Problems solved by technology

Although EVA is much cheaper than TPU in terms of price, the physical properties of EVA are worse than those of PVC and TPU. Especially in the application of inflatable / water-filled products, it must have good resilience and tensile strength. EVA is poor in this feature and naturally suffers from many limitations
[0006] After the current search, there is no relevant technology related to the application of polyolefin plastic materials in inflatable / water-filled products, and the application of polyolefin plastic materials in inflatable / water-filled products has not been found in the market, mainly because the general polyolefin Plastic materials have no resilience and are not suitable for high frequency welding processing

Embodiment ( 1

[0024] The design formula is as follows in Table 1:

[0025] raw material name

[0026] On-line trial production on the tape machine. After weighing the raw materials according to the design formula in Table 1, put them into the kneading / mixing function of the 10,000-horsepower machine (banbury mixer) for gelation and aging. The operation time is 90 seconds, and then the mature rubber Send it to a kneader (roller) with a set temperature of 150°C for uniform kneading, and then feed the rubber into a calender with an operating temperature of 160-190°C in a continuous operation mode, and roll it into The hot-melt adhesive film with a thickness of 0.30mm is pressed by an embossing wheel, cooled to room temperature by a cooling wheel, and finally coiled by a coiler to obtain a non-halogen film product for blowing.

Embodiment ( 2

[0028] The design formula is as follows in Table 2:

[0029] raw material name

[0030] After weighing the raw materials according to the formula in Table 2, knead and process them with a two roll mil in the laboratory. The temperature of the rolls: 145°C for the front roll and 140°C for the rear roll. The kneading time: 10 minutes. Finally, adjust the gap between the two wheels to make the rubber material rolled to the required thickness, and finally take out the film to cool it, and make a non-halogen film for air blowing with a thickness of 0.30mm.

Embodiment ( 3

[0032] The design formula is as follows in Table 3:

[0033] raw material name

[0034] After weighing the raw materials according to the formula in Table 3, knead and process them with a two roll mil in the laboratory. The temperature of the rolls: 175°C for the front roll and 170°C for the rear roll. The kneading time: 10 minutes. Finally, adjust the gap between the two wheels to make the rubber material rolled to the required thickness, and finally take out the film to cool it, and make a non-halogen film for air blowing with a thickness of 0.30mm.

Abstract

The invention provides a non-halogen film for inflation and the preparation thereof. The film is made from 20-80 phr (parts per hundred of resin) of thermoplastic polyolefine elastomer, 80-20 phr of polyolefine polymer, 1-50 phr of high-frequency weld modifier, 0.1-5 phr of lubricant, 0.1-5 phr of antioxidant, 0-50 phr of bulking agents and 0-15 phr of colorant. The preparation of the film is as follows: subjecting a batch mixture to a mixing / mulling device for gelatination, uniformly mixing, making a hot-melting adhesive film by using a calendering machine, cooling and coiling to obtain the no-halogen film for inflation. The film is environment-friendly, free of halogen, recoverable and suitable for high-frequency welding, has similar property to the polyvinyl chloride (PVC) film; and is used to replace the conventional PVC film for inflation.

Description

technical field [0001] The invention relates to a non-halogen film for air blowing and its preparation. The film is an environmentally friendly material without halogen, can be recycled and reused repeatedly, and its physical properties will not be affected. The characteristics of the non-halogen film for air blowing of the present invention, such as hand feeling, resilience, tensile strength and high-frequency welding, are similar to those of conventional polyvinyl chloride (PVC) air blowing films, and can replace PVC in inflatable / water-filled products Applications, such as: inflatable toys, inflatable furniture, air beds, water bags and water beds, etc. Background technique [0002] Plastic products have been widely used in daily life, and polyvinyl chloride (PVC) has very good high-frequency processability. High-frequency processing can greatly improve the speed and convenience of welding, so the common welding method for PVC is high-frequency processing. And PVC has go...
