With the increasing awareness of environmental protection and the increasing shortage of global resources, the use of recycled materials has become an important development direction of the plastics industry. Among them, ethylene propylene diene (EPDM) recycled rubber powder, as a high-quality recycled material, has achieved remarkable results in plastic PP modification. Free provision of EPDM recycled rubber powder added to plastic PP modified reference formula and process flow, is expected to allow more enterprises to reduce costs and open up the market.
EPDM recycled rubber powder is a kind of recycled material obtained by the process of selection, cleaning, crushing and screening of waste rubber products, with the following characteristics:
1. Excellent physical and mechanical properties: EPDM recycled rubber powder has good tensile strength, compressive strength and elastic modulus, making it an ideal plastic modified material.
2. Strong weather resistance: EPDM recycled rubber powder can show good heat resistance, ultraviolet resistance and corrosion resistance in outdoor environment, making plastic products more durable.
3. Good resilience: EPDM recycled rubber powder has excellent resilience, which can improve the flexibility of plastic products and reduce the deformation rate.
EPDM recycled rubber powder plastic PP modified reference formula
Formula 1: 100 parts of polypropylene (PP), 10-30 parts of EPDM recycled rubber powder (can be adjusted appropriately according to needs).
Formula 2: 100 parts of polypropylene (PP), EPDM recycled rubber powder: 30-50 parts (can be adjusted according to needs).
5 parts of plasticizer, 2 parts of stabilizer, 3 parts of flame retardant
According to thespecific application requirements of the modified plastic, appropriate adjustments can be made according to the above formula, and experimental verification is carried out to obtain the best modification effect.
Refer to theprocess flow of adding EPDM recycled rubber powder to plastic PP modification:
1. Raw material ratio: accurately weigh polypropylene and EPDM recycled rubber powder according to the selected formula ratio.
2. Pretreatment: Add plasticizers, stabilizers and flame retardants as needed, and premix EPDM recycled rubber powder with polypropylene to ensure uniform distribution of the two.
3. Mixed melting: The pretreated mixture is sent to the extruder for melt mixing.
4. Extrusion: The molten modified material is extruded through the extruder in the desired shape.
5. Cooling and curing: The extruded plastic products are quickly cooled by cooling equipment to solidify and form.
6. Testing and qualitycontrol: necessary testing is carried out on the finished product to ensure that it meets the expected physical properties and quality requirements.
As a high-quality recycled material, EPDM recycled rubber powder has broad application prospects in the field of plastic PP modification. Through the reasonable selection of formula ratio and correct process flow, the modification of plastic PP can be realized, the performance and service life of plastic products can be improved, and the cost of raw materials can be reduced under the premise of ensuring the quality of modified plastics. If you have a better way to modify PP plastics, welcome us to further in-depth discussion, in order to continuously improve the addition of EPDM recycled rubber powder to plastic PP modification technology, and promote the application and development of environmentally friendly recycled materials.
