Problems solved by technology

[0003] At present, domestic hot-melt adhesive bonding resins are mainly concentrated on the bonding strength. For example, the patent CN103756599A is a high-temperature-resistant high-adhesive bonding resin. In this respect, the bonding strength performance is not bad; The gap between the resins is still mainly concentrated on the uniform distribution of the grafts. The peel strength of foreign adhesive resins such as Dupont 40E529 adhesive resin and aluminum sheet is very uniform, and the peel force value fluctuates very smoothly; while the domestic adhesive The peeling interface between the resin and the aluminum sheet is not uniform, the glue-hanging interface is not smooth, and the peeling force value fluctuates greatly
One of the main reasons is the process problem, and the other is the formula problem. In China, the grafting is mainly carried out by melt mixing, and in foreign countries, it is mainly carried out through the reactor, but the cost of the reactor is too high, and corresponding environmental protection facilities need to be installed.

Description

technical field [0001] The invention relates to a glass fiber reinforced hot-melt adhesive bonding resin and a preparation method thereof, belonging to the field of bonding resins. Background technique [0002] Adhesive resin is a kind of graft-modified polymer. By grafting comonomers on the main chain of the polymer to form functional branched chains, the functional branched chains exposed outside the main chain can be bonded quickly and efficiently. A chemical reaction occurs with the material. Hot melt adhesive is a kind of plastic adhesive. Its physical state changes with temperature within a certain temperature range, showing a strong bonding effect. The hot-melt adhesive bonding resin described in this patent mainly involves the fields of hot-melt adhesives for composite building materials and high-barrier packaging hot-melt adhesives, such as special hot-melt adhesives for steel mesh reinforced composite pipes, special hot-melt adhesives for steel belt reinforced cor...
