Problems solved by technology

[0003] However, the current preparation process of flame-retardant artificial leather is complex and costly, and a large amount of flame retardant is required to achieve the flame-retardant effect, and the use of large doses of flame-retardant artificial leather will cause uneven quality and reduced strength of the prepared flame-retardant artificial leather, which is obviously not possible. Meet people's various needs

Abstract

The invention discloses a preparation method of artificial leather with high flame retardance and high waterproofness. The preparation method comprises the following steps: 1, preparing a flame-retardant resin surface layer; 2, preparing a flame-retardant base cloth; and 3, carrying out calendering lamination and embossing on the flame-retardant resin surface layer obtained in step 1 and the preheated flame-retardant base cloth, carrying out flame-retardant treatment on one surface, back on to the flame-retardant resin surface layer, of the flame-retardant base cloth, and cooling to obtain therequired artificial leather, wherein the step 1 and step 2 are not ordered. The preparation method of the artificial leather with high flame retardance and high waterproofness firstly makes the resinsurface layer and the base cloth subjected to flame-retardant design, and flame retardant treatment is carried out through blade coating and / or coating and / or impregnation of a polyurethane solutioncontaining 4-10% the flame retardance is triple guaranteed, so a good flame-retardant effect can be achieved with a small dosage, the product quality and performances of the artificial leather are excellent, the waterproofness and aging resistance are good, the process is simple, energy is saved, the cost is reduced, and the artificial leather is more suitable for promotion and application.

Description

technical field [0001] The invention belongs to the technical field of artificial leather preparation, and in particular relates to a preparation method of highly flame-resistant and highly waterproof artificial leather. Background technique [0002] Leather is something that people often come into contact with in daily life. In a broad sense, leather includes natural leather and artificial leather. Because artificial leather is cheaper than natural leather and can be mass-produced, it has a wide range of applications in the fields of automobiles and home decoration. application. With the continuous development of economic society and artificial leather technology, people have put forward higher requirements for the performance and quality of artificial leather, especially in terms of flame retardancy, waterproof, anti-aging and other properties. [0003] However, the current preparation process of flame-retardant artificial leather is complex and costly, and a large amount...
