Abstract
The invention provides a hot melt adhesive, which comprises, based on quality percentage, 50-90 parts of base resin and 10-50 parts of auxiliary agent, wherein the base resin is an ethane-vinyl acetate copolymer, and the auxiliary agent comprises 10-30 parts of adhesion agent, 1-15 parts of viscosity conditioning agent and 1-7 parts of anti-oxidant. The hot melt adhesive provided by the invention is environment-friendly that has a wide temperature scope, convenient usage, strong adhesion stress and stable performance.
Description
Technical field
The present invention relates to jointing material, in particular to a kind of hot melt adhesive.
Background technology
Hot melt adhesive is a kind of plastic tackiness agent, and its physical condition changes along with temperature change in certain temperature range, and chemical property is constant, and is nonpoisonous and tasteless because of it, is a kind of environmental-protecting chemical product, is applied in a lot of industries.But because make the difference of formula, technique, the own characteristics such as the bonding force intensity of hot melt adhesive, adaptive temperature scope, stability are also different, and this will cause the hot melt adhesive quality uneven.
Summary of the invention
The invention solves deficiency of the prior art, provide that a kind of bonding force is strong, the hot melt adhesive of adaptive temperature wide ranges, good stability.
Technical scheme of the present invention is: a kind of hot melt adhesive, by massfraction, its formula is comprised of 50～90 parts of basic resin and 10～50 parts of auxiliary agents, described basic resin is ethylene-vinyl acetate copolymer, and described auxiliary agent is 10～30 parts of tackifier, 1～15 portion of viscosity modifier, 1～7 part of oxidation inhibitor.
Preferably, its formula is comprised of 70 parts of ethylene vinyl acetates, 20 parts of tackifier, 7 portions of viscosity modifiers and 3 parts of oxidation inhibitor.
Preferably, in described ethylene-vinyl acetate copolymer, the massfraction of vinyl acetate is 18～30%.
Preferably, the melting index of described ethylene-vinyl acetate copolymer is 10～600g/10min.
Preferably, described tackifier are a kind of or its mixture in rosin, modified rosin, terpine resin, C5 petroleum resin and C9 petroleum resin.
Preferably, described viscosity modifier is a kind of or its mixture in paraffin, Microcrystalline Wax, polyethylene wax and Poly Propylene Wax.
Preferably, described oxidation inhibitor is hindered phenol type antioxidant.
More preferably, described oxidation inhibitor is four [β-(3,5-di-tert-butyl-hydroxy phenyl) propionic acid] pentaerythritol ester.
The defect that solves prior art of the present invention has following beneficial effect:
1. in the ethylene-vinyl acetate copolymer resin of the present invention's employing, the massfraction of vinyl acetate is 18～30%, and its elasticity is suitable, when melting index is 10～600g/10min, and its good fluidity, the value range of melt temperature is wider.
2. the present invention adds tackifier, has improved the mobility of colloid and the wettability of adherend, improves adhesive property, has good adhesive property.
3. the present invention adopts four [β-(3, the 5-di-tert-butyl-hydroxy phenyl) propionic acid] pentaerythritol ester is as oxidation inhibitor, this oxidation inhibitor is nontoxic, nonflammable, non-explosive, burn into good stability not, meets the hot melt adhesive environmental requirement, and increases stability and the work-ing life of hot melt adhesive.
4. softening temperature of the present invention is 95 ± 5 ℃, easily reaches, and is easy to use, and cohesive force is strong; Second-order transition temperature is-25 ± 5 ℃, and temperature range is wide, and the present invention is a kind of easy to use, and cohesive force is strong, the environment-friendly type hot melt glue that temperature range is wide.
