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.
Vinyl cyanide-aromatic vinyl-ethylenic unsaturation acid ester polymer is preparing the application in refrigeration equipment end cap, described
Vinyl cyanide-aromatic vinyl-ethylenic unsaturation acid ester polymer is blended with ABS to be prepared into modified aromatic race vinylite and makes again
For at refrigeration equipment end cap；In modified aromatic race vinylite, relative to vinyl cyanide-aromatic vinyl-unsaturation
The total amount of olefine acid ester polymer and ABS, vinyl cyanide-aromatic vinyl-ethylenic unsaturation acid ester polymer weight content are 20
~95%.
Inventors have found that part ABS resin is substituted using vinyl cyanide-aromatic vinyl-ethylenic unsaturation acid ester polymer,
High-low temperature resistant, the anti-aging and resistance to chemical corrosion of material can greatly be promoted.When modified aromatic race vinylite
In, when vinyl cyanide-aromatic vinyl-ethylenic unsaturation acid ester polymer weight content is 20~95%, end cap will not be generated open
Split phenomenon.
Preferably, the weight content of the vinyl cyanide-aromatic vinyl-ethylenic unsaturation acid ester polymer is 30~95%.
Inventors have found that when vinyl cyanide-aromatic vinyl-ethylenic unsaturation acid ester polymer dosage within this range when, can be into one
Step keeps end cap flat and smooth.
When vinyl cyanide-aromatic vinyl-ethylenic unsaturation acid ester polymer too high levels, modified aromatic race ethylene can be given
The processability of base resin is brought a negative impact, and makes it difficult to be molded into end cap by processing.Consider moulding processability, this hair
The content of bright vinyl cyanide-aromatic vinyl-ethylenic unsaturation acid ester polymer can be more preferably 30~60%.Vinyl cyanide-
When aromatic vinyl-ethylenic unsaturation acid ester polymer too high levels, cost can also be significantly risen.Comprehensive performance and cost it is excellent
The dosage of gesture, vinyl cyanide-aromatic vinyl-ethylenic unsaturation acid ester polymer of the present invention is more 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-aromatic vinyl-ethylenic unsaturation acid ester polymer, the vinyl cyanide is acrylonitrile or first
Base acrylonitrile, the aromatic vinyl are styrene, α-methylstyrene or vinyltoluene, and the ethylenic unsaturation acid esters is third
E pioic acid methyl ester, ethyl acrylate, propyl acrylate, butyl acrylate, isobutyl acrylate, methyl methacrylate, methyl-prop
Olefin(e) acid ethyl ester, propyl methacrylate, butyl methacrylate or Isobutyl methacrylate.
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.
