Abstract
The invention discloses a kind of preparation method of EPE foam pad mattress, comprise the steps: (1) raw material impregnation precompressed: EPE foam particle is carried out impregnation precompressed, then carries out pressurize, be finally depressurized to atmospheric pressure; Obtain EPE foam particle raw material; (2) injection mo(u)lding: the EPE foam particle raw material adopting above-mentioned steps (1) to obtain carries out injection mo(u)lding, obtains initial EPE foam pad mattress; (3) post processing: above-mentioned initial EPE foam pad mattress is put into confined chamber and toasts, EPE foam pad mattress can be obtained.This invention exploits a kind of preparation method of new EPE foam pad mattress, before injection mo(u)lding, impregnation precompressed process is carried out to EPE foam particle, the initial EPE foam pad mattress obtained after injection mo(u)lding carries out post processing, experiment proves: the qualification rate of the EPE foam pad mattress obtained according to method of the present invention improves greatly, reach more than 98%, achieve beyond thought effect.
Description
Technical field
The present invention relates to a kind of preparation method of EPE foam pad mattress.
Background technology
Foam pad mattress is also sponge matress, the mattress that main exactly material foam is made.Foam pad mattress can meet the curve of health, while providing support, does not lose softness and elasticity, can cushion the action of health simultaneously, even if a people frequently stands up, also can not have influence on companion, not have noise when standing up.Therefore, foam pad mattress obtains the favor of consumers in general and likes.
Existing foam pad mattress is mainly divided into three kinds: polyurethane foam mattress, elastomeric foam mattress and memory foam mattress.Wherein, what polyurethane foam mattress referred to is exactly memory sponge mattress common on market, also be space memory sponge mattress, low resilience mattress, use when it makes a return voyage cushion to U.S. space astronaut the earliest, the most obvious feature is exactly that resilience is slow, shape can be changed along with the change of pressure, therefore seem that just looking like is the pressure remembering this position, keeps the shape that this has, good laminating body curvature, reduces mattress to the pressure of health.But polyurethane foam is chemical products, in foaming process, have very heavy taste, the requirement of people to environmental protection cannot be met.
For the problems referred to above, there is EPE foam pad mattress, EPE(ExpandablePolyethylene), it is expandability polyethylene, also known as expanded polyethylene foam, it is non-crosslinked hole-closing structure, is the high foamed polyethylene goods generated for primary raw material extruding with low density polyethylene (LDPE) (LDPE).EPE foamed product density is little, pliability good, response rate is high, and have independently bubble structure, absorptivity is low, acidproof, alkaline-resisting, salt, wet goods organic solvent corrosion, and ageing-resistant performance is excellent; And do not pollute the environment, can recycle by repetitiousness, therefore EPE foamed material is a kind of novel, Chaoyang unabated material forever.Along with the propelling of time and product continually develop application, EPE pearl wool expanded material will be applied even more extensively in packaging and filling in materials.
In prior art, EPE foam pad mattress is mainly prepared by injection moulding machine.But actual production process finds, there are the following problems for the EPE foam pad mattress directly prepared by the method for injection mo(u)lding: buckling performance and the load performance of (1) product are poor; (2) product percent of pass is lower, usually about 80%.
Summary of the invention
Goal of the invention of the present invention is to provide a kind of preparation method of EPE foam pad mattress.
To achieve the above object of the invention, the technical solution used in the present invention is: a kind of preparation method of EPE foam pad mattress, comprises the steps:
(1) raw material impregnation precompressed: EPE foam particle is carried out impregnation precompressed, then carries out pressurize, is finally depressurized to atmospheric pressure; Obtain EPE foam particle raw material;
The pressure of described impregnation precompressed is 3.0 ~ 4.0MPa, and the time is 16 ~ 26 hours;
The pressure of described pressurize is 2.5 ~ 3.0MPa, and the time is 3 ~ 3.5 hours;
The time of described step-down is 1.0 ~ 1.5 hours;
(2) injection mo(u)lding: the EPE foam particle raw material adopting above-mentioned steps (1) to obtain carries out injection mo(u)lding, obtains initial EPE foam pad mattress;
(3) post processing: above-mentioned initial EPE foam pad mattress is put into confined chamber and toasts, baking temperature is 80 ~ 85 DEG C, 8 ~ 16 hours time; Then confined chamber was down to room temperature in 6 ~ 16 hours, leaves standstill 12 ~ 24 hours, EPE foam pad mattress can be obtained.
Preferably, in described step (1), the pressure of impregnation precompressed is 3.5MPa.
Because technique scheme is used, the present invention compared with prior art has following advantages:
1. this invention exploits a kind of preparation method of new EPE foam pad mattress, before injection mo(u)lding, impregnation precompressed process is carried out to EPE foam particle, the initial EPE foam pad mattress obtained after injection mo(u)lding carries out post processing, experiment proves: the qualification rate of the EPE foam pad mattress obtained according to method of the present invention improves greatly, reach more than 98%, achieve beyond thought effect.
2. the buckling performance of EPE foam pad mattress that obtains of the present invention and load performance improve all greatly, achieve significant effect.
3. preparation method of the present invention is simple, and cost is lower, is suitable for applying.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described:
Embodiment one:
A preparation method for EPE foam pad mattress, comprises the steps:
(1) raw material impregnation precompressed: EPE foam particle is carried out impregnation precompressed, then carries out pressurize, is finally depressurized to atmospheric pressure; Obtain EPE foam particle raw material;
The pressure of described impregnation precompressed is 3.5MPa, and the time is 16 ~ 26 hours;
The pressure of described pressurize is 2.5 ~ 3.0MPa, and the time is 3 hours;
The time of described step-down is 1.0 hours;
(2) injection mo(u)lding: the EPE foam particle raw material adopting above-mentioned steps (1) to obtain carries out injection mo(u)lding, obtains initial EPE foam pad mattress;
(3) post processing: above-mentioned initial EPE foam pad mattress is put into confined chamber and toasts, baking temperature is 80 DEG C, 8 ~ 16 hours time; Then confined chamber was down to room temperature in 6 ~ 16 hours, leaves standstill 12 ~ 24 hours, EPE foam pad mattress can be obtained.
The EPE foam pad mattress feature specific as follows obtained by said method:
Hardness can reach salient point, four sides, front, and the average hardness at the back side should higher than more than 40HC;
Its thrust can reach and push away in the middle of massage ball, till single ball massage ball fracture, reaches more than 18KG;
Completely, smooth surface, does not have rugged and uneven in foaming, finger press and unclamp after can rapid resilience, reinstatement;
The doubling of long limit, corner is close between two, and mattress bending part is without cracking phenomena, and resilient within a certain period of time after unclamping.
Under the pressure of 18.5kg:
After pressure 8h, product height is not less than 50% of former height;
After pressure 8h resilience 16h, product height is not less than 80% of former height;
After pressure 8h resilience 24h, product height is not less than 90% of former height;
After pressure 8h resilience 72h, product height is not less than 95% of former height.
Comparative example one:
A preparation method for EPE foam pad mattress, comprises the steps:
Adopt the EPE foam particle identical with embodiment one, directly carry out injection mo(u)lding, obtain EPE foam pad mattress.
The matt appearance of the EPE foam pad mattress that it obtains, surface irregularity, rebound effect is poor, and product atrophy, product percent of pass is only about 80%.
