Description
Technical field
The present invention relates to a kind of continuous preparation method and equipment of hot melt adhesive, belong to the hot melt adhesive preparing technical field.
Background technology
Thermosol (abbreviation hot melt adhesive) typically refers to and at room temperature is solid-state, and it is liquid that heating and melting becomes, and behind coating, the wetting adherend, through pressing, cooling, finished bonding sizing agent in the kind at several seconds.Have curing speed soon, advantage such as not moisture and other solvents, be widely used in industries such as packing, printing, clothes and electronics.
The preparation method of hot melt adhesive adopts the melting mixing method usually, generally is divided into two kinds of interrupter method and continuous processings, and the former mainly is that the still formula is produced, and the latter mainly is extrusion molding production.It is each component of a certain amount of sizing agent to be pulverized the back adding have in the mixing kettle of stirring that the still formula is produced, the heating and melting and the back discharging that stirs, and then make second batch, its production efficiency is not high, and thermooxidative degradation easily takes place the hot melt adhesive component.Extrusion-type production is that each component of sizing agent is sent in the airtight forcing machine that is heated to certain temperature after pulverizing and tentatively mixing continuously, and fusion also mixes, and is extruded by screw rod continuously then.But because the various feed composition density variations of preparation thermosol are bigger, each component blanking speed difference, inhomogenous problem can appear in the material that enters forcing machine.In addition, the low-melting component in the raw material is in blanking channel or have the screw front end of certain temperature promptly to melt, and causes the uneven even obstruction cutting agency of blanking.If at first with each component of sizing agent raw material through mixing roll or the mixing forcing machine that enters again of reactor, on the one hand, technology is loaded down with trivial details, on the other hand, through mixing semi-product material malleable chemical property in transfer way, more than these reasons all can cause the quality problems and the production efficiency of hot melt adhesive.
But, carried out the improvement of many technologies in order to prepare the second best in quality hot melt adhesive product of continuous production.Patent CN 101264659A and U.S.P.No 4337721 disclose a kind of forcing machine equipment of processing hot melt adhesive, all be to increase by a vertical feeding unit at forcing machine charging opening place, can make each component of hot melt adhesive raw material thorough mixing before entering forcing machine, charging is even.But this method all has problems when producing the product of tackifier or liquid starting material large usage quantity.The fusing point of general tackifier is all lower, and as tackifier large usage quantity in hot melt adhesive, when producing, the tackifier that enter in the forcing machine can be melted in the screw flight, cause buildup, make the product of extruding inhomogeneous, quality problems occur.Using continuous processing to produce this hot melt adhesive needs forcing machine should make each feed composition thorough mixing of hot melt adhesive even, and extruder screw also needs good automatically cleaning ability.Patent U.S.P.No 4300839 discloses a kind of self-cleaning type forcing machine, this forcing machine has the screw rod of special shape, can solve the automatically cleaning problem of screw rod, and can make each material thorough mixing, but this forcing machine is not applied to the production of hot melt adhesive, and the forcing machine that needs special construction, technology are complicated.
The above-mentioned the whole bag of tricks of mentioning all can not solve a present the second best in quality hot melt adhesive quantity-produced difficult problem.
