Abstract
The invention discloses a hot melt adhesive used in a refrigerator evaporator. The hot melt adhesive is prepared from the following raw materials in parts by weight: 90-100 parts of Formosa plastic 210MEVA, 25-30 parts of polyolefin elastomer, 10-25 parts of antioxidant, 5-8 parts of titanium dioxide, 8-10 parts of thermoplastic styrene-butadiene rubber, 0.2-0.4 part of aluminum oxide, 0.1-0.2 part of nano zinc oxide and 5-8 parts of composite filler. The hot melt adhesive disclosed by the invention overcomes the defects of the prior art and is reasonable in formula design and strong in cold resistance, the bonding strength of the hot melt adhesive does not significantly decline in a cold environment, and meanwhile, the hot melt adhesive is long in service life and simple in preparation.
Description
Technical field
The present invention relates to refrigeration technology field, specifically belong to a kind of hot melt adhesive for evaporator of refrigerator.
Background technology
Plate-type evaporator is the main heat-exchanger rig in refrigeration system, its effect is to make the liquid refrigerant of low-temp low-pressure evaporate rapidly (boiling) therein for steam, the heat of the material that absorption is cooled, makes refrigeration (freezing) thereby the decline of the temperature of material reaches the object of refrigeration.Vaporizer is mainly made up of metal tube and metal sheet combined process, and aluminum pipe and aluminium sheet are directly bondd.Existing this mode bonding method, pastes by hot melt adhesive, to such hot melt adhesive, there are thermal conductivity and firm pasting to have higher requirement, the cohesive force of prior art hot melt adhesive is unstable, is subject in Working environment the impact that temperature and humidity change sooner or later, and this just can not ensure firmness.
Summary of the invention
The object of this invention is to provide a kind of hot melt adhesive for evaporator of refrigerator, overcome the deficiencies in the prior art, formulating of recipe is reasonable, and bright cold tolerance is strong, and under severe cold environment, cohesive strength can significantly not decline, and life-span while is long, and preparation method is simple.
The technical solution used in the present invention is as follows:
A kind of hot melt adhesive for evaporator of refrigerator, described hot melt adhesive is made by the raw material of following weight parts: platform is moulded 240MEVA90-100 part, polyolefin elastomer 25-30 part, oxidation inhibitor 10-25 part, titanium dioxide 5-8 part, thermoplastic styrene butadiene rubber 8-10 part, aluminium sesquioxide 0.2-0.4 part, nano zine oxide 0.1-0.2 part, compounded mix 5-8 part;
Described compounded mix is made up of the raw material of following weight part:
Hollow ceramic microspheres 5-6 part, ground barium sulfate 22-26 part, oyster shell whiting 8-10 part, kaolin 8-10 part, Radix Angelicae Sinensis oil 1-2 part, dinoctyl phthalate 0.2-0.4 part,, Silane coupling agent KH550 1-2 part, clorafin 1-2 part, wood fibre 0.3-0.5 part, epoxy oleum lini 1-2 part.
The preparation method of described compounded mix is: ground barium sulfate, oyster shell whiting are mixed, at 800-900 DEG C, calcine 2-3 hour, then, take out, add in suitable quantity of water and mix in the lump with hollow ceramic microspheres and kaolin, three-roll grinder grinds 2 hours, and adding 10-15% sodium hydroxide solution tune PH is 8-9, and ground slurry is to 800-900 order, add again hydrochloric acid soln and be adjusted to neutrality, dry, then mix with surplus stock, ground and mixed evenly and get final product.
Compared with the prior art, beneficial effect of the present invention is as follows:
The present invention 4 hot melt adhesive that melten gel curing speed is fast, cohesive force is stable; Not moisture and other any solvents of hot melt adhesive, be easy to transport, storage, long service life, and eliminated and damaged and waste, easy to use; Hot melt adhesive can not send register toxic smog containing solvent yet, and nonflammable, blast, has security, and can not cause to environment the health of secondary pollution and harmful to human.
