Problems solved by technology

[0003] The existing fastener technology has the following problems: the material of the fastener is mostly steel, and the steel itself is a kind of building material that will not burn. It has the characteristics of earthquake resistance and bending resistance, and its good characteristics make it widely used However, in the actual use process, when the steel encounters high temperature, its mechanical properties, such as yield point, tensile strength and elastic modulus, will drop sharply due to the increase of temperature, so that the firmness between the firmware The performance is significantly lower, and there is a great potential safety hazard

preparation example Construction

[0015] A preparation method for a flame retardant coating for a fastener, comprising the steps of:

[0016] (1) Mix the polyvinyl chloride, water-based epoxy resin, and phenyl salicylate in the stated parts by mass, and disperse them at high speed with ultrasonic waves. About 40~60min;

[0017] (2) Add the polyethylene wax emulsion, styrene-acrylic emulsion, natamycin, and tetrabutyl titanate in the stated mass parts, and disperse at a high speed by ultrasonic. The ultrasonic frequency is 20-35KHz, and the dispersion speed is about 4800-5200r / min , the dispersion time is about 30-50 minutes;

[0018] (3) Add the PVC resin, tricresyl phosphate, aluminum hydroxide powder, and polyhexamethylene biguanide hydrochloride in the stated mass parts, and disperse at high speed by ultrasonic, with an ultrasonic frequency of 20-30KHz and a dispersion speed of about 4600- 4800r / min, the dispersion time is about 20-40min; the product is obtained after mixing evenly.

Abstract

The invention discloses a flame-retardant coating for a fastener and a preparation method of the flame-retardant coating. The wear-resistant coating is prepared from the following raw materials in parts by weight: 24-30 parts of PVC, 20-22 parts of water-borne epoxy resin, 18-22 parts of polyethylene wax emulsion, 12-16 parts of styrene-acrylic emulsion, 12-16 parts of PVC resin, 18-22 parts of tricresyl phosphate, 14-18 parts of aluminum hydroxide powder, 12-16 parts of polyhexamethylene biguanidine hydrochloride, 14 to 18 parts of natamycin and 14 to 18 parts of tetrabutyl titanate. The invention provides the flame-retardant coating for the fastener, the flame-retardant coating coats the surface of the fastener, so that the fastener has a certain flame-retardant property, and the mechanical property of the fastener is guaranteed.

Description

technical field [0001] The invention relates to a coating, in particular to a flame-retardant coating for fasteners and a preparation method thereof. Background technique [0002] Fasteners are the foundation of the development of the industrial industry, which directly affects the quality and safety of the overall mechanical products. However, fasteners will encounter some problems during use, such as loosening, rusting, seizure, and even fracture. The occurrence of these phenomena has major safety hazards or even serious accidents. For this reason, strict quality control of fasteners, correct installation, maintenance, inspection, and research and development of high-performance protective coatings are all very important, and have been highly valued by people. [0003] The existing fastener technology has the following problems: the material of the fastener is mostly steel, and the steel itself is a kind of building material that will not burn. It has the characteristics ...
