Embodiment 1

[0017] Embodiment one, the coating of polyester plain spinning class umbrella cloth

[0018] After dissolving 22% (weight ratio, the same below) of the illusion powder with toluene, add 58% of PA glue (polyacrylate) and stir evenly; then add 2% of diisocyanate, 1% of chlorinated paraffin and Toluene solvent, and make the total amount of solvent be controlled at 17%. Stir evenly to form spare glue X1; repeat the above steps to prepare spare glue X2.

[0019] Place the gray cloth coated with PA glue on the machine table, adjust the scraper to an appropriate height, and then apply the coating glue X1 on the gray cloth, control the temperature between 120-130°C, and apply the coating glue X2 after drying Coat the upper fabric, control the temperature at 135-145°C, and control the speed at 45-55m / min.

[0020] The coated fabric was tested with the HB902 anti-ultraviolet penetration and sun protection tester according to the national standard GB / T18830. The measured results are: t...

Embodiment 2

[0023] Repeat embodiment one, and each component is prepared by following weight ratio:

[0024] Symphony powder 25%, PA glue 55%, diisocyanate 3%, chlorinated paraffin 1.2%, solvent 15.8%.

Embodiment 3

[0026] Repeat embodiment one, and each component is prepared by following weight ratio:

[0027] Symphony powder 20%, PA glue 60%, diisocyanate 1%, chlorinated paraffin 0.5%, solvent 18.5%.

Abstract

The invention discloses a magic powder type umbrella lining coating and coating method, which comprises the following steps: dissolving 20-25% (mass ratio) magic powder with dissolvent; adding 55-60% PA liquid cement; stirring evenly; adding into 1-3% cross linker, 0. 5-1. 5% antisticking agent and dissolvent; controlling total quantity of the dissolvent at 14-20%; stirring evenly; forming spare glue X1; repeating the step; preparing glue X2; coating PA glue on the grey cloth; placing on machine bench; adjusting adze scraper to proper height; coating the X1 on the grey cloth; controlling the temperature between 120 deg. c and 130 deg. c; drying; coating the X2 on the face fabric; controlling the temperature at 135-145 deg. c; controlling the car speed at 40-55m/min; This invention possesses good effect of ultraviolet resistance.

Description

technical field [0001] The invention relates to a coating for an umbrella fabric and a coating method thereof, in particular to a scraper coating process, in particular to a magic powder umbrella fabric coating and a coating method. Background technique [0002] The existing umbrella surface coating usually adopts a relatively popular doctor blade coating process. In order to improve the aesthetics of the umbrella surface, a high-refractive-index magic powder additive is used during coating. Symphony powder is refined from natural mica minerals. Specifically, mica powder is used as the core base material, and the outer layer is coated with nano-metal oxides. It is made by high-temperature calcination. It can show this illusion effect in the refraction of light. The product itself does not spontaneously ignite and is non-conductive. , Non-toxic, non-irritating, high temperature resistance, strong weather resistance. The cloth surface coated with this magic powder coating is...
