Abstract
The invention discloses an environment-friendly hot-melt adhesive for paper-plastic compounding, which is composed of the following components in parts by weight: 50-60 parts of wheat modified starch, 20-30 parts of PLA (polylactic acid) resin, 15-20 parts of terpene resin, 5-10 parts of microcrystalline wax, 2-6 parts of dibutyl phthalate, 0.5-1 part of 2,6-di-tert-butyl-para-cresol and 1-5 parts of talcum powder. By using the modified wheat starch as the main base material, the cost of the product is greatly lowered. The hot-melt adhesive has favorable bonding performance, and can be widely used for paper-plastic compounding packaging.
Description
Technical field
The present invention relates to hot melt adhesive technical field, be specifically related to a kind of paper-plastic stick environment-friendly type hot melt glue.
Background technology
In the production of hot melt adhesive, the past generally only considers its adhesiveproperties, and does not consider its degradation property.In recent years, along with the increasing substantially of consumption of hot melt adhesive, its problem caused also shows especially day by day.Produce the matrix resin of hot melt adhesive the most frequently used have the macromolecule organic such as ethene and multipolymer, polyolefine, vinylbenzene and segmented copolymer thereof; due to its structural performance; make it to be not the microbiological deterioration in environment or hydrolysis, therefore can bring many unfavorable factors to the protection of environment and closed matereial cycle.Along with the enhancing of the increasingly sound of environmental regulation and people's environmental consciousness, the good and degradable environment-friendly hot melt adhesive of production bonding strength oneself become the important development direction of adhesive industry.
Summary of the invention
The object of the present invention is to provide a kind of paper-plastic stick environment-friendly type hot melt glue, the good and degradable of paper bonding strength.
For achieving the above object, this invention takes following technical scheme:
A kind of paper-plastic stick environment-friendly type hot melt glue, with parts by weight, composed of the following components:
Wheat treated starch: 50 ~ 60, PLA resin: 20 ~ 30, terpine resin: 15 ~ 20,
Microcrystalline wax: 5 ~ 10, dibutyl phthalate: 2 ~ 6,
2,6 ditertiary butyl p cresol: 0.5 ~ 1, talcum powder: 1 ~ 5.
The preparation technology of described paper-plastic stick environment-friendly type hot melt glue is: the wheat starch after modification and biodegradable polyesters PLA, tackifier, viscosity-controlling agent, softening agent, antioxidant, filler are mixed in proportion, join in Twin screw extruder and carry out blending extrusion, charging opening is 100 ~ 150 DEG C to head temperature, screw speed 60 ~ 80rpm, residence time of material is 4 ~ 6 minutes.
The invention has the beneficial effects as follows: the present invention for major matrix material, significantly reduces the cost of product with the wheat starch of modification; Adhesiveproperties is good, can be widely used in paper plastic combined package.
