Abstract
A temp. -resistant adhesive solidifying at ordinary temp is prepared from aliphatic epoxy resin, polyurethane ,baypren, acrylonitrile butadiene (liquid), boronphenolic resin, polyisocyanate, magentsium oxide, zinc oxide, antiagenig agent and alcohol as catalyst, and features high toughness, high-temp performance and adhesion.
Description
Ambient cure heat-resistant adhesive of the present invention belongs to a kind of normal temperature cured type tackiness agent.
Traditional transport tape joint connects normal riveted joint, the hot vulcanization process of adopting and does not only time-consuming consumption but also big and to connect effect bad like this, and product is not durable.Patent documentation CN1063120A has proposed a kind of cold glue normal temperature adhesive sheet, but this sheet is thermo-labile, and intensity is not high yet.
The ambient cure heat-resistant adhesive that the purpose of this invention is to provide a kind of high-toughness high-strength, this glue can be successfully applied to the particularly heat-resisting joint connection of pierce tap of various transport tapes, also can be applied to the stickup of heat insulation and wear resistance ceramics.
To achieve the above object of the invention, the glue system that the present invention proposes is by aliphatic epoxy resin, urethane, chloroprene rubber, paracril (liquid), boron bakelite resin, compositions such as polyisocyanates, magnesium oxide, zinc oxide, anti-aging agent and non-water catalyzer, mixed formulated with suitable composition by weight.Wherein aliphatic epoxy resin, urethane resin shared composition by weight in prescription is respectively 45-90 part and 20-40 part; Chloroprene rubber and paracril (liquid) shared composition by weight in prescription is respectively 30-42 part and 40-50 part; Boron bakelite resin and polyisocyanates shared composition by weight in prescription is respectively 20-35 part and 10-18 part; Magnesium oxide and zinc oxide shared composition by weight in prescription is respectively 15-20 part and 8-10 part; Anti-aging agent and non-water catalyzer ethanol shared composition by weight in prescription are respectively 1-3 part and 2 parts.
What play heat-resisting function in this adhesive formulation is boron bakelite resin and aliphatic epoxy resin; The composition that plays toughening effect is urethane chloroprene rubber and paracril; Magnesium oxide, zinc oxide and polyisocyanates play sulfuration and solidification respectively.
Adopt the boron bakelite resin heat decomposition temperature to reach more than 500 ℃ among the present invention, thermotolerance is fabulous, and contains a large amount of methylols (* 3) group in the molecule, to fine by sticking material sticking power; The aliphatic epoxy resin working viscosity is low, and contains a large amount of epoxy an aromatic plant metioned in ancient books group in the molecule, to good by sticking material sticking power; The polyurethane molecular chain is pliable and tough and good to being glued material sticking power; Chloroprene rubber and paracril have toughening effect, and after system was solidified, they formed rubber disperse phase not of uniform size, play toughness reinforcing enhancement; Magnesium oxide and zinc oxide play sulfuration to rubbery system.
When preparing glue of the present invention, at first with chloroprene rubber, paracril (liquid), magnesium oxide, zinc oxide, boron phenolic aldehyde, anti-aging agent and catalyzer on mixing roll mixing 20 times, add urethane and aliphatic epoxy resin afterwards successively and carry out three rollers and grind 20 times, glue.Before the use, add polyisocyanates.
This glue has good toughness, characteristics such as good heat resistance and bonding strength height, and can ambient cure, easily enforcement.Can be widely used in the particularly heat-resisting joint connection of pierce tap of various transport tapes, can also be applied to the outer thermal insulation ceramics sheet of spacecraft and paste.
