Abstract
The embodiment of the invention discloses a hot-melt adhesive which comprises the following components in percentage by mass: 25-45% of an ethylene-vinyl acetate copolymer, 15-20% of rosin modified phenolic resin, 10-25% of paraffin, 0.05-0.4% of 2,6-butylated hydroxytoluene and 3-12% of light calcium carbonate. The hot-melt adhesive has the advantages of convenience in construction, rapid curing speed, high production efficiency and the like.
Description
Technical field
The present invention relates to chemical field, particularly relate to a kind of manufacture of hot melt adhesive.
Background technology
Hot melt adhesive is also known as hot melt adhesive, and be a kind of plastic tackiness agent, in certain temperature range, its physical condition changes with temperature change, and chemical property is constant, and it is nonpoisonous and tasteless, belongs to environmental-protecting chemical product.。By obtaining mobility after heat fused during use, infiltrate adherend surface, and realize bonding by firmly solid or reaction solidification after cooling, the composition of hot melt adhesive mostly is matrix resin+tackifier+softening agent+oxidation inhibitor+filler.
Hot melt adhesive, compared with other tackiness agent, has following characteristic:
(1) adhering speed is fast, after heat fused, contact adherend surface time the several seconds in just can solidify, be applicable to automatization and continuous production technology.
(2) not containing solvent, to human non-toxic, free from environmental pollution, transport and keeping convenient.
(3) can multiple material be bonded, can be used for bonding timber, paper, metal, glass, plastics, pottery, dress material, electronic component, wrapping material etc., even other tackiness agent are difficult to the materials such as bonding paraffin paper and also can bond.
(4) chemical proofing is strong, can water-fast, salt solution, oil, acid, the erosion such as alkali and gasoline.
(5) can use be reheated, be coated in the hot melt adhesive on adherend body, because of cooling curing can not bond time, or when bond site need change, can reheat and carry out bonding operation.
But it is not high that hot melt adhesive exists this thermostability, and thermotolerance is poor, can only could use by heating and melting, operation is by shortcomings such as amblent air temperature affect.
Summary of the invention
Embodiment of the present invention technical problem to be solved is, provides a kind of hot melt adhesive, comprises following component in mass ratio:
Vinyl-vinyl acetate copolymer 25% ~ 45%
Rosin modified phenolic resin 15% ~ 20%
Paraffin 10% ~ 25%
2,6-ditertbutylparacresol 0.05% ~ 0.4%
Light calcium carbonate 3% ~ 12%.
In order to solve the problems of the technologies described above, embodiments provide a kind of technique preparing described hot melt adhesive, comprising the following steps:
A () first adds paraffin in the reactor of belt stirrer;
(b) add when temperature being risen to 100 DEG C vinyl-vinyl acetate copolymer, rosin modified phenolic resin and 2,6-ditertbutylparacresol;
C () continues to be warming up to 170 DEG C, be incubated 1.5 hours;
D () adds light calcium carbonate, continue insulation discharging in 1 hour.
Implement the present invention, there is following beneficial effect:
The present invention has that easy construction, solid speed are fast, production efficiency advantages of higher.
Embodiment
For making the object, technical solutions and advantages of the present invention clearly, below the present invention is described in further detail.
Embodiment
Vinyl-vinyl acetate copolymer 45g
Rosin modified phenolic resin 25g
Paraffin 20g
2,6-ditertbutylparacresol 0.4g
Light calcium carbonate 9.6g.
In order to solve the problems of the technologies described above, embodiments provide a kind of technique preparing described hot melt adhesive, comprising the following steps:
A () first adds paraffin in the reactor of belt stirrer;
(b) add when temperature being risen to 100 DEG C vinyl-vinyl acetate copolymer, rosin modified phenolic resin and 2,6-ditertbutylparacresol;
C () continues to be warming up to 170 DEG C, be incubated 1.5 hours;
D () adds light calcium carbonate, continue insulation discharging in 1 hour.
During use, hot melt adhesive is placed in hopper and is heated to 140 ~ 160 DEG C, become molten, with roller coat or blade coating.
Above disclosedly be only a kind of preferred embodiment of the present invention, certainly can not limit the interest field of the present invention with this, therefore according to the equivalent variations that the claims in the present invention are done, still belong to the scope that the present invention is contained.
