Description

Functionalization alloy resin
Technical field
The present invention relates to the resist chemicals of refrigerator lining used in refrigerator manufacturing industry and refrigerator door end cap injection molding material Functional resin new material, more particularly to a kind of anti-1- chloro-3,3,3 ,-trifluoropropene (abbreviation LBA), 1,1,1,3,3- five fluorine The refrigerator lining film covered resin and refrigerator of the deep-etching of propane (abbreviation HFC-245fa) and pentamethylene polyploid foaming refrigerant Door body end cap injection molding material.
Background technique
It comes into force from Montreal Protocol in 1998 with after Chinese Government's signature Kyoto Protocol in 1997, people just open Begin to find the course for substituting CFC-11 (F-11) foaming agent.Since man invented Refrigeration Technique, the first generation of refrigerant Product is CFC-11 (F-11), has eliminated one fluorine dichloroethanes (HCFC-141b) of transitional product later, subsequently into the Two generation products, that is, pentamethylene foaming agent epoch.
The third generation freeze foaming agent be HFC-245fa (1,1,1,3,3- pentafluoropropane) and HFC-365mfc (1,1,1,3, 3- 3-pentafluorobutane).
Forth generation refrigeration foaming agent is LBA (the chloro- 3,3,3- trifluoro propene of 1-).
Why both at home and abroad to refrigeration foaming replacement so frequent? because of first generation refrigerant CFC-11 (freon- 11) very big to the depletion of the ozone layer of atmosphere, cause atmosphere ozone layer because the chloride ion in F-11 is under photochemical action Meeting ozone decomposition is converted to oxygen and atmosphere is made to generate black hole, to destroy the environment and greenhouse effects of human survival.It is international Environmental protection organization releases this transitional product of HCFC-141b.Ozone layer and greenhouse effects are destroyed since HCFC-141b is equally existed Defect is only smaller than CFC-11 (F-11) harmfulness.Pentamethylene foaming technique is highly developed at present, but the thermally conductive system of foam Number in the left and right 20mW/ (m.k), continues to reduce extremely difficult always.Therefore, novel third generation foaming refrigerant HFC- has been selected 245fa and HFC-365mfc.
It is sent out as Chinese freon (HCFCs) eliminates the propulsion of plan, HFC-245fa and HFC-365mfc as pentamethylene The substitute products of infusion and HCFC-141b have entered China for many years.Section, Hisense dragon large-scale use HFC-245fa hair in 2009 Infusion.HFC-245fa does not have to be applied to household electric appliances as pure foaming agent as foreign countries, is more and pentamethylene foaming agent It is used in mixed way.Since the GWP value (global warming potential, Global Warming Potential) of HFC-245fa is very high, in Government, state does not encourage to promote.Therefore, HFC-245fa, HFC-365mfc are an awkward transitional product.At the same time, In January, 2015, Europe is forbidden to use HFC-245fa.The U.S. is forbidden to use HFC-245fa within 2016, and Chinese Government also can be gradually Forbid the use of HFC-245fa.
Thus inference, forth generation product LBA (1- chloro-3,3,3 ,-trifluoropropene) will be mainstream refrigerant foamed products, LBA Without combustibility, GWP value is extremely low, and Energy Efficiency Ratio pentamethylene foaming agent improves 10%-12%, and thermal conductivity ratio HFC-245fa is low 8%.Good intensity, dimensional stability and cementability are possessed using the hard polyurethane foam that LBA foams.
Since LBA is at high price, the Haier of China's Mainland, the refrigerator that section, Hisense is imperial, beautiful are all made of the use of LBA 5-9% Amount, the compound prescription of pentamethylene 12-14%.China's Mainland is popular to be known as polyploid foaming technique.But since LBA pentamethylene is compound There is stronger chemical corrosivity and stress cracking resistance, therefore mainly (high with HIPS to refrigerator manufacturing industry liner material after formula Impact-resistant polystyrene) and ABS (acrylonitrile-butadiene-styrene (ABS)) be liner extrusion board.But it also can be because after plastics sucking moulding LBA, pentamethylene corrode and generate cracking, and refrigerator product is caused to scrap, and China Patent No. ZL200710191400.5 is using PE/ PS alloy, but due to the limitation of material, the material application of HIPS refrigerator lining is only adapted to, and cannot be general with ABS, simultaneously because PE/PS alloy material is because PE material adapted is more, so that material has the characteristic of PE and influences refrigerator lining material and polyurethane Foam cementability.Although using sided corona treatment HIPS plate surface, plastic uptake during squeezing out overlay film PE/PS alloy resin The poor compatibility of refrigerator lining material and polyurethane foam material after molding and generate from bubble phenomenon, and influence refrigerator product quality Reliability.Therefore, the present invention is in view of LBA, HFC-245fa, pentamethylene polyploid foaming agent are to refrigerator lining macromolecule material The corrosivity of material causes refrigerator lining material corrosion and stress cracking.
Currently, refrigerator manufacturing industry refrigerator lining material is mainly that (one butadiene one of benzene alkene eyeball is styrene copolymerized by ABS both at home and abroad Object) and HIPS (high impact polystyrene)；This two kinds of material, which does not have, bears LBA, pentafluoropropane, the polynary foaming agent of pentamethylene Corrosion, therefore refrigerator manufacturing industry selects forth generation foaming refrigerant LBA to will cause refrigerator lining material corrosion and stress cracking.
Summary of the invention
The technical problem to be solved in the present invention is that: a kind of functionalization alloy resin is designed, this alloy resin can be kept away Exempt from chloro- 3,3,3- trifluoro propene (LBA) the polyploid foaming agent pair of pentamethylene, 1,1,1,3,3- pentafluoropropane (HFC-245fa), 1- The corrosion of refrigerator lining material of main part (ABS, HIPS) and stress cracking, guarantee refrigerator integral product quality, while with (ABS, HIPS) refrigerator proprietary material has good compatibility.
In order to solve the above-mentioned technical problem, the present invention proposes a kind of following technical scheme: functionalization alloy resin, by following It is grouped as according to the group that mass percent calculates:
The above technical solution is further limited in that the compatilizer is self-control compatilizer, preparation method is as follows It is described: glycidyl methacrylate 1%-5%, the maleic anhydride 0.5-1.5%, diformazan being calculated by mass percentage Base formamide 0.2-0.5%, cumyl peroxide 0.05-0.1%, polyethylene 70-85%, hydrogenated styrene-fourth diblock Copolymer 5-15%, four [β-(3,5- di-tert-butyl-hydroxy phenyl) propionic acid] pentaerythritol ester 0.4%-0.6% pass through double spiral shells Bar extruder melting graft forms, and the sum of each raw material component mass percent of the compatilizer is equal to 100%.
The above technical solution is further limited in that the compatilizer is hydrogenated styrene-butadiene block copolymerization Object, polycthylene grafted cis-butenedioic anhydride, polyethylene to graft glycidyl methacrylate or styrene-acrylonitrile-cis-butenedioic anhydride copolymer.
Compared with prior art, the invention has the following advantages:
Domestic and international Refrigeration Technique is described in background technique because the reason of environmental protection promotes foaming refrigerant to enter forth generation LBA Epoch, China's Mainland major part enterprise use LBA, HFC-245fa, pentamethylene multiplexed combination foaming technique.But due to this more First body foaming agent is very big to refrigerator manufacturing industry inner container of icebox materials A BS, HIPS corrosivity, and product of the present invention all material is state Interior production or the high molecular material that market can be purchased at home.Pass through science, reasonable, effectively preparation.It is squeezed using twin-screw The alloy resin of multifunction low cost made of machine is kneaded out.
