Problems solved by technology

But thermoplastic polyurethane (TPU) also has disadvantages at the same time, its light aging resistance and heat aging resistance, and its flame retardancy is also very poor. These two shortcomings basically limit the application of TPU materials in the field of sun fabrics.

Embodiment 1

[0023] (1) Dry the TPU and anti-adhesive masterbatch at 105°C for 3 hours for later use.

[0024] (2) According to the formula in Table 1, physically blend TPU with various fillers, mix well and set aside.

[0025] (3) The mixed TPU particles are melted in the extruder and coated with PET precursors to obtain coated yarns, and the yarns are woven and shaped into finished fabrics. Among them, the parameters of the extruder are set as follows: the temperature of the die head and the screw is set to 210°C, the temperature of the barrel outlet is set to 180°C, the screw speed is 50r / min, and the winding speed is set to 400m / min. min. The yarn obtained under this process condition is subjected to warping, weaving, heat setting and other processes to obtain a flame-retardant and halogen-free TPU sunshine fabric; among them, the temperature of heat setting is 160°C, the speed is 15m / min, and the quality of TPU / PET Ratio = 72%: 28%. The obtained TPU fabric was tested for performanc...

Embodiment 2

[0031] Concrete each production process is the same as implementing 1, just formula is different, and formula is as shown in table 3. The obtained TPU fabric was tested for performance, and the results are shown in Table 4.

Abstract

The invention relates to a preparation method of flame-retardant halogen-free TPU sunscreen fabric. The preparation method comprises following steps: drying TPU and anti-sticking particles; physically blending dried TPU and fillers in proportion in order to obtain mixed TPU particles; melting obtained TPU particles via an extruder and coating TPU particles with PET original yarns in order to obtain coated yarns; and obtaining flame-retardant halogen-free TPU sunscreen fabric by warping, weaving and heat setting. The preparation method of flame-retardant halogen-free TPU sunscreen fabric has following beneficial effects: the obtained sunscreen fabric is high in flame retardance and antibacterial property, fine in anti-light aging property and anti-thermal ageing performance and is in accord with the environmental protection concept and has fine application prospect and great research value.

Description

technical field [0001] The invention belongs to the field of preparation of TPU sunshine fabrics, in particular to a preparation method of flame-retardant halogen-free TPU sunshine fabrics. Background technique [0002] Sunshine fabric refers to a kind of fabric that is used to block sunlight and sunlight to play an auxiliary function. It is usually used together with other fabrics to cover items to avoid strong light exposure. The most basic sunshine fabric has the ability to block strong light and The role of ultraviolet rays, and flame-retardant sunlight fabrics mean that the refraction effect basically reaches 85%-99%, and the opening rate ranges from 1%-15%. It has the characteristics of sunshade, light transmission, and ventilation, which can eliminate most of Exposure to sunlight can keep the indoor air unobstructed, and at the same time, sunny fabrics with flame-retardant functions generally have permanent flame-retardant effects. [0003] Thermoplastic polyurethane...
