Embodiment 1

[0034] Comparing Example 1 with Comparative Example 1, the amount of plasticizer used is lower than the normal range, the elongation at break of the material is lower than the required value, and the low-temperature impact embrittlement temperature also fails to meet the requirement. The amount of stabilizer is lower than the normal range, and the thermal stability time of the material at 200°C is lower than the required value.

[0035] Comparing Example 1 with Comparative Example 2, the amount of plasticizer used is higher than the normal range value, the tensile strength of the material is lower than the required value, and the oxygen index of the material is also lower than the required value.

[0036] Comparing Example 1 with Comparative Example 3, the dosage of the toughening agent is lower than the normal range value, and the low temperature resistance of the material cannot meet the requirements.

Embodiment 2

[0037] Compared with Comparative Example 4, the amount of calcium carbonate in Example 2 exceeds the normal range, and the low temperature resistance of the material does not meet the requirements.

Embodiment 3

[0038] Compared with Example 5, the amount of flame retardant used in Example 3 is lower than the normal range, and the oxygen index of the material is lower than the required value.

[0039] like figure 1 Shown, the product of embodiment 1 coextrudes the sectional view (extrusion temperature 145-155 ℃) in 65+45 machine, figure 1 It can be seen that the product is a double-layer extrusion process, which has high requirements for the fusion of material joints. At the same time, the fluidity of the product is required to ensure the consistency of the product size.

[0040] The PVC zipper sleeve made from the composition of Example 1 was subjected to a performance test, and the results are shown in Table 3.

Abstract

The invention provides a matte flame-retardant PVC composition as well as a preparation method and application thereof. The composition comprises the following raw materials in parts by weight: 100 parts of polyvinyl chloride resin, 40-50 parts of a plasticizer, 5-8 parts of a stabilizer, 15-25 parts of calcium carbonate, 0.3-0.5 part of a lubricant, 6-10 parts of a flame retardant, 2-5 parts of extinction powder and 5-8 parts of a toughening agent. The invention also provides a preparation method of the composition. The composition can be used as an automobile wire harness zipper sleeve, operation and wire installation are convenient, cost is low, the interior of the sleeve is smooth, and wires can be well protected.

Description

technical field [0001] The invention relates to a PVC material, in particular to a matt flame-retardant PVC composition for a zipper sleeve of an automobile wiring harness and a preparation method thereof, belonging to the technical field of PVC materials. Background technique [0002] The rapid development of the automobile industry has become an indispensable pillar of the national economy. After more than 100 years of development and evolution, it has now entered the mature stage of the industry. The annual growth rate of car ownership is stable. The car wiring harness is the main body of the car circuit network. Without the wiring harness, there will be no car circuit. The wire harness refers to the contact terminal (connector) punched from copper and the wire and cable after crimping, and then plastic insulator or metal shell on the outside, and then bundled with wire harness to form a connected circuit component. The wire harness industry chain includes wire and cabl...
