Abstract
The invention discloses antistatic resin comprising polypropylene and antistatic agent, wherein the polypropylene consists of polypropylene A with the melt index being 31-75 and polypropylene B with the melt index being 0.5-30; the antistatic agent consists of polyethylene glycol and sodium alkane sulfoate; and all the components are in the following part ratio: 50-98 parts of polypropylene A, 2-50 parts of polypropylene B, 6-8 parts of polyethylene glycol and 6-10 parts of sodium alkane sulfoate. The antistatic resin provided by the invention has favorable antistatic property, and the half life of static is less than 10 seconds.
Description
Technical field
The present invention relates to a kind of antistatic resin.
Background technology
Polypropylene fibre is hydrophobic fibre, when the neutralization of its course of processing is stood to rub by its textiles of making, easily produces accumulation of static electricity, the easy dust suction of the clothes of making and disagreeable electric-shock feeling is arranged, and dress is uncomfortable, thereby the antistatic property of raising polypropylene fiber is very necessary.Solve three approach of the general employing of antistatic problem: (1) surface preparation, namely with static inhibitor, fiber or textile fabrics are carried out dip treating, this method is easy, and cost is low, but its antistatic property is often decayed with washing; (2) adopt Compound spinning, another component is for having conductivity, but cost is more expensive, complex process; (3) adopt anti static additive, but usually because general static inhibitor adds, the rheological variation that can cause polymkeric substance, the fibre machinery degradation, thereby can not spin out thin dawn superfine Denier fibre, and thin dawn and polypropylene fiber in carding process can be given textiles and lead wet, ventilative, snugness of fit, thus the added value of raising fabric.
Summary of the invention
Goal of the invention of the present invention is: for the problem of above-mentioned existence, provide a kind of antistatic resin, resin of the present invention has good static resistance, electrostatic half-life＜20 second.
To achieve these goals, the present invention adopts following technical scheme:
A kind of antistatic resin, formed by polypropylene and static inhibitor, described polypropylene is that the polypropylene A of 31-75 and polypropylene B that melting index is 0.5-30 form by melting index, described static inhibitor is comprised of polyoxyethylene glycol and alkyl sodium sulfonate, the portion rate of each component is as follows: polypropylene A50-98 part, polypropylene B2-50 part, polyoxyethylene glycol 6-8 part, alkyl sodium sulfonate 6-10 part.
The molecular weight of described polyoxyethylene glycol is 2000-30000.
Described alkyl sodium sulfonate is the alkyl sodium sulfonate of C12-16.
The portion rate of each component is as follows: polypropylene A65 part, polypropylene B35 part, 7 parts of polyoxyethylene glycol, 9 parts of alkyl sodium sulfonates.
In the present invention, alkyl sodium sulfonate is a kind of ionic surface-modifying agent; it is comprised of hydrophobic group and hydrophilic radical; its hydrophobic grouping is combined with polypropylene matrix; hydrophilic radical combines with polyoxyethylene glycol; make polypropylene matrix interface formation protective layer; improve the electric charge translational speed, therefore improved static resistance and the anlistatig stability of fiber.
The present invention has the following advantages:
1. adopt the composite static inhibitor with suitable molecular weight, make the fiber and its products antistatic effect lasting, wash 50 times, its static resistance still remains in electrostatic half-life＜20 second.
2. adopt the polypropene blended of different melting index, add the static inhibitor that can improve rheological, make mixture have enough mobility in spinning process, can spin thin dawn and polypropylene fiber in carding process fiber.
3. the tensile strength of fiber greater than 3.5 lis of newton/dtexs, can be carried out routine and high speed spinning, and technology controlling and process is easy, and textile process is smooth.
