Abstract
The invention relates to a method for dispersing hot-melt adhesive filler. The method comprises the following steps that: filler and other components of hot-melt adhesive are evenly mixed by granulation equipment; or part of the filler and other components of the hot-melt adhesive are evenly mixed and granulated by granulation equipment, and then the left over filler is evenly mixed with the granulated mixture. Other components of the hot-melt adhesive comprise main body resin, tackifying resin and a diluent agent; the filler comprises toner, flash powder, calcium carbonate, micro silicon powder, talc powder, white carbon black, light white carbon black, metal nitride, metal oxide and metal nitride or metal oxide; moreover, extruding granulation adopts a single screw extruder or a double screw extruder. The method has the advantages that: the addition of a poisonous and harmful dispersing agent is reduced to protect the environment; the filler is evenly mixed through a physical method, and manufacturing technique is simplified to reduce cost; and because a granular material contains less air volatile matter, the product is not easy to generate air bubbles, thereby ensuring product quality.
Description
Technical field
The present invention relates to a kind of chemical industry tackiness agent filler, particularly a kind of dispersing method of hot-melt adhesive fillers.
Background technology
Ethylene-vinyl acetate copolymer (EVA) based hot melt adhesive can be widely used in civil areas such as bookbinding, automatic packaging production line, carpet backing.Along with the raising of production automation degree, the demand of this product is also increasing.
This product is made up of raw materials such as matrix resin, tackifying resin, thinners, and its cost is higher relatively.One of means that reduce cost are to add some fillers in component, filler commonly used is: lime carbonate, silicon powder, talcum powder, white carbon black, the white carbon black of lightweight, metal nitride, metal oxide etc., but the shortcoming of these fillers is or than great, easily sink to the bottom, disperse bad, or too expensive.As United States Patent6,750,55 have provided a kind of semi-conductive tackiness agent that is used for, and wherein contain metal nitride, metal oxide.
Agglomeration technique has obtained application more and more widely in all trades and professions such as medicine, food, building materials, chemical industry, metallurgy, and agglomeration technique itself is also constantly innovated, developed and improve in the process of using simultaneously, and has createed multiple different prilling process.As boiling type fluidized bed granulation, spraying drying formula comminution granulation, centrifugal fluidized bed granulation, extrude spheronization, extrusion molding etc.These methods respectively have characteristics and different purposes.Be the simplest prilling process of fundamental sum wherein, be widely used in various plastic shapings processing with the extrusion molding granulation.
With particulate material processing and powder directly processing compare, as follows with the advantage of the particulate material of granulation: (1) is reinforced convenient, need compulsory feeder be installed at loading hopper.(2) the particulate material relative density is bigger than powder material, and product strength is better.(3) resin is more even with mixing of various pressed powder material or liquid adjuvants, and physical properties of articles is more even.(4) combinations color and lustre is even.(5) it is less that the particulate material kind contains air agent volatile matter, makes goods be difficult for producing bubble.(6) particulate material is pollution-free to forcing machine and production environment.The extruding pelletization method applies to hot-melt adhesive fillers dispersion aspect and does not also appear in the newspapers.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of dispersing method of hot-melt adhesive fillers, solves the uniformly dispersed problem of hot-melt adhesive fillers, and do not add poisonous and hazardous dispersion agent in dispersion process.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of dispersing method of hot-melt adhesive fillers utilizes granulating equipment other composition uniform mixing with filler and hot melt adhesive, perhaps utilize granulating equipment other composition uniform mixing granulation with a part of filler and hot melt adhesive after, with remaining filler uniform mixing again;
Other composition of wherein said hot melt adhesive comprises matrix resin, tackifying resin and thinner;
Described filler comprises: toner, flashlight powder, lime carbonate, silicon powder, talcum powder, white carbon black, the white carbon black of lightweight, metal nitride, metal oxide, metal nitride or metal oxide;
Described matrix resin is selected from one or more compositions among ethene and vinyl acetate copolymer eva and ethene and butyl acrylate copolymer EMA, ethylene and acrylic acid copolymer EAA, ethene and ethyl propylene acid copolymer EEA, vinylbenzene and isoprene copolymer SIS, copolymer from styrene and butadiene SBS, the amorphous alpha-olefinic polymer APAO, also can use ethylene and vinyl acetate copolymer EVA separately, but its cost is higher;
Described tackifying resin comprises one or more compositions in rosin, polymerized rosin, 145 resins, 138 resins, terpine resin, petroleum resin or the hydrogenated petroleum resin;
Described thinner comprises paraffin, ceresine, polyethylene wax or Fischer-Tropsch wax;
Described flashlight powder comprises can be luminous or the flash of light material;
Described pigment comprises mineral dye or pigment dyestuff;
Extruding pelletization adopts single screw rod or twin screw extruder, and the disposable granulation of other composition of all fillers and hot melt adhesive perhaps after other composition elder generation granulation with filler partly and hot melt adhesive, mixes granulation again with remaining uniform filling again;
Do not add poisonous and hazardous dispersion agent.
The invention has the beneficial effects as follows:
1, reduce the adding of poisonous and hazardous dispersion agent, the protection environment improves added value of product;
2, by physical method filler is mixed, simplify production technique, reduce cost;
3, since the particulate material kind to contain the air volatile matter less, make goods be difficult for producing bubble, guarantee quality product.
