Make it not have degradability, be unfavorable for environment protection and Sustainable development, along with the expansion of the Application Areas of sponge product, the sponge supply that market demand is a large amount of, because existing sponge exists a lot of performance deficiency, uses sponge just to there is potential safety hazard.
Summary of the invention
The object of the present invention is to provide a kind of thermally insulating sponge and preparation method thereof.
The present invention adopts following technical scheme to achieve these goals:
A kind of thermally insulating sponge, it is characterized in that the weight part of its constitutive material is: polyethers glycerol 90-100, isophorone diisocyanate 60-65, nano-ceramic powder 8.0-10.0, zinc acetate 0.1-0.3, tributyl citrate 3-4, trolamine 0.4-0.6,4,4 '-OBSH 3.0-4.0, tween 80 1.3-1.8, modified Nano silicon sol 4-5 and water 6.0-7.5;
The preparation method of described modified Nano silicon sol is: 15-20 weight parts water is added reaction vessel, is heated to 70-80 DEG C; Get 2-3 weight account polyethylene alcohol to be added to the water, stirring and dissolving, then add 0.1-0.15 weight part nano aluminum nitride powder, 1.2-1.3 weight part morpholine, 1-1.2 weight part Nano silica sol, 1-2 parts by weight of acrylic acid, stir, be cooled to 20-30 DEG C, add the Sodium Persulfate of 0.2-0.3 weight part, stir, reaction 30-45 minute, then, add 1-2 weight part silane resin acceptor kh-550,0.1-0.2 weight part Flos Rosae Rugosae quintessence oil again, continue stirring reaction 45-60 minute, to obtain final product.
The preparation method of described thermally insulating sponge, it is characterized in that first the polyethers glycerol of above-mentioned formula ratio, isophorone diisocyanate, modified Nano silicon sol being dropped in mixing tank and mixing, stir, and be heated to 35-45 DEG C, again other remaining component of above-mentioned formula ratio is dropped in mixing tank and mix, pour mould after high-speed stirring 3-5 minute into foam and after solidifying, obtain anticorrosion sponge.
Modified Nano silicon sol of the present invention can make Flos Rosae Rugosae quintessence oil fragrance keep lastingly, meanwhile, increases intensity and the molecular adhesion power of sponge.
Beneficial effect of the present invention:
The present invention with polyethers glycerol and isophorone diisocyanate for major ingredient, there is the feature of excellent flexibility, elasticity, water-absorbent, water tolerance, nano-ceramic powder is high temperature resistant, thermal conductivity is low, adopt nano-ceramic powder to the glycerol modified process of polyethers, improve the performance of product, enhance the heat insulation and preservation effect of sponge.
