Abstract
The invention adopts the melt-blown soft master batch which comprises the following components in percentage by mass: 2-10 parts of a softening agent; 3-10 parts of a lubricant; 8-16 parts of a dispersing agent; 0.1-0.5 part of antioxidant 1010; antioxidant 168, 0.5-1 part; elastomer, 5-10 parts; initiator 05-3 parts; 50-70 parts of polypropylene. The invention also provides a melt-blown softening master batch, which improves the formula and adopts a softening agent, a lubricating agent, a dispersing agent, an antioxidant and an elastomer with low melting index. Because the melt finger is too high and is not matched with the melt finger of the carrier melt-blown special material in the actual production of the non-woven fabric, the elastomer with lower melt finger is added to reduce the melt finger and simultaneously increase the viscosity and the toughness, and the melting point of the elastomer is lower than that of polypropylene, so the elastomer can be completely melted in the actual granulation production.
Description
Technical Field
The invention relates to a melt-blown soft master batch and a preparation method thereof.
Background
The melt-blown non-woven fabric is made up by directly forming web with polymer, making the high polymer melt extruded from screw extruder pass through high-speed high-temp. air-flow blowing or other means (for example centrifugal force and electrostatic force), making the melt trickle undergo the process of extremely-stretching to form superfine short fibre, then gathering the short fibre on the web-forming drum or web-forming curtain to form web, finally making the above-mentioned material undergo the process of self-bonding treatment to obtain the invented non-woven fabric.
The melt-blown soft master batch is a master batch special for melt-blown non-woven fabrics, most of the materials on the market at present are produced by mixing the melt-blown soft master batch with a special material for melt-blowing, but the common melt-blown master batch used for the special material for melt-blowing in the production process of the non-woven fabrics can cause incompatibility of the master batch and a carrier melt finger, thereby causing a series of conditions such as blockage of a spinning nozzle.

The invention has the beneficial effects that: the formula is improved by adopting a softening agent, a lubricating agent, a dispersing agent, an antioxidant and an elastomer with low melting index. Because the melt finger is too high and is not matched with the melt finger of the carrier melt-blown special material in the actual production of the non-woven fabric, the elastomer with lower melt finger is added to reduce the melt finger and simultaneously increase the viscosity and the toughness, and the melting point of the elastomer is lower than that of polypropylene, so the elastomer can be completely melted in the actual granulation production. In addition, the melting finger of the special material for melt-blown produced by melt-blown non-woven fabric is generally about 1500-1600, and is matched with the melting finger, and the melting finger of the melt-blown soft master batch is made into the melting finger. For such melt index, in the process of producing master batch, because the melt flow property is too good, the uniformity of master batch particle size is difficult to reach, so the method needs to be improved, wherein the zone 1-2 is a feeding section, the temperature is not too high, the temperature is reduced to enable the master batch to be fed smoothly, auxiliary agents are not melted due to different melt indexes of the mixture, and the carrier material is still the original shape. The 3-6 zones are the melting zone, in which the material must be sufficiently melted. The 7-10 area is a material mixing section, the temperature of the material mixing section is basically equal to the melting point of the carrier resin, so that the fluidity of the material mixing section has certain friction force to uniformly mix the materials. The 11-zone machine head is an extrusion zone, the temperature of the zone must be lower than the melting point of the material, because the high melting point means that the flow property of the melt of the material at high temperature is very good and is approximately liquid, the material can not be subjected to the pressure of uniform extrusion at the die head, the discharge hole below the die head can discharge more material, and the discharge hole above the die head discharges less material or does not discharge material, thus causing the problem of quality due to different particle sizes. It must be below the melting point of the carrier resin in the extrusion zone so that it is uniformly subjected to the pressure exerted by the material being rotated by the screw.
