Embodiment 1

[0036] refer to Figure 1-3 , a preparation method of a sound insulation film, comprising the following steps:

[0037] S1: Heating and mixing, 230 parts of polyvinyl chloride, 160 parts of polyethylene, 55 parts of polypropylene, 60 parts of polystyrene, 130 parts of polytetrafluoroethylene, 45 parts of additives, 40 parts of shellac, 25 parts of rosin, and phenolic resin Put 55 parts into the mixer and mix, heat during mixing, and keep stirring and mixing during heating;

[0038] S2: The casting sheet is stretched, and the mixed raw materials are added to the casting machine for casting treatment to obtain a thin film thick sheet. The thickness of the thin film thick sheet is 3500 μm. And through the film biaxial stretching machine, the film thick sheet is stretched to obtain the semi-finished film;

[0039] S3: trimming, after the semi-finished film is cooled for 8 minutes, the cooled semi-finished film is trimmed by an edge trimmer;

[0040] S4: corona treatment, the se...

Embodiment 2

[0049] refer to Figure 1-3 , a preparation method of a sound insulation film, comprising the following steps:

[0050] S1: Heating and mixing, 170 parts of polyvinyl chloride, 130 parts of polyethylene, 75 parts of polypropylene, 85 parts of polystyrene, 145 parts of polytetrafluoroethylene, 56 parts of additives, 49 parts of shellac, 26 parts of rosin, and phenolic resin Put 77 parts into the mixer and mix, heat during mixing, and keep stirring and mixing during heating;

[0051] S2: The casting sheet is stretched, and the mixed raw materials are added to the casting machine for casting treatment to obtain a thin film thick sheet. The thickness of the thin film thick sheet is 2300 μm. And through the film biaxial stretching machine, the film thick sheet is stretched to obtain the semi-finished film;

[0052] S3: trimming, after the semi-finished film is cooled for 6 minutes, the cooled semi-finished film is trimmed by an edge trimmer;

[0053] S4: corona treatment, the semi...

Abstract

The invention relates to the technical field of sound insulation films, and discloses a preparation method of a sound insulation film, which comprises the following steps: S1: heating and mixing 160-300 parts of polyvinyl chloride, 120-200 parts of polyethylene, 40-80 parts of polypropylene, 50-90 parts of polystyrene, 120-150 parts of polytetrafluoroethylene, 30-60 parts of an additive, 30-55 parts of lac and 20-30 parts of rosin. Which comprises a film body 4 and is characterized in that a first sound insulation resin layer 3 and a second sound insulation resin layer 5 are bonded to the top and the bottom of the film body 4 respectively, and a plurality of hollow insulation particles 6 are arranged in the first sound insulation resin layer 3 and the second sound insulation resin layer 5 respectively. The hollow insulating particles block sound to a certain degree, the sound insulation effect of the sound insulation film is improved, and the antibacterial agent is added, so that the film has great antibacterial performance, and the film is safer to use.

Description

technical field [0001] The invention relates to the technical field of film preparation, in particular to a sound insulation film and a preparation method thereof. Background technique [0002] With the process of urbanization, urban noise pollution has become a major obstacle to people's health and high-quality life after air pollution. It has been listed as one of the three major environmental hazards affecting human living conditions in the world today. The main sources include traffic noise, social noise and industrial noise, etc. The above-mentioned noise pollution will have adverse effects on people's psychology and physiology. [0003] The noise problem is an important issue that needs to be solved urgently in the field of environmental engineering. In order to solve the noise problem, various sound insulation products have emerged as the times require, among which there are sound insulation films. The actual sound insulation effect of the film is relatively low, the...
