Description
Technical field
The invention belongs to refrigeration equipment manufacturing technology fields, in particular it relates to a kind of refrigeration equipment environmental protection and energy saving
Structure sheaf.
Background technique
Refrigeration equipment generally uses hard polyurethane foams as thermal insulation layer, and hard polyurethane foams generally use at present
Pentamethylene (CP), hydrofluoroalkane (HCFC, HFC) and HF hydrocarbon (HFO) are used as foaming agent.Due to forth generation foaming agent hydrogen fluorine alkene
Hydrocarbon HFO has the latent value (GWP) of lower greenhouse effects and a zero latent value (ODP) of consumption ozone, at the same using HFO foaming agent every
Thermosphere can improve refrigerating device heat insulation performance, refrigeration equipment energy consumption grade be effectively reduced, therefore energy-saving and environment-friendly HFO will gradually can
The foaming agents such as the hydrogen fluorochlorohydrocarbon before substitution (CP, HCFC, HFC).
But HFO as foaming agent when, HFO has severe corrosive, especially HFO pairs to plastic part in refrigeration equipment
Common acrylonitrile-butadiene-styrene (ABS) (ABS) end cap generates serious environmental stress, wherein HFO corrosivity ratio CP, HCFC
It is even more serious with HFC.Generally believe that HFO foaming agent is difficult to apply the refrigeration equipment in ABS end lid in industry at present, reason exists
In HFO foaming agent belongs to fluorochemical, is easy to corrode resin, and boiling point is lower, gasification is easy under room temperature, activity performance is more
Greatly.When HFO foaming agent enters in ABS resin, since HFO foaming agent has stronger solvation, macromolecule foams in HFO
It can be plasticized under the influence of agent.Wherein butadiene rubber is easier to absorb foaming agent, butadiene rubber and acrylonitrile-benzene in ABS
Ethylene interfacial interaction dies down, in stress concentration region especially refrigeration equipment ABS product corner part and low temperature contact zone
Domain is easier to wreck, and often appears as multiple crazing and cracking.In addition, ABS end lid have preferable processability and compared with
High glossiness, this makes the structure of refrigeration equipment design more diversified and taste more high-endization.Therefore, it is necessary to find solution
Certainly ABS door body end cap and the compatible application method of HFO foam insulation.
Patent CN 103319834 is disclosed using HIPS, PE and SBS blending and modifying HIPS material as refrigeration equipment mouth frame,
Although having preferable chemical corrosion resistance, modification HIPS material preparation process is complex, and its gloss is poor, it is difficult to
Meet high-end taste required by refrigeration equipment product appearance.
Summary of the invention
The present invention is directed to overcome the defect of the above-mentioned prior art, a kind of end cap made of modified ABS resin, institute are provided
It states end cap and overcomes ABS end lid and be difficult to compatible problem with HFO foam insulation, the effective foaming agent of resistance to HFO corrosion, in high/low temperature
It under circulation change, will not crack, while remain ABS end lid good moldability and the higher advantage of glossiness.
Another object of the present invention is to provide a kind of refrigeration of end cap made of ABS resin comprising the modification to set
Standby environmental protection and energy saving structure sheaf.
Another object of the present invention is to provide the refrigeration equipment environmental protection and energy saving structure sheafs to prepare refrigerator, refrigerator-freezer and wine
Application in cabinet.
Foregoing invention purpose of the invention is achieved by following scheme.
The vinyl cyanide of ethylene propylene diene rubber toughening-aromatic vinyl polymer is preparing answering in refrigeration equipment end cap
With vinyl cyanide-aromatic vinyl polymer of the ethylene propylene diene rubber toughening is blended with ABS is prepared into modified aromatic race second
Ene based resins, then it is prepared into refrigeration equipment end cap；In modified aromatic race vinylite, increase relative to ethylene propylene diene rubber
Tough vinyl cyanide-aromatic vinyl polymer and ABS total amount, vinyl cyanide-aromatic series second of ethylene propylene diene rubber toughening
The weight content of alkene polymer is 20~95%.
