Embodiment 1

[0036] First, as Figure 1-7 As shown, the present invention provides a formula of a CPP film, including a CPP film, the CPP film is composed of a CPP base film and a coating layer, and the CPP film also includes the following components:

[0037]

[0038] A composite slurry is prepared by mixing nano-silica and sodium caseinate, which is mixed with CPP resin and cast to form a film to obtain a CPP base film. The polymer microemulsion is composed of 15-25% emulsifier and 60% water. -70% mixed with water-based initiator 10-15%.

[0039] In this embodiment, dicyandiamide, chitosan, glycerin, nano-silica and sodium caseinate are mixed and stirred according to the proportion, and then mixed with CPP resin to form a film block, and then proportioned and applied. The formula of the layer is a polymer microemulsion made by mixing 15-25% of emulsifier, 60-70% of water and 10-15% of water-based initiator, and then mixed with antistatic masterbatch and toughening agent to make spra...

Embodiment 2

[0041] Second, as Figure 1-7 As shown, the present invention also provides a production process of a CPP film formulation, the production process of the formulation of the CPP film, comprising the following steps:

[0042] Step 1, stirring and mixing the composite slurry;

[0043] Step 2, preparing the CPP base film;

[0044] Step 3, prepare the coating layer;

[0045] Step 4, packing CPP film;

[0046]Step 1 also includes: injecting chitosan, dicyandiamide and glycerin into the stirring device according to the proportioning ratio, and placing nano-silicon dioxide and sodium caseinate inside the stirring device for mixing and stirring, and the second step further includes: The mixed materials are placed inside the preparation container, mixed with CPP resin and solidified to form a film to obtain a CPP base film, and then the polymer microemulsion, antistatic masterbatch and toughening agent are sprayed on the surface of the CPP base film by a spraying mechanism. Thereby,...

Embodiment 3

[0049] like Figure 1-7 As shown, on the basis of Example 2, the present invention provides a technical solution: preferably, the preparation container includes a shell body 1, a spraying device 2, a moving groove 3 and a container plate 4, and the top of the shell body 1 is fixedly installed with a spray coating Equipment 2, a moving groove 3 is opened on one side of the main body 1 of the casing, a container plate 4 is movably installed inside the moving groove 3, a cleaning channel is opened on one side of the container plate 4, and a preparation groove 41 is opened inside the container plate 4. Sliding slots 45 are arranged on both sides of the inside of the slot 41, and a sliding column 44 is arranged inside the sliding slot 45. A sliding block 43 is movably installed on the outer side of the sliding column 44, and a telescopic rod 46 is arranged on one side of the sliding block 43. The other end of the sliding block 43 is fixedly connected to the inside of the sliding gr...

Abstract

The invention discloses a formula and a production process of a CPP membrane, and relates to the technical field of polymeric membranes, the CPP membrane is composed of a CPP base membrane and a coating layer, and the CPP membrane further comprises the following components: 4-12% of dicyandiamide, 12-16% of nano-silica, 5-10% of sodium caseinate, 25-45% of glycerin, 12-23% of chitosan, 4-12% of an antistatic master batch, 3-6% of a polymer microemulsion, and 8-14% of a toughening agent. The two ends of the limiting shaft are limited and fixed through the damping rings, then the extrusion blocks and the buffering pressing columns are matched with each other, the extrusion blocks are driven to extrude the two ends of the limiting shaft through the telescopic elasticity of the buffering pressing columns, the compressing and fixing functions are achieved, the buffering pressing layers and the compressing pads are matched with each other, the buffering pressing layers are stressed to extrude the elastic blocks, and the elastic blocks extrude each other and cooperate with the rebound resilience of the elastic blocks, so that the function of buffering the acting force is achieved, the problem that the cleaning mechanism is poor in fixity and easily shakes is solved, the stability of the device is improved, and the cleaning efficiency of the cleaning mechanism is improved.

Description

technical field [0001] The invention relates to the technical field of polymer films, in particular to a formula of a CPP film and a production process thereof. Background technique [0002] High-density polyethylene is a highly crystalline, non-polar thermoplastic resin. CPP has excellent resistance to most household and industrial chemicals. The polymer is non-hygroscopic and has good water vapour resistance for packaging applications. CPP has good electrical properties, especially high insulation dielectric strength, making it very suitable for wires and cables. In the production and use of the existing CPP black and white two-color film, the yellow waste oil in the asphalt penetrates into the surface of the CPP film, making the film yellow and affecting the appearance. At the same time, there is nitrogen in the production. Catalyst poisoning caused by silicone oil process. The following problems exist for the prior art: [0003] 1. When the container equipment prepa...
