Problems solved by technology

Therefore, the disadvantages of the known heat-insulating transparent adhesive tapes using the dry coating method or the wet coating method are that there are many processing steps, and the equipment cost is high and the production speed is low.
Moreover, the use of wet coating method also has environmental problems of waste solvents.

Embodiment 1

[0046] Production of heat-insulating polyvinyl chloride transparent tape 30 with a thickness of 0.2mm and a softness of 40PHR is as follows:

[0047] (1) According to the specific formula in Table 1, polyvinyl chloride resin, plasticizer, inorganic heat-insulating particles, additives (including modifiers, surfactants, dispersants and ultraviolet absorbers), stabilizers, lubricants After the raw materials are mixed evenly with a mixer, they are introduced into a 10,000-horsepower machine for even mixing;

[0048] (2) The temperature of the material is controlled at 160-180°C. After being gelled by the roller machine, the fully reacted mixture is made into a hot-melt adhesive cloth with a thickness of 0.2mm by calendering, and then introduced into water at a temperature of 20-85°C to cool and harden. ;

[0049] (3) After dewatering, the adhesive tape is introduced into the cooling wheel group to cool and set, and then coiled to obtain a heat-insulating polyvinyl chloride trans...

Embodiment 2

[0052] Except that the thickness is 0.3 mm, the raw material formula and preparation method of the heat-insulating polyvinyl chloride transparent tape 30 are the same as those in Example 1.

[0053] The test results are shown in Table 1, which shows that the heat-insulating transparent polyvinyl chloride adhesive tape 30 with a thickness of 0.3mm still has good transparency, infrared shielding rate and ultraviolet blocking rate, and there will be no precipitation of ATO during processing .

Embodiment 3

[0055] In addition to using air blowing, according to the specific formula in Table 1, use the method of Example 1 to produce a heat-insulating polyvinyl chloride transparent adhesive tape 30 with a thickness of 0.02mm and a softness of 40PHR.

[0056] The test results are shown in Table 1, which shows that the heat-insulating PVC transparent adhesive tape 30 with a thickness of 0.02mm has good transparency, infrared shielding rate and ultraviolet blocking rate, and there is no precipitation of ATO during processing.

Abstract

A transparent polyvinyl chloride coated fabric for heat insulation is made by the processing method of non-coating. The coated fabric has the function of shading infrared and ultraviolet. The preparation method is that polyvinyl chloride colophony containing special formula, plasticizer, inorganic thermal insulation particles and other mixtures of adding addition agent are used directly in the traditional process of making the polyvinyl chloride coated fabric, as a result, the transparent polyvinyl chloride coated fabric for thermal insulation not only has the existing physical properties of polyvinyl chloride, but also transparency, little fog, and excellent screening effect against infrared and ultraviolet.

Description

technical field [0001] The invention relates to a heat-insulating polyvinyl chloride transparent adhesive cloth, in particular to a heat-insulating polyvinyl chloride transparent adhesive cloth with the characteristics of shielding infrared rays and ultraviolet rays produced by a non-coating process. Background technique [0002] The known heat-insulating transparent adhesive film 10 shown in Figure 1 is a heat-insulating transparent article that can allow visible light to penetrate and can block infrared light. It is generally pasted on building glass or automobile glass to make the building glass Or automotive glass to achieve heat insulation effect and keep transparent visual requirements. [0003] However, the known heat-insulating transparent adhesive film 10 has poor ultraviolet light shielding effect. For this reason, ultraviolet light (UV) absorbers are added to the materials of architectural glass or automobile glass, so that architectural glass or automobile glass...
