Problems solved by technology

Moreover, the pace of life is generally relatively fast now, so people hope to get enough relaxation when sleeping, and a wide variety of products have been launched on the market for people with such needs, such as mattresses, pillows and cushions with nursing functions, etc. It also advertises that it has certain medical and sleep-helping effects, so when consumers make choices, they only focus on the specific effects, and do not seriously explore the actual materials used.
[0003] In the prior art, most of the fillers used in mattresses, pillows and cushions sold on the market are made of chemical fiber, pearl cotton or PVC. Poor air permeability, anti-aging, anti-oxidation, and impact resistance are also relatively weak, so it will greatly affect the consumer's perception. After a period of use, it is easy to deform and cannot be used for a long time, especially because chemical fiber itself contains Chemical substances are not green and environmentally friendly, and they are harmful to the body

Embodiment 1

[0032] The raw materials of the composite filling material are as follows:

[0033]

[0034] The preparation method of the composite filling material is as follows:

[0035] 1) Place polyethylene-octene copolymer, ethylene-vinyl acetate copolymer and azodicarbonamide in a container, mix and stir evenly, and then extrude through a single-screw extruder;

[0036] 2) During the extrusion process, add polyhydric reactive flame retardants, plasticizers, and antioxidants, extrude them into molds for vacuum setting, place them at room temperature to cool, and then cut and shape them according to requirements and directly fill them into mattresses use.

Embodiment 2

[0038] The raw materials of the composite filling material are as follows:

[0039]

[0040] The preparation method of the composite filling material is as follows:

[0041] 1) Put polyethylene-octene copolymer, ethylene-vinyl acetate copolymer, azodicarbonamide, and toluenesulfonyl hydrazide in a container, and mix and stir at a stirring rate of 300rad / min and a temperature of 30°C Extrude through a twin-screw extruder after uniformity for 20 minutes. The extrusion temperature is controlled at 150°C, the main engine frequency is 30Hz, and the screw diameter is controlled at 50mm;

[0042] 2) During the extrusion process, add dimethyl methyl phosphate, plasticizer, antioxidant, lubricant, and pH regulator and extrude into the mold for vacuum setting. At this time, the extrusion temperature of the twin-screw extruder is controlled at 140°C, main engine frequency 25Hz, screw diameter controlled at 55mm, then placed at room temperature and cooled to 25°C, cut and shaped accor...

Abstract

The invention provides a composite filling material, a preparing method thereof and an application thereof. The composite filling material mainly comprises, by mass, 40 parts to 70 parts of polyethylene-octylene copolymers, 50 parts to 80 parts of ethylene-vinyl acetate copolymers, 8 parts to 10 parts of foaming agents, 2 parts to 6 parts of fire retardants and 3 parts to 10 parts of processing agents. The preparing method includes the steps that A, the polyethylene-octylene copolymers, the ethylene-vinyl acetate copolymers and the foaming agents are evenly mixed and stirred and extruded through an extruder; B, in the extruding process, the fire retardants and the processing agents are added, then the mixture is extruded into a mold for vacuum shaping, and finally cooling is carried out to obtain the product. The composite filling material serves as fillers in a cushion, a mattress and a pillow to be applied. The composite filling material has the advantages that aging is not prone to occurrence, the air retaining performance is good, the affinity and the soft performance are good, and deformation is not prone to occurrence after long time use.

Description

technical field [0001] The invention relates to the field of polymer material processing, in particular to a composite filling material and its preparation method and application. Background technique [0002] With the progress of the times, people have higher pursuits for various daily necessities.
