Example Embodiment

[0034] Example 1: Mix 100 grams of chlorobutyl rubber and 30 grams of chlorinated polyethylene at a temperature of 160°C for 20 minutes on a twin-roll rubber mixer, and then add 20 grams of phenolic resin and 5 grams of zinc oxide at 30°C , 0.5 g of magnesium oxide, 1 g of stearic acid and 15 g of chlorinated paraffin. After the rubber material is mixed evenly, thinly pass it, make a triangle bag and roll it 5 times each, adjust the roll distance to 2mm, and leave it for 24 hours for use. The mixed rubber was molded on a flat vulcanizer at a temperature of 160° C. and a pressure of 10 MPa for 15 minutes to obtain a sample. The dynamic mechanical properties of materials are characterized by dynamic mechanical testing analyzer, such as figure 1 shown. The results show that the peak height of mechanical internal friction of the material is 1.72, the temperature corresponding to the maximum loss factor is +16.5℃, and the temperature range of the loss factor greater than 0.7 is ...

Example Embodiment

[0035] Example 2: 100 grams of chlorinated butyl rubber and 30 grams of chlorinated polyethylene were mixed at room temperature for 20 minutes on a double-roller rubber mixer, and then 20 grams of phenolic resin, 5 grams of zinc oxide, Magnesium oxide 0.5g, stearic acid 1g and chlorinated paraffin 10g. After the rubber material is mixed evenly, thinly pass it, make a triangular bag and roll it 5 times each, adjust the roll distance to 3mm, and leave it for 24 hours for use. The mixed rubber was molded on a flat vulcanizer at a temperature of 170° C. and a pressure of 8 MPa for 10 minutes to obtain a sample. The dynamic mechanical properties of materials are characterized by dynamic mechanical testing analyzer, such as figure 2 shown. The results show that the peak height of mechanical internal friction of the material is 1.56, the temperature position corresponding to the maximum loss factor is +13℃, and the temperature range with loss factor greater than 0.7 is -19~+67℃. ...

[0036] Example 3: 100 grams of chlorinated butyl rubber and 30 grams of mechanically degraded chlorinated polyethylene (that is, crushed on a vibrating ball mill for 12 hours) were mixed at a temperature of 140° C. 20 grams of phenolic resin, 1.5 grams of zinc oxide and 5 grams of chlorinated paraffin were added at 60°C. After the rubber material is mixed evenly, thinly pass it, make a triangle bag and roll it 5 times each, adjust the roll distance to 2mm, and leave it for 24 hours for use. The mixed rubber was molded on a flat vulcanizer at a temperature of 150° C. and a pressure of 8 MPa for 15 minutes to obtain a sample. The dynamic mechanical properties of materials are characterized by dynamic mechanical testing analyzer, such as image 3 shown. The results show that the peak height of mechanical internal friction of the material is 1.74, the temperature position corresponding to the maximum loss factor is +12.5℃, and the temperature range of the loss factor greater tha...

Abstract

This invention discloses a kind of butyl rubber/polyolefin chloride blend composite damping materials and its preparation method. It has the characteristics that 70 mass shares of butyl rubber and 30~100 mass shares of polyolefin chloride are blended in a double-roller glue cauldron or an extruder at a temperature of 100~160 deg. C for 5~20 minutes or directly in a double-roller glue cauldron at room temperature for 5~20 minutes. Then at a temperature of 30~60 deg. C, 9~30 mass shares of vulcanizing agent, 1.5~6.0 mass shares of auxiliary vulcanization agent and 5~15 mass shares of plasticizers are added and the homogeneous blend is compression molded in a hydraulic plate vulcanization machine at a temperature of 140~170 deg. C and a pressure of 5~10MPa for 10~30 minutes so as to produce butyl rubber/polyolefin chloride blend composite damping materials with extraordinary damping properties.

Description

technical field [0001] The invention relates to a butyl rubber / chlorinated polyolefin blended vulcanized composite damping material and a preparation method thereof, belonging to the field of polymer material molding and processing. Background technique [0002] Rubber-like polymer damping material, namely viscoelastic damping material, is a functional material that can effectively absorb vibration energy. It can be converted into heat energy and dissipated, thus having the effect of reducing vibration and noise. Polymer damping materials are widely used in military and high-tech fields such as missiles, naval ships, rockets, and satellites. With the increasing emphasis on environmental protection, it has been applied in civilian industries such as cars, precision instruments, and earthquake prevention in recent years, and has developed extremely rapidly. [0003] Generally, the glass transition temperature (Tg) transition zone of a polymer homopolymer is relatively narrow...
