This special agricultural Anti drip polyvinyl chloride film has excellent thermal stability and long-lasting ,anti-fogging ability.
The film comprises l00 parts of polyvinyl chloride, 0.01-0.7 part of fluorocarbon surfactant, 0.3-10 parts of organic phosphorus compound
Anti-fog agent 0.8 to 5 parts.
The detail specification formula (parts by mass):
PVC (d.P.1300) 100
Megafac Fl42 D 0.3
Epoxy resin 2
(R1 ~ 4 = phCH2) 1
Ba-Zn Stabilizer 2.5
Sorbitan monostearate l
Sorbitan monopalmitate l
The above components are mixed and molded into a 0.1 mm thick film. Agricultural films with drip-proof and anti-fog Performance .
, This agricultural film water absorption layer (made of thermoplastic polyoxyethylene polymer, the average molecular weight of 10,000 to 300,000)
And non-water-absorbing thermoplastic polymer containing anti-drip and anti-fogging agents. Fluorocarbon surfactants can be used as anti-fogging agents and anti-drip
(2) Transparent anti-fog Fiber film ,with wetting ability and anti-fogging , the surface were modified by fluorocarbon surfactant Agent. Fluorocarbon surfactant form a monolayer which covering the surface of the fiber membrane, the modification effect is more better than the non-fluorosurfactant
It is could be evidenced by the contact angle and Zisman curve of water drop on the surface). The Films (fluorocarbon surfactant added)
Which be placed in a room full of water vapor (60 ℃), the experiment proved the film surface no fog in long time and remain transparent. Anti-fogging function from the fluorocarbon Monolayers which made from fluorocarbon surfactants consisting of chains and non-ionic oxyethylene chains.
