Simplified title:PC钢绞合线的防锈覆膜双重结合结构形成加工方法以及PC钢绞合线 METHOD OF FORMING DOUBLE-BONDED CORROSION PROTECTION COATINGS ON PRESTRESSING STRAND AND PRESTRESSING STRAND
Abstract in simplified Chinese:一种PC钢绞合线的防诱覆膜双重结合结构形成加工方法,由以下工序构成:扭绞PC钢绞合线并从侧面线放松芯线以进行基体调整的前处理工序;一次喷涂工序,在表层部形成树脂覆膜;二次喷涂工序,在一次喷涂工序后,在侧面在线形成一部分形成双重结合覆膜的分别处於单独状态的树脂覆膜;二次喷涂工序之后,相对于芯线以原始状态绞接侧面线,以使双重结合覆膜部分比特于绞合线的表层部的工序,根据本发明的方法,绝对不会影响柔软性以及与混凝土的附着强度的特性,在担心特殊结构的物体会损坏覆膜时能够保护暴露的外表面,并能容易地形成较厚的双重结合覆膜。

Abstract:
PROBLEM TO BE SOLVED: To provide an extra fine plated steel wire having excellent adhesiveness to rubber, whose productivity is not impaired, whose drawing workability is not degraded, and which has excellent adhesiveness to rubber with Co salt not blended therein, and whose adhesive strength is less degraded even with the lapse of time. SOLUTION: The extra fine plated steel wire has a double layer plating on its surface. The wire diameter is 0.1-0.4 mm. The double layer plating of the extra fine plated steel wire having excellent adhesiveness to rubber includes a covering Cu plating having the average thickness of 20-500 nm provided on the surface of the steel wire, an adhesive Cu plating of the average thickness of 10-50 nm provided on the outermost layer, and a diffusion preventive layer provided between the covering Cu plating and the adhesive Cu plating. The diffusion preventive layer is preferably any one of an Ni, Co and Cr plating layers of the average thickness of 2-25 nm. COPYRIGHT: (C)2012,JPO&INPIT
Abstract:
Composite reinforcer (R-2) self-adhesive, by curing, to a diene rubber matrix, which can be used as reinforcing element for a tire, comprising: one or more reinforcing thread(s) (20), for example a carbon steel cord; a first layer (21) of a thermoplastic polymer, the glass transition temperature of which is positive, for example, a polyamide 6,6, covering individually said thread or each thread or collectively several threads; a second layer (22) comprising a functionalized diene elastomer bearing functional groups selected from epoxide, carboxyl, acid anhydride and acid ester groups, for example, an epoxidized natural rubber, covering the first layer (21). Process for manufacturing such a composite reinforcer and rubber article or semi-finished product, especially a tire, incorporating such a composite reinforcer.
