Description
Technical field
The present invention relates to the preparation method of a kind of sponge, be specifically related to a kind of water-tight corrosion-proof sponge and preparation method thereof.
Background technology
Sponge product is universal gradually in people's life, wherein there are the household objects such as seat that sponge makes, sofa, mattress, polyether glycol is the main raw material of producing polyurethane sponge, existing polyurethane sponge is produced the general polyether glycol adopting and is conventionally adopted petroleum-type polyether glycol, yet the stabilized polyurethane that petroleum-type polyether glycol is made is high, under state of nature, be difficult to 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, a large amount of sponge of market demand is supplied with, and because existing sponge exists a lot of performance deficiencies, uses sponge just to have potential safety hazard.
Summary of the invention
The object of the present invention is to provide a kind of water-tight corrosion-proof sponge and preparation method thereof.
The present invention adopts following technical scheme to achieve these goals:
A kind of anticorrosion sponge, the weight part that it is characterized in that its constitutive material is: polyoxy tetramethylene glycol 100-110, diphenylmethanediisocyanate 60-70, ultra-fine barium sulfate 13-15, propylene glycol 0.5-0.7, Whitfield's ointment 1-2, dimethyl silicone oil 0.45-0.55, N, N-dinitrosopentamethylene tetramine 5.0-6.0, fatty alcohol-polyoxyethylene ether 2.0-2.5, modified Nano silicon sol 3-4 and water 7.0-9.0;
The preparation method of described modified Nano silicon sol is: 15-20 weight parts water is added to reaction vessel, be heated to 70-80 ℃; Getting 2-3 weight account polyethylene alcohol is added to the water, stirring and dissolving, then add 0.1-0.15 weight part nano silicon nitride aluminium 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 ℃, the Sodium Persulfate that adds 0.2-0.3 weight part, stirs, reaction 30-45 minute, then, add again 1-2 weight part silane resin acceptor kh-550,0.1-0.2 weight part Flos Rosae Rugosae quintessence oil, continue stirring reaction 45-60 minute, obtain.
The preparation method of described water-tight corrosion-proof sponge, it is characterized in that first the polyoxy tetramethylene glycol of above-mentioned formula ratio, diphenylmethanediisocyanate, modified Nano silicon sol being dropped in mixing tank and being mixed, stir, and be heated to 35-45 ℃, again other remaining component of above-mentioned formula ratio is dropped in mixing tank and mixed, high-speed stirring 30-50 pours mould into and foams and solidify after second after, 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:
It is major ingredient that polyoxy tetramethylene glycol and diphenylmethanediisocyanate are take in the present invention, has the feature of good flexibility, elasticity, water-absorbent, water tolerance, has improved the performance of product, has strengthened flavouring, the preservative effect of sponge.
