Problems solved by technology
[0003] The present invention provides an application of bright white aluminum-silver paste on the umbrella cloth, which mainly solves the problem in the prior art that aluminum-silver is prone to occur due to the poor fastness of floating silver ZF2512 when producing dark colors such as big black. Technical problems such as slurry anti-staining color surface, etc.

Embodiment
[0023] Embodiment: the application of a kind of bright white aluminum silver paste on the umbrella cloth of this example is characterized in that described application method comprises:
[0024] a. Melt aluminum ingots with an aluminum content > 99.5%, then atomize and sieve them into aluminum powder, then add mineral oil and lubricant to the aluminum powder, the mass ratio of mineral oil to aluminum powder is 0.6:1, The mass ratio of lubricant to aluminum powder is 1.2:1, and the mixture is put into a ball mill for ball milling twice, such as figure 1 , the inner wall of the housing 1 of the ball mill is provided with a plurality of telescopic extruding blocks 2, and the inner end of the extruding block is provided with an elastic member 3. The first ball mill is to use mixed large steel with a diameter of 4-5mm. After the ball is extruded for 1 hour, it adopts the method of gradually heating up. The heating rate is 1°C / min, rising to 40°C. After the first ball milling is com...

The invention relates to umbrella fabric, in particular to the application of bright and white aluminum paste on the umbrella fabric. The application mainly solves the technical problems that aluminum paste is easy to stain a color plane due to the poor fastness of floating aluminum ZF2512 when dark color umbrella fabric, such as black umbrella fabric are produced in the prior art. The application comprises the steps of performing melting, atomizing, primary sieving, twice ball milling, secondary sieving, filter pressing and mixing on an aluminum ingot so as to finally obtain aluminum paste SFK-10; performing waterproof treatment on the umbrella fabric, so as to form a waterproof layer, performing light calendering finish, compounding DL-216X glue, the aluminum paste SFK-10, aluminum paste ZNA111, a bridging agent NL-750, a slip agent and trimethyl benzene into a coating layer, and then coating the waterproof layer of the umbrella fabric with the coating layer; performing baking, and finally obtaining the umbrella fabric coated with the bright and white aluminum paste after three times of slow heating and three times of flash cooling.
Description
technical field [0001] The invention relates to an umbrella cloth, in particular to the application of bright white aluminum-silver paste on the umbrella cloth. Background technique [0002] Silver tape is one of the largest varieties of umbrella cloth. The aluminum silver paste of silver tape is coated on the surface of the umbrella cloth, which is not only beautiful, but also can greatly improve the anti-ultraviolet effect of the umbrella. The commonly used aluminum silver pastes are bright silver ZF1010 (high brightness, high price and poor covering effect), immersion silver ZNA111 (good covering effect and fastness, insufficient bright whiteness), floating silver ZF2512 (high whiteness, but poor fastness ). In actual production, three kinds of aluminum and silver pastes are generally used in combination, but when producing dark colors such as big black, because of the poor fastness of ZF2512, it is easy to cause the aluminum and silver paste to stain the color surface. ...
