Embodiment 1

[0027] (1) Dry 100 g of PVC resin and 5 g of ANP / RGO in a blast oven at 100 °C for 1 hour.

[0028] The invention obtains the hybrid material (ANP / RGO) of ammonium nickel phosphate and reduced graphene oxide through a one-step solvothermal method. The specific experimental steps are as follows: First, 50 mL of ethylene glycol was added to 50 mL of concentrated ammonia water and stirred mechanically for 10 min to form a uniform solution. Then, ultrasonically exfoliated graphene oxide (GO) (50 mL, 0.08 g), sodium dodecylsulfonate (10 mL, 0.75 g), anhydrous potassium carbonate (25 mL, 1 M), dipotassium hydrogen phosphate (37.5 mL, 1 M) and nickel nitrate hexahydrate (25 mL, 1 M) were slowly added to the above homogeneous solution one by one, and kept stirring for 1 h until the mixed solution turned bright blue . Subsequently, the mixed solution was transferred to a 500 mL reactor and heated at 170 °C for 12 h. Finally, the reactor was cooled to room temperature, the precipitat...

Embodiment 2

[0041] Same as Example 1, except that the flame retardant is 10 g of ANP / RGO, that is, 100 g of PVC resin and 10 g of ANP / RGO in step (1).

Embodiment 3

[0043] Same as Example 1, except that the flame retardant is 15 g of ANP / RGO, that is, 100 g of PVC resin and 15 g of ANP / RGO in step (1).

Abstract

The invention provides a flame-retardant PVC cable material and a production method thereof. The flame-retardant PVC cable material is composed of the following components of, in parts by weight, 100parts of PVC resin, 5-15 parts of flame retardant, 40 parts of plasticizer, 1 part of coupling agent, 3 parts of stabilizer and 1 part of lubricant; and the flame retardant is a hybrid material of ANPand RGO. The hybrid material ANP/RGO of the ANP and the RGO is designed and synthesized to make a polyvinyl chloride material flame-retardant and to plastify the polyvinyl chloride material, the ANP/RGO has the advantages of being high in thermal-insulating and oxygen-insulating capability, good in thermal stability and good in dispersity, the flame retardant and smoke suppression efficiency andthe mechanical performance of the PVC cable material can be improved, and the problems that a traditional inorganic flame retardant is large in adding amount and low in flame retardant and smoke suppression efficiency, worsens the mechanical performance of a material, and the like are solved. The ANP/RGO is green and non-toxic, raw materials are easy to obtain, preparation is easy, and by adding the ANP/RGO into PVC, the flame-retardant PVC cable material has large market potential and study values.

Description

technical field [0001] The invention relates to the technical field of preparation and application of chemical flame-retardant materials, in particular to a flame-retardant PVC cable material and a preparation method thereof. Background technique [0002] Traditional inorganic flame retardants include nitrogen-based flame retardants, phosphorus-based flame retardants, magnesium-aluminum-based flame retardants, transition metal oxides, and the like. The nitrogen-based flame retardants that have been used so far are mainly triazine compounds, namely melamine and its salts, which are colorless, halogen-free, low-toxic, low-smoke, and cheap. The main disadvantage is that the flame retardant efficiency is not good, and the compatibility with thermoplastic polymers is not good, which is not conducive to dispersing in the flame retardant substrate. The most important varieties of inorganic phosphorus-based flame retardants are red phosphorus and ammonium polyphosphate, which have ...
