Described phenolic resin is phenol-formaldehyde resin modified.
Described lapping paste comprises one or more mixing of aluminium sesquioxide, iron oxide and zirconium silicate; Described oiling agent comprises one or more mixing of graphite, molybdenum disulfide and mica.
Wherein, phenol-formaldehyde resin modified: after phenolic resin modified, the impact toughness of phenolic resin, cementability, mechanical strength, heat resistance, flame retarding, dimensional stability, curing rate and moulded manufacturability philosophy are improved.
Reinforcing material mineral fibre: the brake lining of production has the distinguishing features such as braking is steady reliably, high-temperature behavior is good, wear away little, low (nothing) noise, the life-span is long.
Lapping paste adopts iron oxide to add in friction material, can adjust the friction factor of braking material; Oiling agent employing graphite etc. can reduce the heat fade of friction material, stablizes the friction factor of friction material, can play good anti-attrition effect and self-lubricating function, can effectively protect antithesis dish again.
Filler is used barium sulphate, stable chemical nature, and nonmagnetic toxicity, has good flame resistance; Calcium carbonate, in use can vibration damping, anti-skidding, and noise reduction is inhaled ripple; Good combination property, friction factor is high, and wear-resisting property and resistance to heat are high; Stable friction performance, heat fade and hot restorability are better, high temperature friction and wear superior performance, life of product can improve 30%; Can reduce the virtue fiber that falls, red copper, the consumption of the high value materials such as potassium titanate, reduces friction material cost greatly.
Tyre talc claims again rubber break flour, is the tire glue face that claims junked tire, removes curtain radial, and pulverizing processes.Composition cured natural rubber and butylbenzene vulcanizate.As elastic filler, for friction material, work to increase wearing away the effect of making an uproar.
Potassium titanate lamella crystal, there is very good physical and mechanical properties: high strength, high-modulus, high heat-resisting, heat insulation, electrical insulation properties and excellent properties of infrared reflection, because its chemical property is very stable, good with plastics compound phase capacitive, show good antifriction consumption and lubricity and outstanding dimensional stability.With glass, compare with carbon fibre, have micro-populatedly, moulding article dimensional accuracy and good stability, smooth surface, to many significant advantages such as equipment and mold wearing and tearing are little.Its packing density is larger, can reduce the environmental pollution that dust from flying causes.Add that it can solve " brake noise " that betides braking device completely, the working life of friction factor, raising braking travelling comfort and increase braking plate during Simultaneous Stabilization high temperature.
Aramid fibre pulp carries out obtaining after surface fibrillation processing to aramid fibre, and its unique surface structure has greatly improved the grasping force of mixture, is therefore suitable as very much a kind of reinforcing fiber and is applied in friction and sealed product.Light yellow wadding is flower-shaped, be lint shape, its filoplume is abundant, intensity is high, good stability of the dimension, without fragility, high temperature resistant, corrosion-resistant, flexible, shrinkage is little, wear resistance good, surface area is large, can well be combined with other material, it is a kind of reinforcing material, moisture regain is 8%, and Mean length is 2-2.5mm, and surface area is 8m2/g.And be used as pad reinforcing material, and there is good resilience and sealability, health and environment, without harm, are only needed to add the pulp that be less than 5% conventionally, the intensity that obtains product is equivalent to the product that 50-60% asbestos fiber strengthens.Be used for strengthening the manufactured good such as friction, sealing material, can be used as the alternative of asbestos for friction sealed material, high performance heat resistant insulating paper and reinforced composite.It is a kind of intensity material of main part of extraordinary enhancing friction plate.
Polyacrylonitril fiber has high-modulus, high temperature resistant, wear-resisting, corrosion-resistant, heat transfer, density is little and thermal expansion coefficient is little.In friction material, be generally used for the expensive goods that performance is higher, there is high temperature friction stable performance, the advantage such as wear and tear low.
Red copper fiber has heat absorption, rapid heat dissipation, and resistant to elevated temperatures feature, while mixing with other materials, can improve cohesive force and uniformity coefficient.
The present invention is that the fusing point that utilizes polyacrylonitril fiber to have is high, stable and the potassium titanate lamella crystal of high-modulus, compression performance has the advantages such as fabulous chemicals-resistant stability, functional stabilization is good, pliability is good and designs for friction material formulation, add again potassium titanate lamella crystal, can guarantee high temperature friction performance, make product less at high temperature wear, do not damage friction pair, reduce brake noise, overcome heat cracking, reduce environmental pollution etc.
