preparation example Construction

[0031] According to the present invention, figure 1 It is a schematic flow diagram of the preparation method of the compounding aid composition of the present invention, such as figure 1 As shown, the preparation method for preparing a compounding aid by using the compounding aid composition of the present invention comprises: drying, mixing and stirring the compounding aid composition (antioxidant, stabilizer and adhesion enhancer) , granulation / cutting, sieving, cooling, shaping, and packaging to obtain the compounding aid. Preferably, the mixing and stirring is carried out under high-speed stirring conditions.

[0032] Wherein, the drying conditions include: temperature 25-50° C., time ≥ 4 hours.

[0033] Stirring conditions include: mixing and stirring with a low-speed mixer for 15-30 minutes.

[0034] The conditions for sieving include: using a vibrating sieve with a sieve aperture of ≤5mm for sieving.

[0035] The conditions of setting treatment include: setting with...

Embodiment 1

[0063] This example is intended to illustrate synthetic resin and polyolefin films / sheets prepared using the compounding aid composition of the present invention.

[0064] Compounding Auxiliary Composition:

[0065] The antioxidant is a compound of hydroxylamine antioxidant and phosphite antioxidant, with a weight ratio of 1:1;

[0066] The stabilizer is hydrotalcite, D 50 ≤150nm, MgO / Al 2 o 3 3:1;

[0067] Adhesion enhancers are specifically: ɑ-nucleating agent (brand is NX8000K), β-nucleating agent (brand is MT205-B), petroleum resin (specifically hydrogenated C9) and synergistic anti-blocking agent (specifically silicon dioxide) compound , The weight ratio of α-nucleating agent, β-nucleating agent, petroleum resin and synergistic opening agent is 0.005:0.005:1:0.5.

[0068] Wherein, based on the total weight of the compounding aid composition, the content of the antioxidant is 10% by weight, the content of the stabilizer is 10% by weight, and the content of the adhesio...

Abstract

The invention relates to the technical field of polyolefin film processing, and discloses a mixed additive composition, synthetic resin and a polyolefin film / sheet. The mixed additive composition comprises one or more of an antioxidant, a stabilizer and an adhesion enhancer, and the adhesion enhancer is selected from one or more of an alpha nucleating agent, a beta nucleating agent, an optional elastomer, petroleum resin and a synergistic anti-blocking agent; on the basis of the total weight of the blending auxiliary agent composition, the content of the antioxidant is 0.005-10 wt%, the content of the stabilizer is 0.005-10 wt%, and the content of the adhesion enhancer is 80-99.99 wt%. The polyolefin film / sheet has good adhesive force.

Description

technical field [0001] The invention relates to the technical field of polyolefin film processing, in particular to a compounding aid composition, synthetic resin and polyolefin film / sheet. Background technique [0002] Materials are the material basis of human production. Polymer materials are widely used in the packaging industry to prevent the penetration of oxygen, water vapor, and carbon dioxide to keep food, fruits, and vegetables fresh. The growth rate of film production and consumption has been increasing in recent years. With the improvement of people's living standards and the diversification of aesthetics, consumers and producers are pursuing the ultimate in packaging quality and visual effects. [0003] For food preservation, fragrance preservation, and safety considerations, the functional requirements for packaging materials such as puncture resistance and barrier properties are getting higher and higher. It is hoped that external tastes and substances will no...
