preparation example Construction

[0020] The preparation method of insulating tape provided by the invention comprises the following steps:

[0021] Preparation of insulating tape:

[0022] Such as figure 1 As shown in step S101, the polyester polyol oxygen, flame retardant, talcum powder and carbon black are mixed to obtain a resin mixture, specifically, according to the number of parts by mass, 80-120 parts of polyester polyol oxygen , 5-20 parts of flame retardant, 10-50 parts of talcum powder and 10-200 parts of carbon black are added to the kneader respectively, and kneaded for 10-30 minutes to obtain the resin mixture; preferably, according to parts by mass In counting, 100 parts of polyester polyol oxygen, 10 parts of flame retardant, 30 parts of talcum powder and 100 parts of carbon black were added to the kneader respectively, and kneaded for 20 minutes to obtain the resin mixture; wherein, Polyester Polyol Oxygen C 4 -C 30 Polyester polyol oxygen. The flame retardant is selected from antimony tr...

Embodiment 1

[0027] 1) Add commercially available polysiloxane acrylate, magnesium hydroxide flame retardant, talcum powder and carbon black to the kneader, wherein the mass ratio: polysiloxane acrylate is 100 parts, magnesium hydroxide flame retardant 5 parts of agent, 10 parts of talcum powder, and 10 parts of carbon black were kneaded for 15 minutes to obtain a resin mixture.

[0028] 2) Add an isocyanate curing agent into the resin mixture, 100 parts of the resin mixture, 5 parts of the isocyanate curing agent to obtain the final product.

[0029] 3) The final product is calendered into coils of corresponding thickness with a calender, coated with PET film on both sides, sliced, and vacuum-packed with aluminum-coated packaging to obtain the final product.

[0030] 4) Test the hardness, breakdown voltage, UV accelerated aging performance, flame retardancy and waterproof performance after curing.

Embodiment 2

[0032] 1) Add commercially available adipic acid polyester diol, antimony trioxide flame retardant, talcum powder and carbon black, etc. into the kneader, wherein the mass ratio: adipic acid polyester diol is 120 parts, trioxide 20 parts of diantimony flame retardant, 50 parts of talcum powder, and 150 parts of carbon black were kneaded for 30 minutes to obtain a resin mixture.

[0033] 2) Add phenolsulfonic acid curing agent to the resin mixture, 100 parts of the resin mixture, 50 parts of the isocyanate curing agent to obtain the final product.

[0034] 3) The final product is calendered into coils of corresponding thickness with a calender, coated with PET film on both sides, sliced, and vacuum-packed with aluminum-coated packaging to obtain the final product.

[0035] 4) Test the hardness, breakdown voltage, UV accelerated aging performance, flame retardancy and waterproof performance after curing.

Abstract

Embodiments of the invention provide a preparation method of an insulating tape. The method includes the following steps: mixing polyester polyol oxygen, a flame retardant, talc powder, and carbon black to obtain a resin mixture; adding a curing agent to the resin mixture to obtain a cured resin mixture; calendering the cured resin mixture into a coiled material; and attaching PET film to upper and lower sides of the coiled material and slicing to obtain the insulating tape. The insulating tape prepared by the method can be used for insulation protection in fields of high-voltage electricity and electric appliances, can achieve protection of water proofing, insulation and voltage breakdown resistance, is simple in construction, and can achieve long-term protection.

Description

technical field [0001] The present invention relates to the technical field of materials, and more specifically, to an insulating adhesive tape. Background technique [0002] Insulating tape is a kind of tape used to prevent electric leakage and play an insulating role. It consists of a base tape and a pressure-sensitive adhesive layer. The base belt is generally made of cotton cloth, synthetic fiber fabric and plastic film, etc., and the adhesive layer is made of rubber and tackifying resin and other compounding agents. The preparation method mostly adopts the method of coating, which requires on-site ingredients during construction, and several brushing processes are required, the operation is complicated, and the performance is highly dependent on the construction process. Contents of the invention [0003] In order to solve the problems existing in the prior art, according to one aspect of the present invention, a kind of preparation method of insulating tape is provi...
