Low-density heat insulation type foam material and processing process thereof

Abstract

The invention discloses a low-density heat insulation type foam material. The material is composed of a component A and a component B, wherein the component A and the component B are mixed according to a mass ratio of 1: 1; and the mixture is cured at 15-40 DEG C to generate a foaming body. According to a processing process of the foam material, all the raw materials are weighed according to the composition formula of the component A and the component B and added into an inner sleeve box in a mixing disc of a multifunctional dispersing and mixing machine; a plurality of second conical scrapingstrips are obliquely arranged on the two sides of a rotary plate, all the raw materials are scraped and stirred through the second conical scraping strips, and the dispersing and mixing efficiency ofall the raw materials is improved. A first hydraulic pump continuously drives the mixing disc to reciprocate up and down through a first hydraulic rod, so that the raw materials are dispersed and mutually mixed more comprehensively and efficiently, the foam raw materials are foamed and prepared with higher quality and more uniform and lower density; and the multifunctional dispersing and mixing machine is time-saving and labor-saving in use and high in working automation degree, and shortens the time period required by the processing technology.

Description

technical field [0001] The invention belongs to the technical field of foam materials, and in particular relates to a low-density heat-insulating foam material and its processing technology. Background technique [0002] Foam plastic is a kind of polymer material formed by a large number of gas micropores dispersed in solid plastic. It has the characteristics of light weight, heat insulation, sound absorption, shock absorption, etc., and has a wide range of uses. [0003] There are still many deficiencies in the existing foam materials when they are processed. When the existing foam materials are processed, the raw materials required for the foam materials are dispersed and mixed not uniformly and comprehensively. The mixing reaction is not complete enough, resulting in the poor quality of the foam material after production, the density of the produced foam is uneven and thick, and the efficiency of foam processing is slow, and the processing time is very long, which is extr...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that when the existing foam materials are processed, the dispersion and mixing of the raw materials required by the foam materials are not uniform and comprehensive enough, and the mixing reaction between the raw materials of the foam is not complete enough, resulting in the foam materials being produced. The quality of the finished product is very poor, the density of the produced foam is uneven, the density is thick, and the efficiency of the foam is slow when it is processed, and the time period spent in processing is very long, which greatly increases the time required for the foam material to be processed. cost, and when the foam material is being processed, it is not convenient for the staff to add each raw material to the multifunctional dispersing mixer, and when adding materials, the raw materials are not uniformly and comprehensively dispersed in the multifunctional dispersing mixer, which seriously reduces the cost of each raw material. The problem of mixed reaction efficiency and quality between, and provide a kind of low-density thermal insulation foam material and its processing technology
