Problems solved by technology

In addition to the special properties required for this type of coating material, due to the long-term use of the material outdoors, the use environment is relatively harsh, and it has to withstand the attack of ultraviolet rays and various atmospheric pollutants for a long time, which accelerates the degradation of PVC on the one hand, and on the other hand Due to the migration of plasticizers in PVC, the surface of the coating is sticky, making the product easy to stick to dust
Cracking, premature product failure

Embodiment 1

[0031] The specific steps are:

[0032] 1) Sending: The polyester fiber grey cloth (high-strength polyester fiber grey cloth) is placed on the sending device for sending, and one end of the core tube on the sending device is equipped with a magnetic braking device to adjust the tension;

[0033] 2) Preheating and ironing: Preheat and iron the grey fabric on the sending device through the preheating ironing device; this step is a set of heating steel rollers, and the temperature is controlled at 80 degrees to ensure the moisture in the fabric and the low molecular weight contained in the fabric. Volatiles are excluded here to prevent pinholes from affecting air tightness due to volatilization and escape in subsequent coatings;

[0034] 3) Double-sided coating treatment: use a coating machine for padding and vertical scraping, and immerse the preheated and ironed grey cloth into the paste to make the warp and weft of the cloth full of paste, and then pass through a pair of rolle...

Embodiment 2

[0050] The specific steps are:

[0051] 1) Sending: The polyester fiber grey cloth (high-strength polyester fiber grey cloth) is placed on the sending device for sending, and one end of the core tube on the sending device is equipped with a magnetic braking device to adjust the tension;

[0052] 2) Preheating and ironing: preheat and iron the grey fabric on the sending device through the preheating ironing device; this step is a set of heating steel rollers, and the temperature is controlled at 120 degrees to ensure the moisture in the fabric and the low molecular weight contained in the fabric. Volatiles are excluded here to prevent pinholes from affecting air tightness due to volatilization and escape in subsequent coatings;

[0053] 3) Double-sided coating treatment: use a coating machine for padding and vertical scraping, and immerse the preheated and ironed grey cloth into the paste to make the warp and weft of the cloth full of paste, and then pass through a pair of roll...

Embodiment 3

[0070] The specific steps are:

[0071] 1) Sending: The polyester fiber grey cloth (high-strength polyester fiber grey cloth) is placed on the sending device for sending, and one end of the core tube on the sending device is equipped with a magnetic braking device to adjust the tension;

[0072] 2) Preheating and ironing: the grey fabric is preheated and ironed on the sending device through the preheating ironing device; this step is a set of heating steel rollers, and the temperature is controlled at 100 degrees to ensure the moisture in the fabric and the low molecular weight contained in it. Volatiles are excluded here to prevent pinholes from affecting air tightness due to volatilization and escape in subsequent coatings;

[0073] 3) Double-sided coating treatment: use a coating machine for padding and vertical scraping, and immerse the preheated and ironed grey cloth into the paste to make the warp and weft of the cloth full of paste, and then pass through a pair of rolle...

Abstract

The invention provides a process for producing a door curtain material, which comprises delivery of polyester fiber grey cloth, double-face coating treatment, pre-plasticizing and gelling, planishing and cooling, primary coating of a horizontal coating head, plasticizing treatment, cooling and shaping, secondary coating of the horizontal coating head, plasticizing treatment, embossing, cooling, winding, surface treatment and preparation. The process combines net sandwich cloth coating and surface treatment process, is complete relatively to common coating processing, can process a vertical coating, a surface layer and a bottom layer, reduces the intrusion of ultraviolet rays on the coating by adopting the surface treatment process on the one hand, can prevent plasticizing agent from being transferred to the surface of a product on the other hand so as to achieve the antifouling effect and achieve the aim of self-cleaning by means of rainwater; and the product has good air tightness and superior abrasion-resisting property, is suitable for outdoor application, and has long service life and remarkable economic benefit.

Description

technical field [0001] The invention belongs to the field of chemical industry, and more particularly relates to a production process of door curtain material. Background technique [0002] PVC door curtain material production, widely used in electronic factories and warehouse shopping malls for fast rolling doors, anti-static mesh curtains, fire-retardant and flame-retardant door curtains and cargo partitions, with strong sealing, no dust accumulation, high stability, and easy cleaning. The advantages are that it can realize the high-speed opening and closing of the factory door, improve the logistics speed, and prevent the flying of flying insects and the influx of pollutants such as dust. Effectively block the loss of air conditioning and heating. In addition to the special properties required for this type of coating material, due to the long-term use of the material outdoors, the use environment is relatively harsh, and it has to withstand the invasion of ultraviolet r...
