Problems solved by technology

[0003] Although there are many types of silicone-modified silicone rubber, and the addition-type liquid silicone rubber for fabric coating and screen printing has a wide range of options, however, the existing addition-type liquid silicone rubber for fabric coating and screen printing After the silicone rubber is leveled and cured on the textile, the surface is bright. For some products with matte requirements, it is necessary to develop and produce silicone rubber with a matte surface after curing.

Abstract

The invention provides a silica gel used for loomage coating and silk screen printing, which includes the components of the following weight proportion: elements gum 92-98 shares and dummy honour additive 2-5 shares. The elements gum includes polysiloxane linear body 70-80 shares, strengthening filling agent 20-30 shares, and additive 1-5 shares, the additive includes bridging agent 0.1-0.3 shares, cross linker 1-5 shares and inhibitor 0.02-0.05 shares. The surface of the aforementioned silica gel takes dummy honour effect after flatted and cured on the loomage, which makes the characters or patterns on the silica gel clear to be distinguished, and is propitious for user to identify the appellation and brand of the grubstake from long distance. The invention still provides a method for preparing the aforementioned silica gel, which concretely includes the following steps: 1) preparing elements gum, 2) preparing dummy honour additive, 3) preparing the dummy honour silica gel used for loomage coating and silk screen printing. The aforementioned preparing method can be used into the existing industrial raw materials and implements high yield of the final products with simple operation steps and large-scale producing.

Description

technical field [0001] The invention belongs to the field of materials, in particular to a matte silica gel used for fabric coating and silk screen printing and a preparation method thereof. Background technique [0002] The development of organosilicon modification technology for existing rubber is changing with each passing day, and various organosilicon modified rubbers emerge in endlessly. For example, in the research of organosilicon modified polyurethane, the modification method can be copolymerization modification or blending modification. The organosilicon modifier mainly includes silane (such as KH-550, KH-560) or polysiloxane ( Such as hydroxy silicone oil, amino silicone oil), modified products are mainly used as adhesives, coatings, epoxy resin tougheners, fabric coating agents; fluoroalkyl modified silicone oils and their emulsions with waterproof and oil-proof functions are mainly used as fabrics Finishing agent and lubricating oil; a series of water-based flu...
