Embodiment 1

[0045] 100 parts of PVC resin, 3.5 parts of stabilizer, 25 parts of plasticizer, 20 parts of flame retardant (the contents of antimony trioxide and phosphate flame retardant are 4 parts and 16 parts respectively), 18 parts of adhesive modified After the additive and the required color pigment are mixed evenly, they are kneaded in an internal mixer to a molten and plasticized state, transported to a calender, pressed, extended and cooled to form a PVC film B layer with a thickness of 0.08mm and a thickness of 0.08mm The black layer of PVC film, the pigment used in the black layer of PVC film is black pigment. After mixing 100 parts of PVC resin, 3.5 parts of stabilizer, 25 parts of plasticizer, 20 parts of flame retardant (the contents of antimony trioxide and phosphate flame retardant are 4 parts and 16 parts respectively) and pigments, the Knead in an internal mixer to a molten and plasticized state, transport to a calender, press, extend and cool to form a layer A of PVC fil...

Embodiment 2

[0050] The glass fiber / PVC composite membrane material S2 of the present embodiment is prepared in the same steps as in Example 1, the difference is that in step (1), 100 parts of PVC resin, 3.5 parts of stabilizer, 30 parts of plasticizer, 18 parts of flame retardant (the contents of antimony trioxide and phosphoric acid ester flame retardant are 6 parts and 12 parts respectively, after 18 parts of adhesion modifier and required color pigment are mixed evenly, knead in the internal mixer to Molten state, after cooling, roll into the calender, press and stretch to form PVC film B layer, PVC film black layer, the pigment used in the PVC film black layer is black pigment.

Embodiment 3

Abstract

The invention provides a glass fiber / PVC (polyvinyl chloride) composite membrane material. The glass fiber / PVC composite membrane material comprises a first PVC membrane layer, a second PVC membrane layer, a glass fiber base fabric layer and a third PVC membrane layer from bottom to top in sequence, wherein the second PVC membrane layer is a black PVC membrane layer. The invention also provides a preparation method for the glass fiber / PVC composite membrane material. The glass fiber / PVC composite membrane material provided by the invention has good shading and thermal insulation performances on the premise of ensuring good comprehensive color fastness and combustion performances. The preparation method for the glass fiber / PVC composite membrane material, provided by the invention, is simplified in the process and easy to perform.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a glass fiber / PVC composite film material and a preparation method thereof. Background technique [0002] The membrane structure is composed of fabrics (membranes) with excellent performance through supporting members (such as rigid beams, columns, flexible cables), or pressurizing the air in the membrane to combine in a certain way and apply appropriate initial pretension to form a certain rigidity. The shape of the space structure, so as to bear a certain external load in a form of space structure. The early membrane structure has been stagnant due to the slow development of membrane materials. After the 1970s, DuPont of the United States developed a glass fiber fabric coated with polytetrafluoroethylene (PTEF) as a membrane material, which triggered a rapid development of the membrane structure. [0003] Membrane material is the most important part of the membran...
