Embodiment 1

[0028] A high-efficiency flame-retardant, smoke-suppressing and environmental-friendly dual-functional additive, the specific preparation process is as follows:

[0029] According to the calculation, the total load of molybdenum and zinc is 15% (molar ratio: zinc / molybdenum = 2 / 1), then add a certain mass ratio of zinc borate, ammonium molybdate and nano halloysite carrier, stir at room temperature for 2 hours and then ultrasonically disperse 5 minutes, followed by rotary evaporation at 50°C to remove the solvent, and finally calcined at 250°C for 2 hours to obtain a molybdenum-zinc composite flame retardant and smoke suppressor supported by nano halloysite, which is the high-efficiency flame-retardant, smoke-suppressing and environmental protection dual-function assistant agent. The prepared bifunctional flame retardant and smoke suppressant is ground and sieved for use.

Abstract

The invention discloses an efficient, flame-retardant, smoke-suppressing and environmentally-friendly bifunctional assistant, and a PVC-U material prepared from the same. A preparation technology of the bifunctional assistant comprises the following steps: dissolving a flame-retardant smoke suppressant in water or ammonia water, adding a nano-halloysite carrier, performing uniform mixing at room temperature, removing the solvent, and carrying out high-temperature calcination to obtain the nanohalloysite-loaded flame-retardant smoke suppressant bifunctional assistant. The efficient, flame-retardant and smoke-suppressing bifunctional assistant is provided by using a lead-cadmium-free formula, and the PVC-U material prepared by using the efficient, flame-retardant, smoke-suppressing and environmentally-friendly bifunctional assistant as a flame-retardant smoke suppressant, and has the advantages of high flame-retardant efficiency, low smoke generation amount, very low smoke toxicity, great increase of the escape probability of human beings in fires, no pollution to the environment, and facilitation of ensuring of the life and property safety of the human beings; the preparation technology has the advantages of simplicity, low cost, and convenience in large-scale promotion and application; and additionally, the PVC-U material of the invention fills the gap in the existing market gap, improves the development level of the upstream and downstream industries of the PVC-U material, and has great economic and social significance.

Description

technical field [0001] The invention relates to the technical field of PVC-U plastic materials, and more specifically relates to a high-efficiency flame-retardant, smoke-suppressing and environmental-friendly dual-functional additive and a PVC-U material prepared therefrom. Background technique [0002] PVC is the second largest general-purpose plastic in the world after PE. It has excellent comprehensive physical and chemical properties, chemical corrosion resistance, high strength, excellent insulation performance, long service life, low cost, and has natural properties due to its high chlorine content. Put out the flame retardant performance. Therefore, PVC is widely used in power cables, electronic appliances, automobiles, home furnishing, building materials and other fields. However, as humans have higher and higher requirements on the safety and environmental performance of materials, the PVC-U materials currently available on the market have been difficult to meet th...
