Embodiment
Below by specific embodiment, describe content of the present invention in detail.
According to the foaming stock solution composition proportion described in table 1, batching is prepared raw material, then according to the order of addition(of ingredients) of polyhydric alcohol composition, catalyzer, foam stabilizer, water, fire retardant, polymeric polyisocyanate, each raw material is progressively added in mixing vessel, limit is reinforced, limit stirs, and the temperature of the foaming stock solution mixing is maintained to 30 ℃; By the preheating temperature to 50 of foaming mould ℃, under atmospheric pressure the foaming stock solution mixing is injected subsequently to the die cavity of foaming mould, after injection completes, start immediately foaming, sclerosis, and implement instant release of pressure after foaming 90s, make the pressure decreased 0.1MPa in die cavity; After foaming finishes, the foam material obtaining is placed to 24h and obtain final polyurethane foamed material.The properties that test obtains is referring to table 1.
Table 1
Above embodiment 1-3 and comparative example 1#-5# test, ventilation property, theoretical density, damp and hot compression set adopt JIS K6400 method, resonant frequency, resonance multiplying power adopt JACOB407 method, and after flame retardant resistance evaluation adopts flame calcination 30s ignition-material, material is from the time of putting out.
Polyethylene glycol-ester block copolymer all has material impact for the foaminess of polyurethane foamed material in the present invention, intensity, ventilation property etc., in order to guarantee enough foaminess and intensity, its weight part at least should reach 40 parts, and for fear of the inhibition for bubble connectionization to obtain excellent permeability, require its content Ji will exceed 50 parts.Meanwhile, preferably the weight content of its polyester block, between 25-35%, exceedes the 35% hydrolysis property variation that can cause system, lower than 25% Ji can effectively bring into play the excellent breathability of polyethylene glycol-ester block copolymer.In addition, in order to obtain better intensity and weather resistance, should guarantee that its average functional group number is greater than 3, hydroxyl value is greater than 40mgKOH/g, and average functional group's number and hydroxyl value Ji should be excessive, otherwise can reduce extension property etc.
Ethylene oxide-propylene oxide block copolymer can active balance system permeability and vibration performance, in order to bring into play its effect, its content at least should reach 40 parts, but for fear of too much increase setting time, should control its content and be less than 50 parts.Meanwhile, in order to obtain excellent permeability, wish that the content of its oxyethane is at least 40%, but too much ethylene oxide content can cause the tendency of independent whipability too high, and cause the deterioration of extension property, ventilation property etc.In addition, be proof strength and weather resistance, should make its average functional group number be greater than 2, hydroxyl value is greater than 100mgKOH/g, and average functional group's number and hydroxyl value Ji should be excessive, otherwise can reduce extension property, extend setting time etc.
Polyoxyethylene glycol has higher separated foam tendency, improves the weather resistance of system, and for bringing into play above-mentioned effect, the content of polyoxyethylene glycol at least should be 5 parts, but its content also Ji should be too high, otherwise can cause the deterioration of extension property, ventilation property.Meanwhile, its average functional group number is more than 3, and hydroxyl value can improve intensity and weather resistance more than 400mgKOH/g, and average functional group's number and hydroxyl value Ji should be excessive, otherwise can reduce extension property, extends setting time etc.
For guarantee system has enough intensity and endurance quality and good vibration performance, in polymeric polyisocyanate, the content of tolylene diisocyanate should be at least 30%, but from environment equal angles, consider that therefore the use tolylene diisocyanate of preferably trying one's best few is controlled its content and be 50% and think.In addition,, when meeting 2,4 toluene diisocyanate/2, during 6-tolylene diisocyanate=2:1, material has more excellent permeability.
In foam stabilizer, select L626 type silicone oil can obtain the effect of obvious bubble connectionization, thereby without excessive physical disturbance with produce continuous air bubbles, to avoid the destruction of foam interior, for bringing into play its effect, its addition should exceed 0.02 part, but its addition must strictly be controlled, otherwise may cause bubble homogeneity variation, thus the weather resistance of reduction foam materials etc.
In order to bring into play enough fire retardations, the content of fire retardant should exceed 10 parts, but its content Ji can be too high, otherwise can cause the deterioration of the performances such as the intensity, rebound resilience of material system.Find, the composite fire retardant of condensed phosphoric acid esters and melamine resin can be brought into play fire retardation to greatest extent, and preferably its ratio is 2:3 simultaneously.
The polyurethane foamed material that the present invention is prepared is cut to specified dimension, then respectively on its surface with the coated nonwoven layer of binding agent and leather layer, can obtain the present invention and have the automobile cushion of excellent properties.
