Embodiment

[0029] ① Crushing: Select the trimmings of the corresponding grade and throw them into the crusher for crushing;

[0030] ② Ingredients: According to the formula, add the corresponding proportion of resin powder (commercially available sarin resin) and plasticizer, as well as corresponding additives, into the cone mixing irrigation, stir and mix until the material is ready (see Table 1);

[0031] ③ Metering and feeding: accurately adjust the proportion of corresponding raw materials through the weight loss scale and mix them into the extruder;

[0032] ④Extrusion: The corresponding proportion of resin powder, plasticizer and other additives are mixed into the extruder and then go through three stages: solid conveying zone, melting zone and melt conveying zone. The same amount of transported melt enters the distributor and is extruded from the die;

[0033] ⑤ Cooling and shaping: air cooling and water cooling, water cooling requires air knife to remove water, and oven drying; ...

Abstract

The invention belongs to the field of laminated glass, and particularly relates to an ionomer type laminated glass intermediate film and a preparation method thereof.The ionomer type laminated glass intermediate film is prepared by blending different surlyn resins and then conducting a tape casting technology, and through the content proportion of different types of acidic ionomer groups, the types and contents of various additives are adjusted, so that the ionomer type laminated glass intermediate film is obtained. And the use requirement of the photovoltaic module is met.

Description

technical field [0001] The invention relates to the field of laminated glass, in particular to an ionomer-type laminated glass interlayer film and a preparation method thereof. Background technique [0002] The domestic laminated glass interlayer film market is gradually maturing, and the market structure is gradually becoming clear: the low-end market is occupied by most domestic manufacturers, and each manufacturer desperately lowers costs and sales prices in order to seize market share, and the price war is quite fierce; the high-end market is dominated by imported products Occupied by individual domestic manufacturers, domestic brands rely on low prices to support only a small amount of market share; the real high-end market is still monopolized by imported products, and domestic ionic interlayers (SGP interlayers) have no ability to shake . It is worth noting that the domestic laminated glass interlayer film is entering the international market and gradually increasing...
