Abstract
A kind of recessed native hot melt adhesive and preparation method thereof, is characterized in that its component is: matrix resin: 20-50%; Tackifying resin: 20-50%; Thinner: 10-30%; Recessed soil: 2-40%; Oxidation inhibitor: 0.1-1%; Wherein said matrix resin is ethene and vinyl acetate copolymer eva, or itself and ethene and butyl acrylate copolymer EMA, ethene one acrylic copolymer EAA, ethylene ethyl acrylic copolymer EEA, vinylbenzene and isoprene copolymer SIS, copolymer from styrene and butadiene SBS, any one or more in amorphous alpha-olefin polymers APAO combine; Described tackifying resin is rosin, polymerized rosin, 145 resins, 138 resins, terpine resin, petroleum resin or hydrogenated petroleum resin; Described thinner is paraffin, ceresine, polyethylene wax, Fischer-Tropsch wax; Described recessed soil is original soil or modified attapulgite: the recessed soil of viscosity, brighten recessed soil, the recessed soil of acidifying; Described oxidation inhibitor is 2,6-di-tert-butyl-4-methy phenol that is 264 or four [β-(3 ', 5 '-di-t-butyl-4 '-hydroxy phenyl) propionic acid] pentaerythritol ester that is 1010; The VA% of described matrix resin is 5-40, and melting index is 15-400.
Description
Technical field
The present invention is specifically related to a kind of recessed native hot melt adhesive and preparation method thereof.
Background technology
Ethylene-vinyl acetate copolymer (EVA) based hot melt adhesive, can be widely used in the 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 relatively high.One of means reduced costs are in component, add some fillers, conventional filler is: calcium carbonate, silicon powder, talcum powder, White Carbon black, lightweight White Carbon black, metal nitride, metal oxide etc., but the shortcoming of these fillers is or than great, easily sink to the bottom, disperse bad, otherwise too expensive.As UnitedStatesPatent6,750,55 give a kind of tackiness agent for semi-conductor, wherein containing metal nitride, metal oxide.
Summary of the invention
The object of the invention is recessed soil to add in hotmelt, a kind of new type hot-melt adhesive and preparation method thereof is provided, when ensureing that other performances do not reduce, tackifying, gain in strength, reducing costs.
Hot melt adhesive composition of the present invention is: matrix resin: 20-50%; Tackifying resin: 20-50%; Thinner: 10-30%; Recessed soil: 2-40%; Oxidation inhibitor: 0.1-1%.
Described matrix resin is ethene and vinyl acetate copolymer eva, or itself and ethene and butyl acrylate copolymer EMA, ethene one acrylic copolymer EAA, ethylene ethyl acrylic copolymer EEA, vinylbenzene and isoprene copolymer SIS, copolymer from styrene and butadiene SBS, any one or more in amorphous alpha-olefin polymers APAO combine and add, wherein the VA% of matrix resin is 5-40, and melting index is 15-400.
Described tackifying resin can be rosin, polymerized rosin, 145 resins, 138 resins, terpine resin, petroleum resin or hydrogenated petroleum resin;
Described thinner can be paraffin, ceresine, polyethylene wax, Fischer-Tropsch wax;
Described recessed soil is former recessed soil or the recessed soil of viscosity, brightens the modified attapulgites such as recessed soil;
Described oxidation inhibitor be 264 (2,6-di-tert-butyl-4-methy phenol) or 1010{ tetra-[β-(and 3 ', 5 '-di-t-butyl-4 '-hydroxy phenyl) propionic acid] pentaerythritol ester }
Preparation method of the present invention is:
First thinner is melted, then add matrix resin, when matrix resin melts substantially, add tackifying resin gradually, react 0.5-1.5h at 130-180 DEG C after, add recessed soil and oxidation inhibitor, then react 0.5-1h discharging, shaping, granulation, obtain product of the present invention.
Advantage of the present invention is:
1, add recessed soil and significantly can reduce product cost;
2, add recessed soil and can improve product viscosity and softening temperature;
3, add recessed soil and can increase product bonding strength;
4, add recessed soil and add other fillers and compare, its suspension is good, does not precipitate, and viscosity is large, is easily uniformly dispersed, and is conducive to hot melt adhesive performance and improves.
Embodiment
Embodiment:
By the paraffin of 10%, the ceresine fusing of 9.8%, then adds the EVA of 35%, when EVA melts substantially, adds 45%145 gradually
#tackifying resin, adds 1010 oxidation inhibitor of 0.2%, then reacts 0.5h discharging, obtain basic product at 150 DEG C after reacting 1h.
Get above-mentioned basic product 95 parts, add former recessed native 5 parts and form.
