Abstract
The invention discloses a PP (polypropylene) meltblown special composite material and a preparation process thereof. The PP meltblown special composite material is characterized by being mainly prepared from nanometer calcium carbonate, surface treating agent, POE (polyolefin elastomer), polypropylene and polyisobutylene with the weight ratio of (95-110) : (1-2) : (4-6) : (58-62) : (1-3). The PP meltblown special composite material disclosed by the invention has good filtration performance, good spinnability, no slurry drip, good coloring performance, uniform lapping, normal gram weight, good tensile strength and flexible performance, good surface gloss and good application value.
Description
Technical field
The present invention relates to PP melt spraying non-woven fabrics technical field, relate in particular a kind of PP melt spraying non-woven fabrics matrix material and preparation technology.
Background technology
The quality and performance of melt spraying non-woven fabrics depends on the selecting properly of pp material (melting index) and the optimization of processing conditions.At present, what melt and spray that producer mainly adopts is the pp material that height melts finger, but lacks necessary handiness to adapt to the different market requirements, also exists simultaneously expensive pressure.In the nineteen forty-six invention, the product main application fields has the melt-blown process of very early time by Van Mr. Vente: filter, the fibre web uniformity coefficient is had relatively high expectations; Isolation, higher to the continuous coherence request of fibre web, wire side can not have broken hole or not have the good agglomerate of drawing-off to occur; Warming, high to the fluffiness requirement of fibre web.Wire side has broken hole or occurs not having the agglomerate of drawing-off will reduce the total quality of fibre web, melt and spray the fritter film that " shot " usually said in the product just refers to not pass through drawing-off, regional fast more than other in the regional water seepage velocity that " shot " occur, this fault can check by measurement hydrostaticpressure height.Therefore, one that how further improves the hydrostaticpressure height that spins molten product and be product design and development pursues a goal, on the one hand can be by the improvement to production process control, such as the optimization to device parameter and production stage, avoid that agglomerate appears in fiber in the fibre web; Start with from the feed change quality on the other hand, for this reason, be necessary the matrix material that non-woven fabrics uses is carried out more research work, prepare the PP melt spraying non-woven fabrics composite material special of advantages such as a kind ofly having that lapping is even, grammes per square metre normal, tensile strength, softness are good.
Summary of the invention
Purpose of the present invention is exactly that a kind of not only strainability that provides for the deficiency that solves prior art is good, good spinnability, do not drip slurry, tinctorial property is good, lapping is even, grammes per square metre is normal, tensile strength, softness is good, surface gloss is good, and has the PP melt spraying non-woven fabrics composite material special of environment-friendly function.
Another object of the present invention provides a kind of preparation technology of PP melt spraying non-woven fabrics composite material special.
The present invention adopts following technical solution to realize above-mentioned purpose: a kind of PP melt spraying non-woven fabrics composite material special, it is characterized in that, it is mainly made by nano-calcium carbonate, surface treatment agent, POE, polypropylene and polyisobutene, and the weight ratio of nano-calcium carbonate, surface treatment agent, POE, polypropylene and polyisobutene is (95-110): (1-2): (4-6): (58-62): (1-3).
As further specifying of such scheme: the preferred 100:1.5:5:60:2 of the weight ratio of described nano-calcium carbonate, surface treatment agent, POE, polypropylene and polyisobutene.
The particle diameter of described nano-calcium carbonate is the 4500-5500 order, and surface treatment agent is end amino polybasic alcohol ester.
A kind of preparation technology of PP melt spraying non-woven fabrics composite material special is characterized in that it comprises the steps:
A, nano-calcium carbonate is added in horizontal double helical ribbon mixer first, the heating middling speed was mixed 25-35 minute;
B, add surface treatment agent, high-speed mixing 10-20 minute;
C, add POE and polypropylene, high-speed mixing 5-15 minute;
D, by screw feeding machine, the mass transport that mixes is to continuous internal mixer material storage tank;
E, by the powder metering feeding machine, feeding is to continuous internal mixer;
F, polyisobutene is added to the liquid meter feeding machine, feeding is to continuous internal mixer;
G, extruding pelletization;
E, finished product packing.
In described processing step a process, described mixed powder water content＜2%.
In described processing step a process, heating mixed 30 minutes.
In the high-speed mixing process of described processing step b, treatment agent is wanted complete coated powder.
In described processing step b process, high-speed mixing 15 minutes.
In described processing step c process, high-speed mixing 10 minutes.
The beneficial effect that the present invention adopts above-mentioned technical solution to reach is:
1, this matrix material of the present invention by original PP Production Technology, is fully normally produced on the melt spraying non-woven fabrics machine.
2, good, the good spinnability of strainability, do not drip slurry, tinctorial property is good, lapping is even, grammes per square metre is normal, tensile strength, softness is good, surface gloss is good.
3, reach environment-friendly function.
