Embodiment Construction

[0026] see figure 1 Shown:

[0027] The production process step of a kind of durable polyvinyl butyral PVB intermediate film of the present invention is as follows:

[0028] Step 1: Ingredients

[0029] Take 3.848kg of ultraviolet absorber, 1.924kg of anti-aging agent, and 0.928kg of antioxidant, add it to 253.3kg of plasticizer and heat it up to 60°C to let it fully dissolve, then cool down to 40°C to make a plasticizer liquid mixture and put it in the storage Stand-by in the liquid tank 1, wherein the ultraviolet absorber is UVP-327, and the composition is 2-(2'-hydroxyl-3', 5'-di-tert-phenyl)-5-chlorinated benzotriazole; anti-aging agent It is phosphite, molecular formula: C42H6303P; the antioxidant is antioxidant 1076, the name is octadecyl propionate, molecular formula: C35H6203; the plasticizer is triethylene glycol diisocaprylate, molecular formula: C22H4206;

[0030] Step Two: Extrude

[0031] (1), adding of the plasticizer liquid mixture: use the metering jet pump...

Abstract

The invention discloses a production process and a production system of durable PVB (polyvinyl butyral) intermediate films. The production process includes: the first step of preparing, the second step of extruding, the third step of casting and the fourth step of forming and packaging. The production system consists of a liquid storage tank, a storage bin, an extruder, a rotary plate type fuse filter, a mould head, a water cooling device, a drying device and a control device, wherein the liquid storage tank and the storage bin are connected with the extruder, the extruder is connected with the rotary plate type fuse filter, the rotary plate fuse filter is connected with the mould head through a metering pump by the aid of pipelines, the water cooling device is arranged at the rear end of the mould head, and the drying device is arranged behind the water cooling device. The production process and the production system have the advantages that the produced intermediate films are uniform in thickness, fine in durability, low in energy consumption and production cost, stable in quality and capable of being produced in industrialization.

Description

technical field [0001] The invention relates to a production process and a production system of a polyvinyl butyral interlayer film, in particular to a production process and a production system of a durable polyvinyl butyral PVB interlayer film. Background technique [0002] PVB film is mainly used for laminated glass, which is to sandwich a layer of PVB film with polyvinyl butyral resin as the main component between two pieces of glass. PVB laminated glass can be widely used in the construction industry, automobile industry, aviation industry, and financial industry due to its multiple functions such as safety, heat preservation, noise control, and UV isolation, and is especially suitable for bulletproof glass. There are many defects, resulting in uneven thickness of the produced PVB film, and poor durability. It is prone to aging under certain irradiation, and will lose its effectiveness due to aging in a short period of time, causing the laminated glass to fail to meet t...
