preparation example 1

[0035] The barrier layer is a three-layer co-extruded high barrier composite film with a thickness of 50 microns. The three-layer co-extruded high-barrier composite film is composed of a 15-micron first modified PET film, a 20-micron intermediate reinforced barrier film, and a 15-micron second modified PET film. Both the first modified PET film and the first modified PET film are prepared from the following raw materials in mass percentage: 2% TPEE thermoplastic polyester elastomer (DuPont TPEE-5526), ​​20% polyethylene naphthalate Alcohol resin (brand name TN8065S, American DuPont Company), 1% antioxidant 1010, 77% PET resin (brand name: RE19045BK, American DuPont Company).

[0036] The intermediate reinforced barrier film is prepared from the following raw materials: 3% TPEE thermoplastic polyester elastomer (DuPont TPEE-5526), ​​20% LCP resin (grade A950, Celanese Corporation), 15% polynaphthalene Formic acid ethylene glycol resin (brand name TN8065S, U.S. DuPont Company),...

Abstract

The invention relates to the technical field of pesticide packaging plastics, in particular to a high-barrier pesticide packaging bottle and a preparation method thereof. A high-barrier pesticide packaging bottle comprises an inner base layer, a first binder layer, a barrier layer, a second binder layer and an outer layer, and the barrier layer is a three-layer co-extrusion high-barrier composite film; the three-layer co-extrusion high-barrier composite film comprises a first modified PET film, a middle reinforced barrier film and a second modified PET film; the middle reinforced barrier film is prepared from the following raw materials: TPEE (thermoplastic polyester elastomer), LCP (liquid crystal polymer) resin, polyethylene naphthalate resin, PET (polyethylene terephthalate) resin, an antioxidant and filler. The high-barrier pesticide packaging bottle prepared by the invention has good gas barrier property and good barrier property on hydrocarbon solvents, and is suitable for storing various liquid pesticides taking hydrocarbons such as benzene, toluene, xylene and gasoline as solvents.

Description

technical field [0001] The present application relates to the technical field of pesticide packaging plastics, in particular to a high-barrier pesticide packaging bottle and a preparation method thereof. Background technique [0002] Pesticide packaging bottles are mainly divided into three categories according to different preparation materials: glass bottles, metal bottles and polymer material bottles. Among them, glass bottles are prone to breakage during transportation and have been gradually eliminated; metal bottles are relatively expensive and susceptible to corrosion, making it difficult to promote and apply them on a large scale. At present, the mainstream pesticide packaging bottles are still mainly made of polymer materials, and the polymer materials mainly include HDPE, PE, PP, PET and so on. [0003] Polyethylene terephthalate PET is a crystalline polymer material with very high melting temperature (Tm=265°C) and glass transition temperature (Tg=65°C). PET pol...
