Product Details
Recycled rubber sheet extruder
There is a waterproof building material additive formulated with rubber particles. The new roof material made from it can reduce the brittleness temperature, enhance the flow temperature and reduce the penetration. This roofing material is a new type of waterproof roofing material. It is produced in the form of wide flexible strips and consists of multiple layers. The middle layer is fiberglass cloth made of fine glass fibers. This layer determines the strength properties of the material. Coat both sides with modified asphalt with a thickness of 300 Å, and apply polyethylene film with a thickness of 100 Å on the outside, top and bottom. These membranes prevent roof waterproofing materials from sticking to each other when they are packaged in rolls for transportation. The roll length of this material is approximately meters. When this material is used to cover flat roofs and remaining roofs of houses and production workshops, a blowtorch is used to heat the asphalt. At this time, the polyethylene film melts away, and the asphalt modified layer sticks to the roof surface, and the asphalt layers can be bonded to each other. Usually, the roof is coated so that the total thickness of the roof covering is . The top layer is sometimes not a polyethylene film layer, but a granite sub-layer, which protects the roof material from the effects of light. In addition, it can also be produced by large enterprises and can be widely used in waterproofing roofs of houses at different levels in various cities. Use of waste rubber powder and resin together
_
Generally speaking, waste rubber powder can be filled with all thermoplastic resins, but the most practical ones are resins, etc. Thermoplastic resin mixed with waste rubber powder can be processed into products by molding, lamination, calendering and injection molding. Waste rubber powder and resin can be mixed with simple blending method and dynamic desulfurization method. Compared with the simple blending method, the dynamic desulfurization method contains a vulcanizing agent in the formula, which can cause the generation of waste rubber powder between waste rubber powder, waste rubber powder and compatibilizer, or waste rubber powder and resin on the basis of ensuring that the materials are evenly mixed. cross-linking reaction. Since the waste rubber powder itself has a cross-linked structure and has a large particle size, during the blending process, even if the mass ratio of waste rubber powder to resin is //, the waste rubber powder can easily become a dispersed phase and be dispersed evenly. The process It is easier to control and requires less processing equipment. Polyolefin/waste rubber powder plastic elastomer can be used to produce sealing strips, roof and floor paving materials, fence posts, sleeper pads, anti-slip pads, shoe soles, fenders, wheels, sprinkler bucket covers and other products. Adding vulcanized rubber powder to the soles can improve the flexibility of the soles. Tests have proven that soles without vulcanized rubber powder will break after tens of thousands of flexings, while soles with vulcanized rubber powder will not break after tens of thousands of flexings.
