Problems solved by technology

[0003] Agricultural films are widely used in agricultural production, but conventional agricultural films have poor moisture permeability and air permeability, and the anti-fog effect is not ideal
When the sun shines for a period of time, the air humidity in the greenhouse rises obviously. When the humidity of the weather itself is relatively high, it is easy to cause damage to the crops by using this kind of film with poor moisture permeability.

Embodiment 1

[0039] 50 parts of HDPE, 1 part of 80-mesh medical stone powder, 0.01 part of bis(2,2,6,6-tetramethyl-4-piperidinyl) sebacate, 0.2 part of 1,1,3- Tris(2-methyl-4-hydroxy-5-tert-butylphenyl)butane and 0.1 part of mold release agent are extruded and granulated through an extruder, and the obtained granules are blown to prepare a single-layer functional film.

[0040] The obtained sample was tested, and the absorbance was 0.122, it was fogged after 4 seconds, and the conductivity was 3.1 μs / cm.

Embodiment 2

[0042] 60 parts of HDPE, 40 parts of PP, 20 parts of 80 parts of medical stone powder treated with silane coupling agent KH-550, 5 parts of bis(2,2,6,6-tetramethyl-4-piperidine Base) sebacate, 3 parts of 1,1,3-tris(2-methyl-4-hydroxy-5-tert-butylphenyl)butane are extruded and granulated through an extruder, and the resulting pellets are passed through a stream The single-layer functional film is stretched, and the obtained film is uniaxially stretched.

[0043] The obtained sample was tested, and the absorbance was 0.009. After 7 seconds of fogging, the conductivity was 17.7 μs / cm, and there was no insect repellent effect.

Embodiment 3

[0045] 80 parts of HDPE, 1 part of 100 mesh medical stone powder, 1 part of 80 mesh medical stone powder, 0.2 part of bis(2,2,6,6-tetramethyl-4-piperidinyl) sebacate , 0.1 part of benzophenone, 0.2 part of 1,1,3-tris(2-methyl-4-hydroxy-5-tert-butylphenyl)butane, 0.1 part of 2,2'-di-p-hydroxyphenylpropane , 0.1 part of release agent is extruded and granulated through an extruder, and the obtained pellets are extruded to obtain a single-layer functional film.

[0046] The obtained sample was tested, and the absorbance was 0.115, and the conductivity was 4.6 μs / cm.

Abstract

The invention discloses a composition, its functional film and a preparation method of the film. The composition includes 50-100 parts of base resin, 0-15 parts of compatibilizer, 1-20 parts of medical stone, 0-20 parts of filler, 0-10 parts of functional microcapsules, 0.01-5 parts of ultraviolet light absorber, Antioxidant 0.2-3 parts. The above ingredients are extruded and granulated by an extruder, and the obtained pellets are made into a single-layer functional film by casting, film blowing, and extrusion, and the obtained different pellets are made by co-extrusion. Layer functional film; stretching the obtained film in one direction or in multiple directions can obtain a functional film with better moisture permeability and air permeability, better anti-fog performance, better dissolution of beneficial elements, antibacterial and insect repellent effects.

Description

technical field [0001] The invention relates to a composition, a functional film prepared by the composition and a preparation method of the functional film, belonging to the field of macromolecules. Background technique [0002] Medical stone is a natural medicinal ore, containing potassium, sodium, calcium, magnesium, phosphorus, zinc, iron and other large elements, and can dissolve a large number of beneficial elements under the action of water extraction. At the same time, medical stone has a sponge-like porous structure, which has a good adsorption effect on harmful elements such as cadmium and lead, and also has a high adsorption rate on bacteria such as E. coli, which can play a good antibacterial effect. Adding medical stone powder to polymer materials can effectively improve the wettability of the material to water, thereby reducing the possibility of fogging on the surface of the material. [0003] Agricultural films are widely used in agricultural production, but...
