Abstract
The invention provides an adsorption liner structure of a refrigerator, and belongs to the technical field of material process. The adsorption liner structure of the refrigerator solves the problems that an existing mold of a refrigerator liner is high in precision requirement, capital investment is increased, but the weight reducing effect is not achieved, and the heat-preserving efficiency is improved. The adsorption liner structure of the refrigerator comprises a basic layer panel, and a heat-preserving layer is attached to the basic layer panel. According to the manufacturing technology of the heat-preserving layer, foaming agent is added into resin material, the foaming agent is decomposed into N2, CO2 and other gas when being heated, a plurality of gas holes are formed in the resin material by releasing the gas, and the gas holes are closed holes. The adsorption liner structure of the refrigerator has the advantages that the mass of material can be reduced; thermal insulating capacity of the material can be enhanced; the noise insulating effect is achieved; the rigidity and tenacity of the material can be increased; the machining fluidity of the material is optimized; waste of raw materials is avoided, and production cost is saved.
Description
Technical field
The invention belongs to material technology technical field, relate to a kind of foam process, particularly a kind of refrigerator absorption inner-tube structure.
Background technology
Tradition refrigerator absorption inner bag is to be made up of the sheet material of metal material or plastic material mostly.In order to meet the technological requirement of plastic shaping, the material temperature of avoiding technique warm-up phase to cause is unbalanced, the wall of inner container material cracking that moulding forms later or due to the appearance of the problems such as material is bright, when design, generally all adopt the material that safety factor is higher, do not allow as much as possible waste of raw materials.
Current, that most freezer liner has all adopted aspect material is shock-resistant, mobility and the good plastic plate of Toughness Ratio, and equipment aspect is to have adopted the absorption of spill to make mould.Can guarantee like this moulding of inner bag, and the generation of the problem such as less cracking, breakage, not only improve production efficiency, strengthen yield rate, save again a large amount of raw material, reduce the cost of product.Although current freezer liner has adopted the spill adsorption technology of improveing, but the mould and die accuracy that this technological requirement is higher, the manufacturing cost of equipment is corresponding increase also, not only Mould Machining is very difficult, and require input also larger, the risk that has strengthened like this investment has extended return period, is unfavorable for the recovery of fund.The material thickness of design does not also reach the effect of fundamentally weight reduction, so the effect reducing costs is played in still can not be a large amount of save material; And the increasing of equipment funds input, and then risk improves.
Summary of the invention
The object of the invention is to have the problems referred to above for existing technology, proposed one and utilized blowing agent effect, arrive weaker zone inner bag, realize material-saving, light weight, rigidity is strong, toughness is strong, promotes the refrigerator absorption inner-tube structure of heat insulation effect.
Object of the present invention can realize by following technical proposal: a kind of refrigerator absorption inner-tube structure, comprise basic unit's sheet material, it is characterized in that, on described basic unit sheet material, paste heat-insulation layer, the manufacturing process of described heat-insulation layer is, adds blowing agent in resin material, makes blowing agent under heating status, decomposite N2, CO2 gas, form some pores by being released in resin material of gas, described pore is closed cavity.
In this refrigerator absorption inner-tube structure, blowing agent is used on the designing material of inner bag, form thus the highdensity sealed porosity layer of one deck, be weaker zone.This structure not only can lightening material quality, can also improve the rigidity of material, the heat conductivity of reinforcing material.So this technology for liner material, in can improving material property, can also reduce raw-material waste, be after the application trend of environmental protection and energy saving material.
In above-mentioned refrigerator absorption inner-tube structure, in described heat-insulation layer, some pores are honeycomb shape.
In above-mentioned refrigerator absorption inner-tube structure, described blowing agent comprises CBA, physical blowing agent and surfactant.
In above-mentioned refrigerator absorption inner-tube structure, described hole diameter size is directly proportional to blowing agent heating temperature height.
Compared with prior art, this refrigerator absorption inner-tube structure uses blowing agent on the designing material of inner bag, and then formation has the weaker zone of high density sealed porosity, and this inner-tube structure is had the following advantages: the quality that (1) can lightening material; (2) heat-insulating capability that can reinforcing material; (3) play the effect of noise insulation; (4) increase rigidity of material and toughness; (5) optimize materials processing mobility; (6) avoid waste of raw materials, save production cost.
The specific embodiment
Be below specific embodiments of the invention, technical scheme of the present invention is further described, but the present invention is not limited to these embodiment.
This refrigerator absorption inner-tube structure comprises basic unit's sheet material, on basic unit's sheet material, pastes heat-insulation layer.
The manufacturing process of heat-insulation layer is: in resin material, add blowing agent, make blowing agent under heating status, decomposite the gas such as N2, CO2, gas forms bubble in resin material, and then in resin material, form some pores by being released in of gas, make heat-insulation layer form the weaker zone with high density sealed porosity after cooling.
Each pore in weaker zone is closed cavity, and overall air hole structure is honeycomb shape.
In the process of foam process, hole diameter size is directly proportional to blowing agent heating temperature height.Can pass through temperature control accurately, obtain the size of pore in required weaker zone, and then form the enclosure space that a large amount of inside is connected.
Blowing agent comprises CBA, physical blowing agent and surfactant.
In this refrigerator absorption inner-tube structure, blowing agent is used on the designing material of inner bag, thus by the optimization moulding to freezer liner sheet material technique, improve as after thering is the liner material structure of the micro-pore weaker zone of high density by original one deck plastic material, high light high-density layer can ensure the refinement degree on inner bag surface, form and increased pore foaming layer the enclosure space that a large amount of inside is connected, played the effect of falling low heat conductivity convection efficiency, thereby can improve heat-insulating property.Through the forming double-layer inner-tube structure of improved process processing, can better guarantee the quality of inner bag, and in having adopted micro-pore technique, make in situation that material thickness is identical, weight is lighter, has improved raw-material utilization rate, save cost, and improved the heat-proof quality of product.Above-mentioned these factors can improve the industrial competition of product.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit.Those skilled in the art can make various modifications or supplement or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present invention or surmount the defined scope of appended claims.
