Abstract

The invention discloses a hydrophilic antistatic polypropylene composition and a preparation method and application thereof. The composition is prepared from the following components in parts by weight: 30-75 parts of polypropylene, 0.5-15 parts of compatilizer, 2-25 parts of hydrophilic accelerant and 5-70 parts of hydrophilic agent, wherein the hydrophilic agent comprises a non-ionic surface active agent and an anionic surface active agent. The composition also includes optionally a dispersant, a lubricant, and an antioxidant. The obtained hydrophilic antistatic material can be used as a master batch to be directly added into polypropylene resin for melt spinning, the obtained polypropylene non-woven fabric is good in hydrophilic performance, capable of absorbing multiple times of wateramount of the non-woven fabric and short in penetration time, and good hydrophilicity can still be kept after multiple times of scouring, and the material has scouring resistance and durable hydrophilic effects. The product prepared by the method also has an excellent antistatic effect and is simple in preparation process and low in cost and is beneficial to large-scale commercial production.

Description

Technical field [0001] The invention belongs to the technical field of polymer materials, and specifically relates to a hydrophilic antistatic polypropylene composition and a preparation method and application thereof. Background technique [0002] As one of the five general-purpose plastics, polypropylene is cheap and has excellent mechanical properties. It is widely used in various fields. Among them, polypropylene fiber is resistant to tensile deformation and has high breaking strength and elongation. The resulting meltblown non-woven fabric has the characteristics of fluffy, softness, and good strength. In recent years, it has been regarded as an ideal material for the manufacture of high-end sanitary napkins, baby diapers and adult incontinence products. However, polypropylene fiber has a non-polar structure and has limitations such as hydrophobicity or poor hygroscopicity. Generally, the contact angle of meltblown non-woven fabrics is greater than 80°, which makes it diffic...
