Embodiment 1

[0031] A pump body of a canned pump, the pump body is made by mixing the following components by weight: 57%-62% of nylon six; 32%-35% of glass fiber; 5%-7% of compatibilizer; Agent 0.3%-0.4%; filler: 5%-10%; flame retardant 15%-20%;

[0032] The diameter of the glass fiber is between 21-35μm, and the length is between 0.1-5mm, and the compatibilizer is POE-g-MAH (ST-2) or EPDM-g-MAH (ST-18) or PE- g-MAH (ST-6); wherein the antioxidant is antioxidant 618 or antioxidant 6101 or antioxidant 601; wherein the filler adopts inert materials such as active calcium carbonate or talcum powder or wollastonite or mica; wherein The flame retardant uses a halogen-containing flame retardant or a halogen-free flame retardant. In order to meet environmental protection requirements, the present invention uses a halogen-free flame retardant, such as a white powdery phosphine-nitrogen flame retardant.

[0033] As a preferred solution, a pump body of a canned pump, the pump body is made by mixin...

Embodiment 2

[0040] The manufacturing method and formula components of this embodiment and embodiment 1 are basically the same, the only difference is that the pump body material formula of the canned pump is as follows: nylon six 57%; glass fiber 32%; compatibilizer 5%; antioxidant 0.3 %; filler 5%; flame retardant 15%, wherein the compatibilizer is EPDM-g-MAH (ST-18);

Embodiment 3

[0042] The manufacturing method and formula components of this embodiment and Example 1 are basically the same, the only difference is that the pump body material formula of the canned pump is as follows: nylon six 62%; glass fiber 35%; compatibilizer 6%; antioxidant 0.4 %; filler 8%; flame retardant 18%, wherein the compatibilizer is PE-g-MAH (ST-6).

[0043] The performance comparison of the foregoing embodiments is as follows:

Abstract

The invention discloses a shield pump body and a processing method thereof, and aims to provide a shield pump body with light weight, high mechanical strength, simple processing technology and strongpracticability. The shield pump body is technically characterized by mixing the following components in percentage by weight: 50%-70% of nylon 6, 30%-40% of glass fiber, 3%-8% of a compatibilizer, and0.2%-0.5% of an antioxidant. The shield pump body is applicable to the technical field of shield pumps.

Description

technical field [0001] The invention relates to the technical field of canned pumps, more specifically, to a canned pump body and a processing method thereof. Background technique [0002] Traditional canned pumps are used to transport materials, and the pump body of the traditional canned pump is usually made of aluminum alloy die-casting or cast iron shell, but such a pump body is not only heavy, but also has a complicated production process, high production cost, low practicability, and Not easy to promote. [0003] Therefore, according to the above-mentioned problems of the pump body, a canned pump body with light weight, high mechanical strength, simple processing technology and strong practicability is required. Contents of the invention [0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a canned pump body with light weight, high mechanical strength, simple processing technology and strong practicability. [00...
