Summary of the invention
In order to address the above problem, the present inventor has conducted intensive studies, and final design has also been prepared a kind of thermoplastic polyurethane foamex viscose glue, thereby has completed the present invention, and has solved to a great extent above-mentioned drawback.
The goods that the object of this invention is to provide a kind of thermoplastic polyurethane foamex viscose glue, its preparation method, purposes and comprise this thermoplastic polyurethane foamex viscose glue.Thermoplastic polyurethane foamex viscose glue of the present invention makes full use of the physics and chemistry characteristic of wet type foaming PU resin, hot melt adhesive, parting agent, solvent, through fully mixing together.
According to an aspect of the present invention, provide a kind of thermoplastic polyurethane foamex viscose glue, its main component comprises according to weight part meter:
100 parts of wet type foaming PU resins;
Hot melt adhesive 40-60 part;
Parting agent 3-5 part; With
Solvent 0-200 part.
Wherein, wet type foaming PU resin is a kind of synthetic resins, is mainly formed by polyisocyanates and polyether polyol after chemical reaction.
In thermoplastic polyurethane foamex viscose glue of the present invention, wet type foaming PU resin plays the effect that produces sticking power, after mixing slaking with various types of materials, reach 2-3 expansion ratio doubly, make the finished product there is the effect that vacuum is adhered to, its kind is not limited, as long as can reach 2-3 expansion ratio doubly through mixing maturing process, make the finished product there is the effect that vacuum is adhered to.
Preferably, be used in the molecular weight that wet type in thermoplastic polyurethane foamex viscose glue of the present invention foaming PU resin can have 60000-140000, the preferably molecular weight of 80000-100000, viscosity is 12-18 ten thousand CPS/25 DEG C, preferably 160,000 CPS/25 DEG C, acid value is less than or equal to 12mgKOH/g, is preferably 7mgKOH/g, solid content is 30wt%～80wt%, preferably 30wt%～50wt%.
In concrete embodiment, the wet type foaming PU resin that is applicable to thermoplastic polyurethane foamex viscose glue of the present invention for example can mix with 1:1 with the HD-862 of urethane company limited of Dongguan HTC production and sales for the SR-662 of Dongguan City China fir Chemical Co., Ltd. production and sales; The RW-2202-1 that Ju Yang trade Co., Ltd of Xiamen City sells; The PUA-902 that Taizhou plain Huangyan He Cheng polyurethane product factory produces mixes with 2:1 with the R-240 that Ju Yang trading company of Xiamen City sells.
In the present invention, hot melt adhesive plays increases the mixture viscosity shortening production reaction times in process of production, increase and the effect of adhesion strength and stability (especially in the situation that temperature changes) of adhering to medium (for example ground) after production completes, enough above-mentioned effects its kind do not limited, as long as can be provided.Preferably, hot melt adhesive used in this invention can be ethene and acetate ethylene copolymer (EVA) hot melt adhesive, preferably there is the molecular weight of 1000-9000, the preferably molecular weight of 1000-5000,5.0-6.0 ten thousand mpa.s (Bu Shi) when 200 DEG C of viscosity numbers, density 1.45g/cm 25 DEG C time
