Composition containing sodalite and polyester composite

Abstract

The invention provides a composition containing sodalite. The composition comprises 55 to 98.5 wt% of dihydric alcohol, polybasic carboxylic acid and 0.5 to 20 wt% of sodalite particles with an average particle size of 10 to 300 nm, wherein a weight ratio of the sodalite particles to polybasic carboxylic acid is in a range of 0.2-3: 1. The invention also provides a polyester composite. A precursor of the polyester composite comprises the composition containing sodalite, precursor dihydric alcohol and precursor dicarboxylic acid, wherein the sum of the mole number of the precursor dihydric alcohol and the mole number of the dihydric alcohol in the composition containing sodalite is a first mole number, the sum of the mole number of the precursor dicarboxylic acid and the mole number of the polybasic carboxylic acid in the composition containing sodalite is a second mole number, a ratio of the first mole number to the second mole number is in a range of 1-1.5: 1, and the sodalite particles accounts for 0.01 to 1 wt% in the polyester composite. The sizes of the sodalite particles are nanometer or almost nanometer, and the sodalite particles can be uniformly dispersed in the dihydric alcohol.

Description

technical field [0001] The invention relates to a polyester composite material with far-infrared radiation and anti-ultraviolet functions and a composition containing sodalite as its precursor. Background technique [0002] The wavelength of far-infrared rays is between 4-14 microns. Because of its penetrating ability and resonance absorption phenomenon, it can make the molecules of the subcutaneous tissue vibrate and convert the energy into heat energy, which can increase the temperature of the subcutaneous tissue, expand microvessels and promote blood circulation. Therefore, far-infrared rays are also called fertility rays. [0003] In recent years, people have tried to add far-infrared material powders such as metals, oxides, ores and carbonized plants with far-infrared radiation capabilities to polyester materials to endow polyester materials with higher far-infrared emissivity and derive Subsequent multiple applications. [0004] In the past, in order to add far-infra...

Problems solved by technology

[0007] However, the above-mentioned technology has its disadvantages in that the process of grinding far-infrared materials to micron or nanometer size is a time-consuming and energy-consuming process, which usually takes tens of hours to several days; Processing, high-temperature calcination and other technologies to shorten the grinding time or produce smaller, more uniform powder, but these additional processing processes require additional energy input

In addition, due to the high hardness of most far-infrared materials, the problem of grinding equipment wear is serious, and the depreciation and replacement rate is high

[0008] In addition, another disadvantage of the aforementioned technology is that in order to allow the ceramic powder to be uniformly dispersed in the solution and polyester materials, additional dispersants are required, and the addition of dispersants will not only affect the mechanical properties of the final product, It is also easy to affect the stability of the polyester material manufacturing process
