Abstract
The invention discloses a calcium-zinc flame-retarding smoke-suppressing material, a preparation method thereof, a composite flame-retarding smoke-suppressing material, and a preparation method of the composite flame-retarding smoke-suppressing material. The calcium-zinc flame-retarding smoke-suppressing material is obtained by reacting calcium salt with zinc salt according to a mol mass ratio of 3:1-1:3. The composite flame-retarding smoke-suppressing material is prepared by compounding the calcium-zinc flame-retarding smoke-suppressing material with a mixed flame retardant of magnesium hydroxide, magnesium hydroxide, and ammonium polyphosphate according to a mass ratio of 20-30:70-80. For the flame-retarding smoke-suppressing material, inorganic flame retardants instead of conventional organic flame retardants are used, wherein the inorganic flame retardants cooperate with each other and play a function of fire retardation together. The flame-retarding smoke-suppressing material is added in to a plastic product, such as PVC, and has an excellent flame-retarding effect and a function of smoke suppression.
Description
technical field [0001] The invention relates to the technical field of flame-retardant materials, in particular to a calcium-zinc flame-retardant and smoke-suppressing material for PVC with flame-retardant and smoke-suppressing properties. Background technique [0002] Flame retardant is one of the main additives in plastic processing. After adding, it can make plastics flame retardant and self-extinguishing. At present, among the many additives in the plastics industry, the consumption of flame retardants has already ranked second. With the development of the plastics industry, products made of polymer materials have been used in various fields, including construction, daily industrial products, daily consumer products and so on. Of particular importance are construction materials and power materials. The polymers used in these fields mainly include: soft and hard PVC, PE (cross-linked), glass fiber coating materials, etc. In addition to good product performance, the most...
