Abstract
The present invention relates to a polyurethane and polystyrene composite material, mainly used in heat-insulating and decoration trade. Said invented composite material integrates the advantages of polyurethane and polystyrene into one whole, and can utilize waste polystyrene material to benefit the action of controlling white pollution and protecting environment.
Description
The present invention is a kind of matrix material, the foaming of two kinds of materials, compound after, overcome self weakness, brought into play strong point separately, can be used for various insulations, decoration occasions.
Present polyurethane foam and polystyrene foam all are independent foaming, urethane quality softness, good toughness, good springiness, can be used for various decorations and insulation, but heat-insulating property is good not as the polystyrene foam, and the price height, be three times of polystyrene price, and polystyrene foam thermal insulation performance is fine, in light weight, and also has a kind of flame retardant type, can be used for fire-retardant material, but elasticity, flexible poor, can not bending, and depleted polystyrene foam causes white pollution.Because two kinds of materials relative merits separately are to its use range is restricted.
Purpose of the present invention foams two kinds of material mixing exactly together, makes its product can overcome separately shortcoming, performance common advantage, and become the new thermal insulation decorative material of a generation, and can solve the white pollution problems of depleted polystyrene.
The object of the present invention is achieved like this: earlier the polystyrene material is sent out into desired particle size (waste product can be ground into corresponding particle), then these particles are placed the encloses container that leaves pore, in container, inject the urethane raw composition again, it is foamed in container.The polyurethane foam raw material has just been clamp-oned in the slit of polystyrene foam beads like this, as a kind of tackiness agent, the polystyrene particle is sticked together tightly, after the curing, be close between a kind of each polystyrene particle and be full of polyurethane foam between the particle in the slit with regard to having formed, and the goodish a kind of advanced composite material of avidity.
The invention has the advantages that: 1, have only two kinds of material mixing, prescription is simple.2, because the price of urethane is three times of polystyrene price, after two kinds of raw material combinations, price can reduce greatly.3, two kinds of materials compound after, its advantage separately is able to comprehensively.4, utilize depleted polystyrene foam can reduce the white pollution of environment.
Concrete structure embodiment of the present invention is provided by accompanying drawing, and Fig. 1 is the sectional view of polystyrene of the present invention, polyurethane foam composite.
Below in conjunction with description of drawings: 1. being the polystyrene foam beads, is polyurethane foam 2., learns that through test the avidity of two kinds of materials is very good, is a kind of perfect condition product.
Claims (3)
1, a kind of matrix material, be 1. to be that base-material mixes insulation, the finishing material of sending out 2., it is characterized in that: in container, 2. 1. the polystyrene foam beads is wrapped up and gang forms bulk by polyurethane foam with the polystyrene foam beads with polyurethane foam.
2, according to claim 1 described structure, 1. the polystyrene foam must make the particle of certain size earlier.
3, according to claim 1 described structure, send out good polystyrene foam beads and 1. need be placed on earlier in the container that has a venting hole, add 2. component material of urethane then, covered container lid, sealing, allow urethane 2. foam in container, air is discharged by venting hole in the container.
