Embodiment 1

[0059] To produce transparent heat-insulating polyvinyl chloride tape 30 with a thickness of 0.2mm and a softness of 40PHR, the preparation method is as follows:

[0060] According to the specific formula in Table 1, the inorganic heat-insulating particles LaB 6 Raw materials such as additive amount 0.25PHR, modifier 0.81PHR, dispersant 0.17PHR, ultraviolet absorber 0.8PHR, stabilizer 3PHR, plasticizer 40PHR and polyvinyl chloride resin 100PHR were put into the mixer in order (manufactured by HenschelMixer N.P.C, 300L) After mixing evenly, introduce a 10,000-horsepower machine (manufactured by N.P.C, 100L drop-door type) to mix evenly;

[0061] After being gelled by two roller-type roller machines (manufactured by N.P.C, roller speed difference 1:1.15), the temperature of the material is controlled at 150-190°C, and the material is sent to a four-wheel reverse L-shaped calender (manufactured by N.P.C, specification 24″ ×72″), hot-melt adhesive cloth with a thickness of 0.2mm....

Embodiment 2

[0065] According to the specific formula in Table 1, the inorganic heat-insulating particles CeB 6 Addition amount of 0.25 PHR, modifier 0.81 PHR and other raw materials were produced using the method of Example 1 to produce a transparent heat-insulating polyvinyl chloride tape 30 with a thickness of 0.2 mm and a softness of 40 PHR.

[0066] The test results are shown in Table 1, the light transmittance is as high as 70%, and the haze is 2.0%, which shows that the prepared transparent heat-insulating polyvinyl chloride adhesive tape 30 has transparency, and its light transmittance is slightly lower than that of Example 1. Its infrared shielding rate is 64%, second only to Example 1, and its ultraviolet shielding rate is 99%, and the inorganic heat-shielding particles will not precipitate during the processing.

Embodiment 3

[0068] According to the specific formula in Table 1, the raw materials such as the addition amount of inorganic heat-insulating particles ATO 1.8PHR, LaB6 addition amount 0.25PHR, modifier addition amount 6.97PHR, etc., were produced using the method of Example 1 to produce a transparent glass with a thickness of 0.2mm and a softness of 40PHR. Heat insulation polyvinyl chloride tape 30.

Abstract

The invention relates to a transparent heat insulation polyvinyl chloride rubberized fabric prepared in a non-coating processing mode and a preparation method thereof. The prepared rubberized fabric has the infrared and ultraviolet blocking energy-saving effect. The preparation method comprises the following steps of: mixing a heat insulation material and an auxiliary agent for modification and stirring the mixture uniformly, properly dispersing the heat insulation granules, and mixing the dispersed heat insulation granules, polyvinyl chloride resin, plasticizer and auxiliary agent in turn; and directly guiding the rubberized mixture to a rubberized fabric machine for rolling and the like. The rubberized fabric produced by the method has the physical properties of good heat insulation effect, transparency and the like.

Description

technical field [0001] The invention is a transparent heat-insulating and energy-saving polyvinyl chloride tape produced by a non-coating processing method. It has good infrared and ultraviolet light shielding effects, and then achieves the purposes of heat insulation and protection. The finished product is suitable for building glass, automobile windows, refrigerated storage display cabinets and products with energy-saving demands. Background technique [0002] There are two main sources of heat energy generated by sunlight, including visible light with a wavelength of 400nm to 700nm and infrared light with a wavelength of 700nm to 1800nm ​​(belonging to the non-visible light range), which are generally used in building glass, car windows, Refrigerated storage display cabinets and products with energy-saving appeals must not only have the requirement of visual transparency, but also have the effect of blocking the heat generated by infrared light. Therefore, materials with ...
