Abstract
The invention discloses an incubator box body which is composed of a double-plastic case body and a middle heat insulation layer; the material of the case body is linear low-density polyethylene processed by adopting rotational molding technology. The incubator box body is characterized in that: the middle heat insulation layer adopts improved polyurethane and changes the chemical property of the stabilizer and catalyst by nano-technology; the filling proportion of the stabilizer is increased to shorten the non-viscous time during foaming process to lead the polyethylene to be tightly agglutinated with the case body. The incubator box body does not change the structure and processing method of the original incubator box body and obviously improves the binding fastness of the case body and the heat insulation layer by the modified design, thus effectively overcoming the disadvantages of the original products of easy-deformed outer wall, hollow interior and unstable heat insulation performance.
Description
Technical field
The present invention relates to insulation can, particularly the casing of insulation can.
Background technology
The basic structure of thermal insulation box body is: the double-layer plastic thin sheet casing is filled with plastic foam heat-insulation and heat-preservation material in the middle of crustless sandwich.Wherein the double-layer plastic thin sheet casing adopts linear low density polyethylene to be processed into through rotational molding technique mostly, and the heat-insulation and heat-preservation material adopts hard polyurethane foam mostly.
Because behind the linear low density polyethylene material rotation molding, smooth surface, make to be filled between hard polyurethane foam in the crustless sandwich and the housing and be difficult to close adhesion, therefore when temperature change is big, air in the isocyanurate foam produces the effect of expanding with heat and contract with cold, and froth bed and plastics wooden partition will be broken away from, thereby causes the distortion of thermal insulation box body outer wall, inner hollow influences the outward appearance and the heat-insulating property of product.
Summary of the invention
The purpose of this invention is to provide a kind of thermal insulation box body, the shell of this casing combines with insulating firmly, stablizes.
Technical scheme of the present invention is:
A kind of thermal insulation box body, be made of double-layer plastic body skin and middle insulating, the material of body skin is a linear low density polyethylene, adopts rotational molding technique processing, it is characterized in that: insulating adopts the polyurethane through modification in the middle of described, and the content of its composition of raw materials and each composition is:
Polyalcohol polyether 200KG
Glycerin polyether 200KG
Amine polyethers 150KG
Low hydroxyl value polyethers 150KG
Stabilizer 40KG through nanotechnology treatments
Amines catalyst 50KG through nanotechnology treatments
Water 7KG.
Above-mentioned urethane raw Formula Design thinking is to change the chemical property of stabilizer and catalyst by nanotechnology; Increase the pan feeding ratio of stabilizer,, make polyurethane and body skin close adhesion to shorten the not sticking time of foaming process.
The present invention does not change the structure and the job operation of original thermal insulation box body, by modification design to polyurethane, obviously improved the combine fastness of cabinet shell, overcome effectively that the existing product outer wall is yielding, inner hollow, the unsettled defective of heat-insulating property with insulating.
Description of drawings
Fig. 1 is the structural representation of thermal insulation box body of the present invention.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
As shown in Figure 1, thermal insulation box body is made of double-layer plastic body skin 1 and middle insulating 2, the material of body skin is a linear low density polyethylene, adopt rotational molding technique machine-shaping, middle insulating is after above-mentioned urethane raw prescription is mixed, and adopts rotation rolling plasticizing process to inject the foaming of body skin cavity and forms.