Inventors have found that vinyl cyanide-aromatic vinyl polymer using ethylene propylene diene rubber toughening substitutes part ABS
Resin can greatly promote high-low temperature resistant, the anti-aging and resistance to chemical corrosion of material.When modified aromatic race vinyl
In resin, when vinyl cyanide-aromatic vinyl polymer weight content of ethylene propylene diene rubber toughening is 20~95%, end cap
Cracking phenomena will not be generated.
Preferably, the vinyl cyanide of the ethylene propylene diene rubber toughening-aromatic vinyl polymer weight content is 30
~95%.Inventors have found that when vinyl cyanide-aromatic vinyl polymer dosage of ethylene propylene diene rubber toughening is in this range
When interior, it can further make end cap flat and smooth.
When the vinyl cyanide of ethylene propylene diene rubber toughening-aromatic vinyl polymer too high levels, modified aromatic can be given
The processability of race's vinylite is brought a negative impact, and makes it difficult to be molded into end cap by processing.Consider molding processibility
Can, vinyl cyanide-aromatic vinyl polymer content of ethylene propylene diene rubber toughening of the present invention can be more preferably 30~
60%.When the vinyl cyanide of ethylene propylene diene rubber toughening-aromatic vinyl polymer too high levels, cost can also be significantly risen.
The advantage of comprehensive performance and cost, vinyl cyanide-aromatic vinyl polymer dosage of ethylene propylene diene rubber toughening of the present invention
Further preferably 30 ~ 40%.
Preferably, in modified aromatic race vinylite, the weight content of ABS is at least 5%.
In modified aromatic race vinylite, can also contain suitable auxiliary agent, the auxiliary agent can be lubricant,
The auxiliary agent commonly used in the art such as antioxidant.
In the vinyl cyanide of the ethylene propylene diene rubber toughening-aromatic vinyl polymer, the ethylene propylene diene rubber is
The EPDM rubber of grafting, graft are acrylonitrile-styrene, and the vinyl cyanide is acrylonitrile or methacrylonitrile, the virtue
Fragrant race's ethylene is styrene, α-methylstyrene or vinyltoluene.
A kind of refrigeration equipment environmental protection and energy saving structure sheaf, including by HFO blown rigid polyurethane froth bed and by the modification
End cap made of aromatic vinyl resin.
The HFO blown rigid polyurethane froth bed can continue to use the HFO blown rigid polyurethane froth bed of known technology.
Normally, this HFO blown rigid polyurethane froth bed is reacted by polyalcohol, the foaming agent containing HFO, catalyst and isocyanates
It is made.
Preferably, the foaming agent containing HFO is for the single foaming agent of HFO class foaming agent composition or by HFO class foaming agent
The mixed foaming agent formed with other non-HFO class foaming agents.
Alternatively, the HFO class foaming agent is trans- 1- chloro-3,3,3 ,-trifluoropropene (HFO-
1233zd), at least one of hexafluorobutene (HFO-1336mmz).
Alternatively, the mixed foaming agent is HFO class foaming agent and alkane and/or HFC class foaming agent group
At mixture.
It is highly preferred that the alkane is pentane, the pentane is at least one selected from pentamethylene, isopentane and pentane
Kind.
It is highly preferred that the HFC class foaming agent is at least one of HFC-245, HFC-365mfc, HFC-134a.
The refrigeration equipment environmental protection and energy saving structure sheaf is preparing the application in refrigerator, refrigerator-freezer and wine cabinet.
Compared with prior art, the invention has the following beneficial effects:
The present invention using modified aromatic race vinylite substitute ABS resin, both remained itself glossiness of ABS end lid compared with
The advantages of height, good moldability, and significantly improve the chemical corrosion resistance of end cap, solve now that refrigeration equipment ABS end lid is not
The problem of HFO foaming agent can be used；Refrigeration equipment environmental protection and energy saving performance is improved using modified aromatic race vinylite；This hair
The moulding process of bright end cap is consistent with current common ABS end lid, remains good mouldability, the structure of refrigeration equipment can be made to set
Meter is more diversified and samples more high-endization.
