Embodiment 1

[0040] Shrinkage-resistant finishing was accomplished by immersing a mesh fabric B consisting of polyester fibers and having pores D with a maximum length of 5 mm in a pretreatment solution containing 95 g of 5 g aminosilane in water.

[0041] Subsequently, a liquid silicone rubber composition comprising 94% by weight of an addition-type liquid silicone rubber having a viscosity of 3,000 centipoise was applied to the preshrunk-treated mesh fabric B by intermittent knife coating. , 5.0% by weight of pigment, 0.5% by weight of fused silica and 0.5% by weight of methylvinyl hydrogen polysiloxane; subsequently, before the liquid silicone rubber composition is dried, the liquid silicone rubber coated with The mesh fabric of the composition is subjected to hot air injection. Finally, the dried product was dried at 80° C. for 3 minutes and then at 200° C. for 4 minutes, thereby preparing a coated web.

[0042] Physical property evaluations were performed on the coated webs and the ...

Abstract

The invention discloses a method for preparing mesh coated with liquid silicon rubber. The method comprises the following steps: (i) mesh fabrics, in which holes are formed, are subjected to shrink-resistant treatment; (ii) liquid silicon rubber composition, of which the viscosity is 300-500,000 centipoises, is coated on the shrink-resistant treated mesh fabrics; and (iii) before the liquid silicon rubber composition is dried, air is injected to the mesh fabrics coated with the liquid silicon rubber composition. With excellent releasing property, the disclosed mesh coated with the liquid silicon rubber is used as linings of steamed dishes; and with excellent anti-skid property, the mesh can be used for manufacturing each kind of anti-slid mat using the coated mesh.

Description

technical field [0001] The present invention relates to a mesh coated with liquid silicone rubber (hereinafter, generally referred to as 'coated mesh'), and more particularly, to a method for preparing a coated mesh by coating liquid silicone rubber. A method for a coated web having improved release properties and non-slip properties sufficient to use it as a liner for steamed dishes or other various non-slip mats. Background technique [0002] Generally, most mats for steaming dished foods such as Korean dumplings or rice cakes are made of cotton fabric. However, such cotton fabrics have poor release properties (for food). Since the food is not well separated from the cotton fabric, the original shape of the food is easily collapsed or deformed, and / or sometimes there are threads of the cotton fabric attached to the food, thereby causing food contamination. Furthermore, even when applied only once, cotton fabrics are easily soiled and thus require laundering. [0003] Ho...
