【摘要】：用表面活性劑對(duì)聚乙烯(PE)樹(shù)脂進(jìn)行改性,制備防霧薄膜,使其具有防霧作用。以聚乙烯蠟乳液(WE1)為分散劑,防霧母粒(YS)、聚甘油脂肪酸酯(PGFE)作為防霧劑,對(duì)PE樹(shù)脂進(jìn)行改性,混合造粒后流延制備出聚乙烯防霧薄膜。研究了改性聚乙烯薄膜的微觀結(jié)構(gòu)、防霧性能、力學(xué)、光學(xué)、透氣、透濕及熱穩(wěn)定性能。結(jié)果表明,防霧劑與聚乙烯薄膜相容性好,改善了聚乙烯薄膜的阻隔性,并且使薄膜具有優(yōu)良的防霧性能。YS的加入使薄膜拉伸強(qiáng)度增大,當(dāng)YS,PGFE分別以2%復(fù)配時(shí),薄膜透光率為86.22%,拉伸強(qiáng)度為8.63 MPa,斷裂伸長(zhǎng)率為453.31%,高溫防霧時(shí)間可達(dá)232h,可以作為防霧包裝薄膜使用。
[Abstract]:The antifogging film was prepared by using surfactant to modify PE resin. Polyethylene wax emulsion WE1) was used as dispersant, anti-fogging masterbatch was used as anti-fogging agent, and polyglycerol fatty acid ester (PGFE) was used as anti-fogging agent to modify PE resin. Polyethylene antifogging films were prepared by mixed granulation. The microstructure, antifogging properties, mechanics, optics, air permeability, moisture permeability and thermal stability of modified polyethylene films were studied. The results showed that the antifogging agent had good compatibility with polyethylene films. The barrier property of polyethylene film was improved, and the addition of YS made the film have good antifogging property. The tensile strength of the film was increased. When the YS- PGFE was mixed with 2% respectively, the tensile strength of the film was increased with the addition of YS. The film has a transmittance of 86.22m, a tensile strength of 8.63 MPa, an elongation at break of 453.31 and a high temperature antifogging time of 232h. it can be used as an antifogging packaging film.
