Abstract

The invention discloses a production method of an anti-dropping plastic film, which is characterized by containing ingredients by weight: 100 parts of linear low density polyethylene (LLDPE), 15 parts of anti-dropping master batches, 0.25-0.35 part of plastic fluorescent whitening agents 0B-1, 0.1-0.3 part of dispersing agent ethylene bis stearamide, 0.01-0.02 part of photosensitizer iron stearate and 0.2-0.4 part of antifoggant sorbide monostearate. All the ingredients are dried in an oven at temperature of 50 DEG C before being used, then stirred for 20min in a high-speed stirrer with temperature controlled to be 110 DEG C-120 DEG C, added in an extruder after stirring in operation conditions of temperature being 150 DEG C-160 EEG C, and performed by a blow molding machine to obtain a product. The temperature at an outlet of the blow molding machine ranges from 170 DEG C to 175 DEG C. The anti-dropping performance is that time of an initial drip is 440s and time of ten drips is 122s. Light transmittance is 88%, and high temperature duration is 41d. The product has the characteristics of high light transmittance, high heat preservation, strong toughness, free of droplet hanging and the like.

Description

A kind of nothing is dripped the plastics film working method
Technical field
The present invention relates to a kind of nothing and drip the plastics film working method, belong to agricultural technology field.
Background technology
China is large agricultural country, and therefore the demand to agripast canopy film is huge, in recent years, consume more than 1,100,000 tons every year, and be the main production means of agriculture prodn.Ordinary agricultural membrane is in agriculture use, because the booth internal-external temperature difference is big, therefore often condenses the globule at the booth inwall, and forms vaporificly, has had a strong impact on the transmittance of booth, has weakened photosynthesis of plants, influences plant-growth; In addition, globule cohesion also can drop onto on the farm crop on the booth, and the disease and pest that brings out farm crop takes place, and causes seedling rot.Thereby the functional farmland film of the ageing-resistant anti-droplet of Development and Production becomes the task of top priority, developed and widely applied multi-functional ageing-resistant antifog non-drop plastics film abroad.
Do not have to drip plastics film in use, component wherein has loss in various degree, therefore uses deleterious after a short period of time.The nothing phase of dripping of present common non-drop greenhouse film was generally 4-6 month, and life-span 10-12 month, that grows most reached about 18 months.Development and Production does not have and drips a long-lived canopy film and obviously have very big economic benefit and social benefit, to promoting China's agricultural development, increase that the peasant receives the people, the vegetables-basket that enriches people has very important effect that research and development do not have the plastics film of dripping and have development potentiality.
Summary of the invention
Technical problem to be solved by this invention is that the deficiency that is directed against prior art provides a kind of nothing to drip the plastics film working method.
There is not the plastics film working method of dripping; By 100 parts of (weight parts; LLDPE (LLDPE), 15 parts of dripless masterbatch (mould scientific and technological development ltd by Jinan three and produce, full name is " a long-lived dripless masterbatch "), plastics white dyes OB-1 consumption 0.25-0.35 part, dispersion agent ethylene bis stearamide 0.1-0.3 part, photosensitizers iron stearate 0.01-0.02 part, antifogging agent sorbitan monostearate 0.2-0.4 part batching down together).Above-mentioned batching is dried down at 50 ℃ in baking oven earlier before use.To prepare burden and in impeller, stir 20min, and the temperature in the control stirrer is 110-120 ℃.After stirring end batching is joined forcing machine, forcing machine operational condition: temperature 150-160 ℃, make product through blow moulding machine again, 170-175 ℃ of blow moulding machine temperature out.
The anti-fogging property ability:
Just drip time: 440s; 10 time: 122s; Transmittance: 88%; The high temperature lasting period: 41d.
Products characteristics:
High transmission rate, high insulation; Toughness is strong; Do not hang the globule etc.
