Problems solved by technology

[0008] The second technical problem mainly solved by the present invention is that the dust-proof effect of the polyolefin shed film is mainly obtained by internally adding additives, while the dust-proof effect of the internally added dust-proof shed film will migrate to the surface of the shed film along with the auxiliaries. Rain and wind erosion and other left and right gradually disappear from the surface, thus affecting the continuous dustproof effect of the shed film

Embodiment 1

[0076] The molecules with dustproof effect used in the present invention are all self-made. The schematic diagram of the chemical structure is shown in formula (V). In the formula (V), n represents the number of repeating units of oxyethylene, and the allyl polyoxyethylene ether (selected from McLean's reagent ), using it as a raw material to prepare the corresponding dust-proof monomer.

[0077] Wherein the preparation method is as follows:

[0078] Allyl polyoxyethylene ether, acetic acid and chloroplatinic acid were mixed in a mass ratio of 70:20:10 and prepared into a 20 wt% isopropanol solution. Add the reaction kettle, then raise the temperature to 70°C and stir for 1 hour. Raise the temperature to 85°C, add heptamethyltrisiloxane dropwise, the molar ratio of methylsiloxane to allyl polyoxyethylene ether is 3:2, control the dropping rate at 40g / min, and control the temperature of the reaction solution at Below 100°C, the dropwise addition is completed in about 3 hours...

Embodiment 2

[0082] The ionic polymer used in the present invention is produced by DuPont Company, and the trade mark is Surlyn 1601-2. The initiator used in the present invention is 2,5-dimethyl-2,5-di-tert-butylperoxyhexane (double 25), which is an analytically pure product of Bailingwei Technology Co., Ltd.

[0083] Disperse the initiator in the n=0 molecules with anti-dust effect synthesized by this patent shown in formula (V), and prepare a mixed solution in which the initiator accounts for 5% of the mass fraction of the anti-dust molecules. A co-rotating twin-screw extruder (screw diameter 20mm, aspect ratio 40) from Sweden LabTech Company was selected. The mixed polyolefin particles (Surlyn 1601-2), and the mixture of molecules with dustproof effect and initiator are mixed, plasticized, reacted, and extruded. The feeding speed of polyolefin particles (Surlyn 1601-2) is 10kg / h, and the feeding rate of the mixed solution of molecules with dustproof effect and initiator is 500g / hr to ...

Embodiment 3

[0086] The ionic polymer described in Example 2 and bis-2-5 are dispersed in the molecules with dust-proof effect of n=1 synthesized by this patent shown in formula 1, and the initiator accounts for the dust-proof molecular mass fraction of 5% mixture. A co-rotating twin-screw extruder (screw diameter 20mm, aspect ratio 40) from Sweden LabTech Company was selected. The mixed polyolefin particles (Surlyn 1601-2), the mixture of molecules with dustproof effect and initiator are mixed, plasticized, reacted, extruded, and the feeding speed of polyolefin particles (Surlyn 1601-2) 6-10kg / h, the feeding speed of the mixture of molecules with dustproof effect and initiator is 500g / hr, and the dustproof modified ion polymer material is made.

[0087] The extruder has 11 sections from the feed port to the die, numbered 1-11, and the first section only plays the role of feeding and cannot be heated. The temperatures of sections 2-11 of the extruder are respectively: 150°C, 160°C, 170°C...

Abstract

The invention relates to a dustproof ionic polymer, a preparation method of the dustproof ionic polymer and a dustproof greenhouse film, the dustproof ionic polymer comprises an ionic polymer and dustproof molecules fixed on the ionic polymer through chemical bonds, the ionic polymer is applied to an agricultural greenhouse film, molecules with a dustproof effect are fixed on the ionic polymer in a chemical grafting reaction form, so that the dustproof effect of the prepared greenhouse film can be kept for a long time, and meanwhile, the greenhouse film has relatively high light transmittance. The good technical effect is achieved, and the existing technical problem is well solved.

Description

technical field [0001] The invention relates to a dust-proof ionic polymer material, in particular to a dust-proof ionic polymer, a preparation method thereof and a dust-proof shed film. Background technique [0002] Ionic polymers are referred to as ionomers, also known as ionomers, which refer to macromolecular main chains containing a small amount of ionizable groups (the molar content of ionic groups is not more than 15%), and are partially neutralized by metal ions Or fully neutralized salt-forming polymers. Since ionomers have metal ionic bonds in addition to covalent bonds, they can "apparently cross-link" adjacent polymers, and the polarities of ionic groups and hydrocarbon main chains are very different, the general tendency In the formation of its enriched region - ion clusters. [0003] Compared with traditional polyethylene materials, at close molecular weights, ionomers tend to have better mechanical properties and excellent antistatic properties, stronger ela...
