Description
Technical field
The present invention relates to a kind of brake material and its manufacturing method, more particularly to a kind of safe environment protection type brake ribbon and
Its manufacturing method.
Background technique
Perambulator is that infant's outdoor activities provide tool car that is convenient and designing, with implementing for middle state-two's tire policy,
Infant group increases, and social demand and output are stepped up.And child period be in life one it is the most fragile
Stage, while they are also very active active, and self-care viability is poor, if occur in perambulator use process emergency case or
When perambulator is parked in inclined-plane landform, perambulator at any time can it is out of control sliding and overturn and topple over, be easy to cause the danger that baby is greatest.Peace
Full property is the main index that perambulator is chosen.
Safety and environmental protection brake ribbon is critical component in perambulator brake.Safety and environmental protection brake ribbon major requirement: first is that by
It in being mounted in perambulator brake, is limited by installation space, size is small, the thin (stock size are as follows: 130mm* of thickness
12.7mm*3.2mm), camber is bent when use to be bonded on metal base, it is desirable that friction material has good toughness and strong
Degree；Second is that braking is realized on baby's lathe main shaft by anchor ear when causing danger, it is desirable that brake quick, gradual braking, friction
Coefficient is high；Third is that being required the selection of material feature of environmental protection high with baby child's close contact.
Conventional brake band is used as reinforcing fiber and antimony oxide, metal sulphur using aramid fiber, ceramic fibre, whisker etc.
The friction modifiers such as compound, braking process are easy to produce abrasive dust, belong to weak dissolved particles or fiber, environmental pollution, even
Infant is caused compared with major injury.
