Abstract
A soft polyurethane foam plastics containing filler is made up by adding calcium salt and plasticizer to existing soft polyurethane foam plastics and includes such steps as mixing polyether, calcium salt and plasticizer, grinding to 800-1000 meshes, mixing the emulsion with silicon oil, stannous octoate, triethylenediamine, dichloromethane and water, then addition of isocyanate, stirring for 4-6 seconds, and foaming in mould to obtain the product. It features the cost decreased by 20-30%, density increased by 20-30%, compression load raised by 10-20%, resiliency increased by 8-15%, high qualified product rate, and good product consistence.
Description
The flexible urethane foam that contains filler belongs to the modification and the manufacturing technology thereof of plastics.
The compression load of existing flexible urethane foam and the requirement that rebound resilience does not satisfy some purposes, if improve these performances, present method is the raw materials that drop into more, and the cost of porous plastics is improved greatly, the client is difficult for accepting.
The objective of the invention is to develop a kind of under the prerequisite that reduces existing flexible urethane foam cost, can improve its compression load and the flexible urethane foam that contains filler of rebound performance again.And provide its manufacture method.
The present invention includes polyethers, isocyanic ester, silicone oil, stannous octoate, triethylene diamine, methylene dichloride, water, it also includes calcium salt, softening agent, and they respectively account for following ratio by weight percentage: polyethers 37～60, isocyanic ester 29～40, silicone oil 0.8～1.2, stannous octoate 0.15～0.19, triethylene diamine 0.09～0.11, methylene dichloride 2.4～11.2, water 0.6～3.7, calcium salt 6～15, softening agent 0.3～1.1.Available barium salt, fossil meal replace calcium salt.Calcium salt can be selected lime carbonate, calcium sulfate, calcium chloride etc. for use.Barium salt can be selected barium sulfate, barium carbonate, bariumchloride etc. for use.Softening agent can be selected dioctyl phthalate, phthalic acid dibutyl ester etc. for use.
Its manufacture method is: with polyethers, calcium salt, softening agent add in proportion have agitating function the jar in stir.Slowly put into grinding machine for grinding by valve control, granularity is ground to 800～1000 purpose emulsion puts into agitation vat again, adding silicone oil, stannous octoate, triethylene diamine, methylene dichloride, water in proportion in this bucket then stirs, in this bucket, add isocyanic ester again after waiting to stir, in 4～6 seconds of restir, this compound poured into foam in the mould.
The density of flexible urethane foam of the present invention improves 20%～30% than the flexible urethane foam that reason has, and compression load improves 10%～20%, and rebound resilience improves 8%～15%, and cost reduces by 20%～30%.Its manufacture method yield rate height, the product unanimity is good.
Embodiment one: the flexible urethane foam that contains filler of present embodiment is made up of polyethers, isocyanic ester, silicone oil, stannous octoate, triethylene diamine, methylene dichloride, water, lime carbonate, dioctyl phthalate.They respectively account for polyethers 48, isocyanic ester 30, silicone oil 1, stannous octoate 0.16, triethylene diamine 0.10, methylene dichloride 6, water 2, lime carbonate 12, dioctyl phthalate 0.74 by weight percentage.
Embodiment two: get in the jar that polyethers 48kg, barium sulfate 12kg, dioctyl phthalate 0.74kg join agitating function, stir.Slowly put into grinding machine for grinding by valve control, be ground to 900 orders, this emulsion is put into agitation vat again.Restir is even add silicone oil 1kg, stannous octoate 0.16kg, triethylene diamine 0.10kg, methylene dichloride 6kg, water 2kg in this bucket after, adds isocyanic ester 30kg again in this bucket, in 5 seconds of restir, this compound is poured into foaming gets final product in the mould.Temperature should be advisable at 20～25 ℃ when stirring.
