Abstract
The invention relates to a refrigerator and a magnetic door seal for a freezer. The door seal is a TPE elastomer door sealing glue sheath; the section of the glue sheath is an annular air bag; a magnetic strip passes through the door seal; and the TPE elastomer door sealing glue sheath mainly comprises the following materials: SEBS, PP, PE, CaCO3, white oil, lubricating agent, antioxidant and proper amount of pigment. The invention has the following advantages: when cold gas is spilled out, the cold gas must perform heat exchange with outside air through the air bag outside, which protects the environment and is not easy to be influenced by the environment temperature, thereby greatly decreasing cold quantity loss. The invention greatly improves the sealing effect of door seal and refrigerator and decreases the coefficient of heat transfer, thereby saving energy and having the advantages of decreasing energy consumption, prolonging service life.
Description
Technical field
The present invention relates to magnetic door strip of paper used for sealing technical field, especially a kind of refrigerator, refrigerator magnetic door strip of paper used for sealing.
Background technology
At present, the gasket material that the refrigerator of selling on the market, refrigerator are used, the overwhelming majority is made with flexible PVC, influenced by its material self character, in use and installation process, can have the following disadvantages: (1), resistance to low temperature are poor, will become fragile at PVC gum cover below-25 ℃, and be subjected to the circumstance of temperature difference variable effect quite obvious, temperature variation ± 4 are to 5 ℃, and its hardness just changes ± 1 degree thereupon, so, the temperature in summer and winter influences the sealing property of its door of refrigerator strip of paper used for sealing easily, causes the increase of energy consumption; (2), anti-migration performance is relatively poor, softening agent is moved on the plastic-absorbing component of ABS, HIPS easily in PVC, or on the spraying lacquer painting of refrigerator, thereby causes breaking of plastic-absorbing component, or causes the corrosion trace with spraying face, serious meeting causes adhesion; (3), ageing resistance is poor because flexible PVC is made up of multiple softening agent or subsidiary material because the prolongation of duration of service, its PVC door sealing cover hardening, variable color, aging, thus influence seals and outward appearance, shortens its work-ing life; (4), PVC is the abbreviation of polyvinyl chloride, itself contains vinyl chloride monomer, is halogen-containing plastic material, is divided into non-environmental protection material in the world; (5), because the physical strength of general flexible PVC is little, and fracture enlongation rate is below 200%, tensile strength 8N/MM2 generally was no more than 100,000 times in the switch test life-span of refrigerator, influenced its work-ing life; (6), the elasticity of flexible PVC gasket is relatively poor, processed easily, the various reasons in the packing, warehousing, transportation causes distortion, and cause poorly sealed, run phenomenons such as cold, have a strong impact on the refrigeration of refrigerator, cause energy consumption to improve.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of magnetic door strip of paper used for sealing of TPE material, this magnetic door strip of paper used for sealing is applicable on the refrigeration equipments such as refrigerator, refrigerator, have environmental protection, be not subject to the influence of variation of ambient temperature, can keep good seal performance and elasticity and have cutting down the consumption of energy and advantage such as long service life.
The present invention for the technical scheme that the technical solution problem adopts is:
A kind of refrigerator, refrigerator magnetic door strip of paper used for sealing, described gasket is a TPE elastomerics door sealing cover, the cross section of described gum cover is an annular air-pocket, wears magnetic stripe on gasket, it is characterized in that described TPE elastomerics door sealing cover mainly is made of the raw material of following weight part ratio:
SEBS 46-48 part
PP 7-9 part
PE 2.5-2.9 part
CaCO
39-10 part
White oil 31-34 part
Lubricant 1.1-1.2 part
0.1 part of antioxidant 1010.
Described magnetic door strip of paper used for sealing can also also include an amount of pigment according to using needs in its raw material.
Beneficial effect of the present invention is as follows:
(1), the TPE resistance to low temperature is quite outstanding, resistance to low temperature is below-60 ℃, and be subjected to the influence of envrionment temperature quite little, by 40 ℃ to the 0 ℃ so big temperature difference, the variation of its shore hardness does not almost have, and its feel is still soft under-10 ℃ low temperature, therefore, improve its sealing property widely, reduced energy consumption significantly;
(2), TPE do not have transport property to ABS, HIPS and spray paint, thereby prolonged the work-ing life of gasket and ABS, HIPS plastic-absorbing component, spray paint;
(3), TPE has well anti-aging, anti-UV performance, therefore, long-time use can hardening, aging, variable color etc., thereby, prolong its work-ing life widely:
(4), TPE is a kind of Halogen plastic material, is a kind of environment-friendly materials that are acknowledged as in the world;
(5), TPE is because its mechanicalness is fairly good, and elongation at break is greater than 500%, tensile strength is greater than 8/Mpa, surpass 350,000 times at the switch door test life of refrigerator, than the common PVC gasket switch test life-span above 3 times:
(6), TPE is owing to have the characteristic of rubber, so its elasticity is very good, compression set is fewer, and the distortion back recovers therefore, to have improved the sealing property of door of refrigerator strip of paper used for sealing greatly also than being easier to, thereby improved the ice making effect of refrigerator, reduced energy consumption;
(7), cold air shed must through annular air-pocket can be again air bag and outside air by the outside carry out heat exchange, have environmental protection, be not subject to the influence of variation of ambient temperature, reduce cold consumption greatly.
(8), greatly increase the sealing effectiveness of door envelope and refrigerator body, reduce heat extraction coefficient, thereby reach energy-conservation purpose, and have and cut down the consumption of energy and advantage such as long service life.
Embodiment
For technique means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
A kind of refrigerator, refrigerator magnetic door strip of paper used for sealing, described gasket are TPE elastomerics door sealing cover, and the cross section of described gum cover is an annular air-pocket, wears magnetic stripe on gasket, and described TPE elastomerics door sealing cover mainly is made of the raw material of following weight part ratio:
SEBS 46-48 part
