Abstract
The invention discloses a hot melt adhesive with polybutylene terephthalate as a main material and its preparation method. The hot melt adhesive comprises the following raw materials by weight part: 60-70 of polybutylene terephthalate, 20-30 of polyphenylene ether, 5-7 of polytetrafluoroethylene, 28-32 of an acrylic emulsion, 12-15 of PE wax, 20-30 of light calcium carbonate, 1.2-1.5 of mixed powder, 1-3 of methyltriethoxysilane, 2.5-3.5 of isophthalic acid ester, and 1.0-2.0 of benzotriazole. The hot melt adhesive provided in the invention has a reasonable formula and a simple preparation method. The adding of PE wax in the raw materials raises the softening point temperature of the prepared hot melt adhesive. Meanwhile, the adding of the light calcium carbonate and the acrylic emulsion increases the bonding strength of the hot melt adhesive, which can have good fluidity. The hot melt adhesive disclosed in the invention has the advantages of environmental protection, safety, weatherability and low cost.
Description
Technical field
The present invention relates to field of high polymer material processing, being specifically related to a kind of take polybutylene terephthalate as hot melt adhesive of major ingredient and preparation method thereof.
Background technology
Hot melt adhesive take thermoplastic resin as the not solvent-laden solid adhesive agent of main component, due to hot melt adhesive, to have binding speed fast, nontoxic, adhesion technique has simply again the advantages such as good bond strength and snappiness, it can to various material as timber, paper, fiber, metal, plastic stool carries out bonding, use range is wide, special in fiber industry, packing business and bookbinding industry more have a large amount of use, but most of hot melt adhesive adopts polyester, prepared by the hot-melt resins such as polymeric amide, due to the intensity of polyester hot-melt adhesive and elasticity poor, too large external force can not be born, again due to the fusing point of polyamide hot and hardness higher, therefore be restricted in use.
Summary of the invention
The object of the present invention is to provide a kind of take polybutylene terephthalate as hot melt adhesive of major ingredient and preparation method thereof.
The present invention adopts following technical scheme:
Take polybutylene terephthalate as the hot melt adhesive of major ingredient, the weight part of its constitutive material is: polybutylene terephthalate 60-70, polyphenylene oxide 20-30, tetrafluoroethylene 5-7, ACRYLIC EMULSION 28-32, PE wax 12-15, light calcium carbonate 20-30, powder mix 1.2-1.5, Union carbide A-162 1-3, isophthalic acid ester 2.5-3.5, benzotriazole 1.0-2.0.Described powder mix mixes by waiting the cotton fibre powder of weight part, polypropylene fiber powder, iron powder, wood fiber powder, pulp powder.
Take polybutylene terephthalate as the hot melt adhesive of major ingredient, the weight part of its constitutive material is: polybutylene terephthalate 65, polyphenylene oxide 25, tetrafluoroethylene 6, ACRYLIC EMULSION 30, PE wax 14, light calcium carbonate 25, powder mix 1.4, Union carbide A-162 2, isophthalic acid ester 3, benzotriazole 1.5.
Take polybutylene terephthalate as the preparation method of the hot melt adhesive of major ingredient, comprise the following steps:
(1) raw material is mixed, obtain the material mixed;
(2) material is put into extruding pelletization in cocurrent and parallel modular twin-screw extruders, setting barrel heat temperature is 200-220 DEG C, die temperature is 170-180 DEG C, screw speed is 40-60rpm, reinforced rotating speed is 30-40rpm, until material after die extrusion through tank cooling after blank, obtain hot melt adhesive.
Beneficial effect of the present invention:
The present invention fills a prescription rationally, preparation method is simple, with the addition of PE wax in the feed, the softening point temperature of the hot melt adhesive obtained is improved, with the addition of light calcium carbonate and ACRYLIC EMULSION simultaneously, add the cohesive strength of hot melt adhesive, good fluidity, the present invention has environmental protection, safety, weathering resistance and advantage with low cost.The present invention adopts compound, enhances the viscosifying power of hot melt adhesive and inhomogeneity carrier.
Embodiment
Embodiment 1: the hot melt adhesive taking polybutylene terephthalate as major ingredient, the weight part (kg) of its constitutive material is: polybutylene terephthalate 65, polyphenylene oxide 25, tetrafluoroethylene 6, ACRYLIC EMULSION 30, PE wax 14, light calcium carbonate 25, powder mix 1.4, Union carbide A-162 2, isophthalic acid ester 3, benzotriazole 1.5.Described powder mix mixes by waiting the cotton fibre powder of weight part, polypropylene fiber powder, iron powder, wood fiber powder, pulp powder.
Take polybutylene terephthalate as the preparation method of the hot melt adhesive of major ingredient, comprise the following steps:
