Problems solved by technology

Nylon monofilament mesh is required to be both beautiful and durable, but the actual situation is that the product is often prone to creep and warpage. The reasons are: 1. Since nylon is a high-crystalline material, it is particularly easy to generate internal stress when making products, especially The most important thing is that when the product structure is relatively complex, this internal stress will be gradually released in the later process, resulting in warping of the product; 2. Nylon is a high water-absorbing material, because it must be dried before injecting the product, so that the product is After the production is completed, it will inevitably absorb water again. After absorbing water, the physical and mechanical properties of the nylon material will change significantly, which is the creep property of the product.

Abstract

The invention relates to a nylon monofilament mesh flexible agent which comprises the following components in parts by weight: 3-20 parts of polyurethane, 0.5-5 parts of an alkali compound, 10-100 parts of a pure acrylic emulsion, 2-10 parts of zinc salt, 30-70 parts of an illegal cooking oil treatment liquid, 5-20 parts of rosin, 0-8 parts of white mineral oil, 2-20 parts of turpentine and 2-5 parts of an emulsifier. The nylon monofilament mesh flexible agent is prepared from the illegal cooking oil treatment liquid as a main raw material, the preparation method is convenient and rapid, afterthe preparation method is applied to a nylon monofilament mesh, the operation is simple, and the treatment effect is good, and after treatment, the tensile strength and the impact resistance of the nylon monofilament mesh are increased by 10-15%, and the product can be flexible and solid.

Description

technical field [0001] The invention relates to a flexible agent, in particular to a nylon single mesh flexible agent and its preparation and application method. Background technique [0002] Nylon monofilament mesh is a monofilament mesh made of polyamide resin as the base material. It has excellent strength, toughness, oil resistance and wear resistance. It can be used as fishing line, brush, screen wire, toothbrush, musical instrument string, Surgical sutures, etc. Nylon monofilament mesh is required to be both beautiful and durable, but the actual situation is that the product is often prone to creep and warpage. The reasons are: 1. Since nylon is a high-crystalline material, it is particularly easy to generate internal stress when making products, especially The most important thing is that when the product structure is relatively complex, this internal stress will be gradually released in the later process, resulting in warping of the product; 2. Nylon is a high water...
