Embodiment Construction

[0020] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0021] In a preferred embodiment, the PET film frosting glue component and content are:

[0022] PVB: 18kg

[0023] Matte powder (mainly silica): 2.2 kg

[0024] Ethanol: 150 kg

[0025] The production technology of described PET film frosting glue comprises the steps:

[0026] (1) Mix alcohol and matte powder according to the above weight ratio and stir the solution evenly;

[0027] (2) Slowly add the required PVB to the solution obtained in step (1) and stir evenly; the addition time is about 1 hour, and it takes about 30 minutes to stir evenly after the addition is completed.

[0028] (3) Seal and let it stand for defoaming, preferably more than 1 hour.

[0029] After the frosting glue is coated on the PET film, it can be firmly attached to the surface of the PET film and have a frosting effect, which avoids the process of physical grinding a...

Abstract

The invention provides a polyethylene terephthalate (PET) film frosted glue which comprises the components with the content: 18-22 parts of polyvinyl butyral (PVB), 1.6-2.4 parts of silica and 150-180 parts of silica, wherein 'part' represents unit mass. A preparation technology of the PET film frosted glue comprises the following steps of: (1) mixing the alcohol and the silica in proportion and evenly stirring the solution; (2) slowly adding the needed PVB into the solution obtained in the step (1), and evenly stirring; and (3) sealing, standing still and defoaming. The PET film frosted glue has the beneficial effects that after being spread onto a PET film, the PET film frosted glue can firmly attach on the surface of the PET film so as to lead the PET film to have frosting effect, the physical polishing process is omitted, and the cost can be reduced.

Description

Technical field [0001] The invention involves a PET membrane scrub glue. Background technique [0002] PET membrane, also known as film -resistant high -temperature polyester film, has excellent physical and chemical properties. First of all, PET film is well -transparent and shiny; it has good gas tightness and flavor.Secondly, the PET film has excellent mechanical properties, and its strong toughness is the best of all thermoplastic plastic. The strength and impact strength are much higher than the average film;For secondary processing, again, the PET film also has excellent heat resistance, cold resistance and good chemical resistance and oil resistance.Therefore, it can be widely used in the fields of magnetic records, light sensing materials, electronics, electrical insulation, industrial membranes, packaging and decoration and other fields.Most of the production process of most scrub PET membranes on PET membranes is mostly physically polished on the surface of the transpa...
