Abstract
The present invention relates to a production technology of polyurethane foam cushion materials, particularly to a production technology of cushion materials used for improving the riding comfort of chairs of automobiles, trains, airplanes, etc. The present invention adopts a polyurethane foam foaming production technology using polylol and cyanic acid ester as main chemical compositions, and materials are compounded and premixed, namely that more than two kinds among raw materials are firstly mixed and stirred uniformly. Adhesive properties and associative properties among molecules of the materials are reinforced by heat preservation and preheating, and accordingly, the properties of extensibility, elasticity, etc. of products are greatly improved; the products have the advantages of good resilience, high bearing capacity and favorable shock absorbing capacity. The production technology of the present invention has the advantages of simplicity and low cost.
Description
Affiliated technical field
The present invention is about the production technique of polyurethane foam pad material, particularly the production technique of the pad material of the raising riding comfort of using about seats such as automobile, train, aircrafts.
Background technology
Foam pad material is widely used in aspects such as the various vehicles such as automobile and sofa, furniture, sports pad material, to improve soft comfortableness, the seat cushion that surely belongs to all kinds of vehicles such as automobile of consumption maximum wherein, it is produced and generally adopts the main of widespread use is the polyurethane foam production technology of synthetics with polyvalent alcohol and isocyanic ester.Usually seat cushion is comfortable, be soft more good more, but too softness is also uncomfortable.Because the requirement of the vehicles, seat cushion can not be too soft, and the phase cross-demand has resilience preferably and bearing capacity, to strengthen shock-absorbing capacity.Current various product, the softish resilience is poor, and the load that resilience is good is poor, and the rebound resilience flexibility that bearing capacity is good is poor, and these several performances are difficult to comprehensive preferably.Minute quantity product such as imported product are arranged, though over-all properties is better, complex manufacturing, cost height.
Summary of the invention
It is simple to the purpose of this invention is to provide a kind of production technique, and cost is low, the process for producing high loading fire-retarded foamed polyurethane cushion material of good combination property.
Technical scheme of the present invention is: adopting with polyvalent alcohol and isocyanic ester is the polyurethane foam foam production technology of main synthetics, batching is closed in advance, be about in the starting material two or more raw materials by weight mixing earlier and stirring, close material in advance and 1. be polyether glycol (PPG) 50%-60%, isocyanic ester 40%-50%; Close material in advance and 2. be silicone oil 15%-20%, polyether glycol 40%-50%, organophosphorus ester flame-proof agent 35%-50%; Close material in advance and 3. be amine catalyst 30%-40%, stannous octoate 5%-10%, starch 55%-65%; More than each closes in advance and expects that thorough mixing stirs separately, respectively through 25 ℃-30 ℃, be incubated after 10-24 hour, 1. each is closed material in advance expects 75%-85% by weight closing in advance, closes and expect 2. 5%-15%, close and expect that 3. the 10%-20% remix stirs 5-13 second in advance in advance, cast at last, the 5-10 minute shaping and demoulding in cast back.
By closing stirring in advance, cohesiveness, associativity strengthen between material molecule, and performances such as product stretchiness, elasticity all improve a lot.
Owing to adopt and to close technology in advance, and through heat-insulation preheating, the product performance of production are improved a lot, and the raw material that is adopted is common raw material, and cost is low.
Embodiment
With an embodiment the present invention is described below.Adopt polyvalent alcohol and isocyanic ester to close in advance for batching, being about in the starting material two or more raw materials mixes earlier and stirs, close material in advance and 1. be polyether glycol (PPG), adoptable model has 5613,3010,36/28 etc., and the isocyanic ester available model is tolylene diisocyanate (TDI), polyphenyl polyisocyanate (PAPI);
Close material in advance and 2. be silicone oil, adoptable model has L580,2370, and the adoptable model of polyvalent alcohol has 565B etc., and the adoptable model of fire retardant has alkyl halide poly phosphate, di(2-ethylhexyl)phosphate chloropropionic acid etc.;
Close material in advance and 3. be amine catalyst, as triethylene diamine, can adopt model is A33, A-1, and metal catalyst is a stannous octoate, and adoptable model has T9, and linking agent is polyol such as starch etc.;
More than each closes in advance and expects that thorough mixing stirs separately, respectively through 25 ℃-30 ℃, be incubated after 10-24 hour, each is closed material in advance mixes and stir 5-13 second cast at last, the 5-10 minute shaping and demoulding in cast back.
Each raw material consumption adds by above-mentioned weight percentage ranges.
Other is by the routine requirement operation of polyurethane foam.
Claims (1)
1. process for producing high loading fire-retarded foamed polyurethane cushion material, employing is the polyurethane foam foam production technology of main synthetics with polyvalent alcohol and isocyanic ester, it is characterized in that: batching is closed in advance, be about in the starting material two or more raw materials by weight mixing earlier and stirring, close material in advance and 1. be polyether glycol (PPG) 50%-60%, isocyanic ester 40%-50%; Close material in advance and 2. be silicone oil 15%-20%, polyether glycol 40%-50%, organophosphorus ester flame-proof agent 35%-50%; Close material in advance and 3. be amine catalyst 30%-40%, stannous octoate 5%-10%, starch 55%-65%; More than each closes in advance and expects that thorough mixing stirs separately, respectively through 25 ℃-30 ℃, be incubated after 10-24 hour, 1. each is closed material in advance expects 75%-85% by weight closing in advance, closes and expect 2. 5%-15%, close and expect that 3. the 10%-20% remix stirs 5-13 second in advance in advance, cast at last, the 5-10 minute shaping and demoulding in cast back.
