Description
Technical field
The present invention relates to foam production technical field, particularly to a kind of polyurethane foam combination。
Background technology
Polyurethane is the abbreviation of polyurethanes, and the macromolecular compound of every-NHCOO-group on high polymer main chain containing many repetitions is commonly referred to as polyurethanes.
Polyurethane foam plastics range of application is very extensive, almost penetrate into each department of national economy, use very general in departments such as furniture, bed accessory, transport, cold preservation, building, thermal insulation especially, it has also become one of indispensable material, it has also become one of kind that in plastics, range of application is the widest.
Rigid polyurethane foam refers to and obvious deformation will not occur under certain load effect, then can not return to the foam plastics of original form when load is excessive after deforming；Rigid polyurethane foam, has light weight, a remarkable advantage such as intensity is big, heat-insulating sound-insulating is effective, convenient formation, as door-plate inner stuffing, can be applied to an industry and produce；Hard polyurethane foams raw material has good mobile performance and the adhesive property good with panel, the panel making door is combined closely with polyurethane foam, form the compound door plant of high intensity, it is big that the door-plate so produced has surfacing, intensity, and the heat conductivity of hard polyurethane foams is low, insulation effect is excellent, and can carry out on-the-spot injection moulding door-plate.Therefore, hard polyurethane foams is a kind of ideal door-plate core, and it does compared with door-plate core with refill, has the advantage that
1, compared with doing inserts with common refill, heat preservation and insulation is excellent.
2 and general packing material, soundproof effect is very prominent.
3, the compressive strength of foam is big, the door-plate produced, lightweight, combined strength bination big, plate face is smooth, can stand higher mechanical load.
4, implant water absorption rate is very low, good stability of the dimension, and life-time service will not deform.
5, the ageing-resistant life-span of foam is long, uses for up to more than 30 years.
6, foam is nontoxic, non-corrosiveness.
7, molding is easy, and production efficiency is high, it is easy to large-scale production.
Although hard polyurethane foams has above multiple advantage, but its resistance to elevated temperatures is poor, all can produce obvious tympanites phenomenon more than 120-140 DEG C, and hard polyurethane foams is once deform, then irreversible；Producing polyurethane foam door (by polyurethane foam as door-plate inner stuffing) traditional handicraft is all the technique that after adopting door-plate molding, first plastic-blasting foams again, avoid owing to the high temperature of plastic-blasting operation causes the door body deformation after foaming, foam in foaming process is extruded/is spilt the surface of unavoidable end of door plate and pollutes, have a strong impact on the presentation quality of finished product door-plate, because foam is good with the adhesive property of door-plate, this brings a difficult problem on the contrary later stage cleaning work。
