Abstract
The invention discloses a modified epoxy resin adhesive. The modified epoxy resin adhesive is composed of the following components by weight: 60-80 parts of epoxy resin E-44, 30-50 parts of epoxy resin D-17, 10-30 parts of polysulfide rubber, 6-10 parts of 2-ethyl-4-methylimidazole, 3-5 parts of diallyl phthalate, 2-4 parts of diethylenetriamine, 20-40 parts of silica powder and 10-20 parts of kaolin. Compared with a conventional epoxy resin adhesive, the modified epoxy resin adhesive provided by the invention has the following beneficial effects that (1) the modified epoxy resin adhesive has good adhesion power, high mechanical strength, excellent corrosion resistance, heat resistance, acid and alkali resistance, and good insulativity; (2) the modified epoxy resin adhesive has a wide application scope and has good adhesive capacity within a temperature range of -60-100 DEG C; and (3) a cured adhesive layer can be processed mechanically and the modified epoxy resin adhesive is suitable for bonding aluminum and aluminum alloy, steel and glass fiber reinforced plastics.
Description
Technical field
The invention belongs to adhesive technology field, more specifically relate to a kind of modified epoxide resin adhesive and preparation method thereof.
Background technology
Epoxy resin is to be prepared by epoxy chloropropionate and bisphenol-a reaction, is thermoplastic resin when uncured, just crosslinking reaction occurs and becomes netted or three dimensional structure when adding after solidifying agent.Every is that the tackiness agent that base-material is made into is referred to as epoxyn with epoxy resin.
Although the hardness of epoxy resin own is high, rigidity is strong, toughness is poor, and anti-inhomogeneous pull strength and shock resistance are poor.In addition, contain the hydrophilic radicals such as great amount of hydroxy group due to epoxy resin, therefore water-fastness poor
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists, a kind of modified epoxide resin adhesive is provided.
Another object of the present invention is to provide the preparation method of this modified epoxide resin adhesive.
For achieving the above object, the present invention has taked following technical scheme:
A kind of modified epoxide resin adhesive, in weight part, composed of the following components:
Epoxy resin E-44: 60～80, epoxy resin D-17:30～50,
Thiorubber: 10～30,2-ethyl-4-methylimidazole: 6～10,
Diallyl phthalate: 3～5, diethylenetriamine: 2～4,
Silicon dioxide powder: 20～40, kaolin: 10～20.
The preparation method of described modified epoxide resin adhesive, comprises following technological step:
(1) epoxy resin E-44, epoxy resin D-17 and thiorubber are mixed, A component is uniformly dispersed to obtain;
(2) 2-ethyl-4-methylimidazole, diallyl phthalate and diethylenetriamine are mixed, B component is uniformly dispersed to obtain;
(3) silicon dioxide powder and kaolin are mixed, C component is uniformly dispersed to obtain;
(4) A, B and C component are mixed, after being fully uniformly mixed, get final product to obtain finished product.
Compared with prior art, the present invention has following beneficial effect:
(1) bounding force of the present invention is good, and physical strength is high, has good rotproofness, thermotolerance, resistance to acids and bases, and has good insulating property.
(2) use range is wide, within the scope of-60-100 ℃, has good stickiness;
(3) solidify after glue-line can carry out mechanical workout, be suitable for the bonding of aluminium and aluminium alloy, steel and glass reinforced plastic.
Embodiment
Below in conjunction with specific embodiment, the invention will be further described.
