Description
Technical field
The present invention relates to a kind of preparation method of hot melt adhesive, more particularly to a kind of preparation of health type low-temperature hot melt adhesive
Method.
Background technology
Low-temperature heat melting film elasticity is high, and rigidity is splendid, deflects extremely strong, stereoscopic effect more pole after the front and rear real sizing of bag
It is excellent, it is non-toxic and tasteless, pollution will not be generated, sizing easy to operate is unlikely to deform after making product shoes, and the lines flow smoothly for display, dress
Comfortable elastic is splendid, and shape keeps lasting, and without brush coating water, caking property is good, and operation is extremely convenient, and can reuse, product
Environmentally protective leftover pieces can be a kind of ep-type material with recycling, substitute traditional current footwear materials of material in the market
Low-temperature heat melting film can be used for all kinds of shoes shaping middle soles and automotive trim, luggage, handbag, stationery, toy, leatherware, furniture
The fields of grade.
The low-temperature hot melt adhesive of the prior art has the disadvantage that：Gas permeability is general, makes that people cannot be excluded inside shoes completely
Absorbing sweat hydrofuge drying effect is not achieved in body foot sweat, so as under long-term wet environment, promote the procreation of bacterium, cause foot
A series of generation of foot's diseases such as tinea pedis, peculiar smell or even rotten, decortication, similarly hygroscopic desiccation performance is bad, can also give automobile
The mould growths such as interior trim, leatherware reduce its service life.
The content of the invention
It is an object of the invention to solve the deficiencies in the prior art, a kind of preparation side of health type low-temperature hot melt adhesive is provided
Method.
The technical solution adopted by the present invention to solve the technical problems is：
The preparation method of health type low-temperature hot melt adhesive,
Raw material includes the component of following parts by weight：TPU heats 45-60 parts of gum resin, 10-20 parts of PETG, anion/bamboo

（1）Above-mentioned each raw material is put into in material storage mechanism respectively and is carried out by high-strength magnetic except metal；
（2）30-45min will be carried out being sufficiently stirred in each feedstock transportation to material cylinder to uniform；
（3）The raw material being stirred is delivered to the feed hopper of curtain coating extruder after secondary strong magnetic removes metal again, is fed through metering
Expect that by default quantitative progress at the uniform velocity feeding to screw machine, uniform flow is kneaded by 130-150 DEG C of high-temperature fusion of screw machine for mechanism
Prolong into sheet material, then shape through cold pressing;
The TPU hot melts gum resin is that curtain coating grade thermoplasticity polyurethane resin flow starting temperatures are 60 DEG C, and melting refers to
Number is 10 ± 5, and hardness is 97 ± 2, curing rate 5min；
The anion/activated carbon from bamboo composite material is by negative ion powder and activated carbon from bamboo powder, in mass ratio 0.8-
1:1 be milled to using appropriate amount of deionized water as medium it is powdered, add appropriate polyvinyl alcohol wet-milling 24-28 it is small when after take out, 100-
110 DEG C of drying, are placed in vacuum sintering furnace, and under nitrogen protection, furnace temperature rises to 700-750 DEG C of calcining high-temperature activation, heat preservation
When 1.5-2 is small, furnace cooling is taken out spare；
The activated carbon from bamboo powder is to grow the mao bamboon of 5 years or more as material, using high temperature carbonization technology, last one
In week, carbonization temperature is controlled at 1000 DEG C, then through high temperature and pressure activation process, makes its charcoal molecule fine and closely woven porous, every gram of bamboo matter activity
The sum of void surface area of powdered carbon >=300m2；
The compatilizer is polyesters compatilizer, and grafting rate is 100 parts.
Preferably, raw material also includes the organobentonite of 1-2 parts by weight.Organobentonite has good thixotropy, change
Stability, dispersiveness are learned, is added in raw material after appropriate organobentonite stirs evenly, you can form stable disperse materials, subsequently
When being used to prepare low-temperature hot melt adhesive, the mass uniformity of low-temperature hot melt adhesive, ventilative homogeneity can be significantly improved.
It is furthermore preferred that parts by weight of raw materials composition is as follows：TPU heats 51 parts of gum resin, 15 parts of PETG, and anion/bamboo matter is lived
28 parts of carbon composite of property, 4 parts of compatilizer, 2 parts of organobentonite.
The beneficial effects of the invention are as follows：
（1）The present invention relates to anion/activated carbon from bamboo material, there is higher practical value, can receive 25 DEG C of human body-
The heat emission of body temperature between 37 DEG C goes out the far infrared wave of the 4um-14um beneficial to human body so that shoe temperature raises 0.4 DEG C
This far infrared waves of left and right can be by human foot bottom acupuncture point, and the moisture in activating human body boosts metabolism, and increases cell
Vigor negative oxygen ions can optimize human peripheral's environment, splendid air purification dedusting, adjust in human body biology section
Rule inhibits aging.
