Abstract
The invention discloses a preparation method of an antibacterial type soft polyurethane foaming plastic. The preparation method is characterized by comprising the following technical steps: a, adding metered polyether glycol N330 and 1,4-butanediol, a catalytic amount of dibutyltin dilaurate and tripolycyanamide to a reaction kettle, filling nitrogen or an inert gas into the reaction kettle for protection, heating at 40-60 DEG C, sufficiently stirring for 6-8 hours, and reducing temperature to 25 DEG C; b, adding polyisocyanate, silicone oil, triethylamine, nanometer zinc oxide and a right amount of water to a product obtained from the step a, and stirring at high speed till foaming; c, when a large quantity of white foams appear, immediately injecting the white foams into a mould, aging at 40-60 DEG C for 60-150 minutes, and demoulding to obtain a soft polyurethane foaming plastic product. The obtained polyurethane soft foaming plastic has the advantages of good antibacterial and bactericidal property, stability in heat-resistant property, no bactericide separation, safety, environment protection, simpleness and convenience for production process and suitability for industrialized production.
Description
Technical field
The invention belongs to the urethane foam field, particularly a kind of preparation method of antimicrobial form flexible urethane foam.
Background technology
Flexible urethane foam (abbreviation flexible PU foam) refers to have certain elastic class flexibility urethane foam, and it is a kind of polyurethane products of consumption maximum.The foam structure of flexible PU foam mostly is perforate.Generally have that density is low, elastic recovery good, the performances such as sound-absorbing, ventilative, insulation, main as cushion material, vehicle seat cushion material, various soft liner laminar composite, also soft bubble is used as to filtering material, sound-proof material, packing, finishing material, wrapping material and heat-insulating heat-preserving material etc. on industrial and civilian.Owing to containing bacterium, the necessary nutritive substance of mould in polyurethane material, under suitable temperature and humidity condition, microorganism (bacterium and mould) will amount reproduction, mould secretory product causes the biological degradation of urethane, raising along with people's living standard, have higher requirement to the sanitation performance of material in increasing field, therefore giving porous plastics is necessary with germ resistance.
Normally, prepare the antibacterial and mouldproof porous plastics by add one or more antiseptic-germicides in plastic formula technique, thereby reach the effect of anti-bacteria and mold propagates.The kind of antiseptic-germicide is a lot, comprises aseptic antiseptic-germicide, the large class of organic antibacterial agent two.In inorganic antiseptic, antibacterial effect is silver-series antibacterial agent preferably, have advantages of that thermotolerance is higher, but cost is high, and consumption is relatively large, and easy to change; Synthetic organic antiseptic-germicide has the characteristics such as quick-acting, that anti-mold effect is good, but the characteristics such as it is poor to have thermotolerance, and duration of efficacy is short, easily separates out, and security is low.
summary of the invention:
The objective of the invention is for deficiency of the prior art, provide a kind of fungi-proofing sterilization functional, product properties is stable, and safety and environmental protection is suitable for the preparation method of the antimicrobial form polyurethane soft foamed plastics of suitability for industrialized production.
Technical scheme: for achieving the above object, a kind of preparation method of antimicrobial form flexible urethane foam comprises following technological step:
A, add polyether glycol N330 and the BDO of metering in reactor, the dibutyl tin laurate of catalytic amount, trimeric cyanamide, be full of nitrogen in still or rare gas element is protected, and heats 40 ~ 60 ℃, fully stirs 6 ~ 8 hours, is cooled to 25 ℃;
Add polymeric polyisocyanate in b, the product that obtains at step a, silicone oil, triethylamine, nano zine oxide, suitable quantity of water, high-speed stirring is to foaming;
C, when a large amount of white foam occurring, it is injected to mould immediately, in 40 ~ 60 ℃ of lower slakings 60 ~ 150 minutes, the demoulding, obtained the flexible urethane foam goods.
Described polymeric polyisocyanate is poly-4,4 '-'-diphenylmethane diisocyanate (poly-MDI).
Described organic silicone oil is organic silicon modified by polyether oil SF-8427.
The size of described antiseptic-germicide nano zine oxide is at 50 ~ 250nm.
According to above technical scheme, can realize following beneficial effect: compared with prior art, polyurethane soft foamed plastics that the present invention obtains has the following advantages: the plastics fungi-proofing sterilization is functional, resistance toheat is stable, without sterilant, separate out, safety and environmental protection, production technique is easy, cost is lower, and stability at later stage can be good.
