Problems solved by technology

[0003] However, the traditional pillow stuffing has the following defects: cotton is difficult to clean, especially when used for a long time, it will be soaked in sweat and it is difficult to remove; synthetic fibers are difficult to support the head firmly, causing pain and fatigue in the head and shoulders; Use seed husks or buckwheat husks, which can breed mold, bacteria, etc.
But this application technology has the following defects: 1. The polymer toughening auxiliary material adopted is aromatic, and the consumption is 50%-70% of the polypropylene base material, which is not suitable for filling of pillows that people use every day 2. It uses coal slag and industrial waste as raw materials, and the dosage is 70%-100% of the polypropylene base material. Obviously, this is conducive to making full use of resources, but such raw materials with unknown components are not suitable for use on pillows.

preparation example Construction

[0031] The preparation method of the above-mentioned PP composite foam material provided in this embodiment includes the following steps:

[0032] Step 1: After mixing PP, PE and processing aids, kneading is performed once to obtain the raw material; the temperature of the first kneading is 120-150° C., and the time is 2-5 minutes.

[0033] Step 2, preparing modified bamboo pulp fibers; the operation includes crushing bamboo pulp fibers, melting natural rosin resin, adding an initiator, mixing the three fully, and reacting at 150-200°C for 2-5 hours to obtain modified bamboo pulp fibers pulp fibers. The weight ratio of the bamboo pulp fiber to the natural rosin resin is 1:(1-4); the initiator adopts cyclohexanone peroxide, and its added amount is calculated by weight percentage, which is 0.5-10% of the weight of the bamboo pulp fiber.

[0034] Step 3, performing secondary kneading and extrusion molding on the primary material and the modified bamboo pulp fiber to obtain a PP ...

Embodiment 1

[0037] The parts by weight of the components of the PP composite foam material provided in this example are: 100 parts of PP and PE in total, 30 parts of reinforcing and toughening auxiliary materials; 3 parts of foaming agent, 2 parts of dispersing agent, 6 parts of flame retardant, 2 parts of oxygen agent; 2 parts of anti-aging agent; wherein the weight ratio of PP and PE is 1:1.

[0038] The preparation method of the above-mentioned PP composite foam material provided in this embodiment comprises the following steps:

[0039] Step 1: After mixing PP, PE and processing aids, kneading is performed once to obtain the raw material; the temperature of the first kneading is 130° C., and the time is 3 minutes.

[0040] Step 2, preparing modified bamboo pulp fibers; the operation includes crushing bamboo pulp fibers, melting natural rosin resin, adding an initiator, mixing the three fully, and reacting at 160-180°C for 4 hours to obtain modified bamboo pulp fibers . The weight ra...

Embodiment 2

[0043] The difference between this embodiment and embodiment 1 is that the weight ratio of bamboo pulp fiber and natural rosin resin is 1:2.

Abstract

The invention belongs to the technical field of high polymer composite materials and in particular relates to a PP composite foam material as well as a preparation method and application thereof. ThePP composite foam material contains PP, PE, reinforced and toughened auxiliary materials and processing aids, wherein the reinforced and toughened auxiliary materials adopt modified bamboo pulp fibers. The preparation method comprises the following steps: performing primary kneading, preparing modified bamboo pulp fibers, performing secondary kneading and performing extrusion molding. The PP composite material mainly adopts raw materials beneficial to the human body, so that the toughness and strength are improved.

Description

technical field [0001] The invention belongs to the technical field of polymer composite materials, and in particular relates to a PP composite foam material and its preparation method and application. Background technique [0002] A pillow is a type of bedding used to support the head comfortably while sleeping, generally made of a pillow case and pillow stuffing. Pillowcases are usually made of a cotton-like fabric, and the inside of the pillowcase is stuffed with pillow stuffing to maintain a certain volume. Traditional pillow fillings mostly use cotton, polyester synthetic fibers, feathers, sponges, husks obtained from adzuki beans and chestnuts, chaff or buckwheat husks, etc. [0003] However, the traditional pillow stuffing has the following defects: cotton is difficult to clean, especially when used for a long time, it will be soaked in sweat and it is difficult to remove; synthetic fibers are difficult to support the head firmly, causing pain and fatigue in the head...
