Abstract
The invention relates to a low-halogen intumescent flame-retardant resin paste for conveyer belts and a preparation method thereof. The low-halogen intumescent flame-retardant resin paste is prepared by compounding an intumescent flame retardant and a proper synergetic flame retardant and modifying and thinning hydroxides, and has a flame retardant property and chemical properties meeting the requirements of utilization in coal mines.
Description
Technical field
The present invention relates to low halogen expandable flame retardant resin thickener of a kind of used for conveyer belt and preparation method thereof.
Background technology
China is coal production big country, mainly adopts the fire retarding conveying band convey materials, and the consumption of underground conveying belt accounts for the first in the world, and particularly the space, down-hole is narrow and small, has a large amount of flammable explosion gases, and air circulation is poor, and the safety of conveying belt is particularly paid attention to.At present, polyvinyl chloride (PVC) integral core conveying belt is still main means of delivery under the coal mine, this class conveying belt is by adding the very high and very big flame-retardant system of toxic amount of halogen amount, though reach the flame retardant properties requirement substantially, the smog and the toxicity that produce when burning are all very big.Therefore develop low toxicity, the fabric unitary-core flame-resistant conveying belt of low cigarette is an urgent demand that coal mine downhole safety is produced.
Though polyvinyl chloride contains the chlorine atom, decomposes is deviate from hydrogen chloride gas and is brought danger to the staff, and having preferably, mechanical property is to produce overall plastic fire retarding conveying band to be difficult to well be become to stick with paste raw material by other resin alternate with good flame retardancy.Yet traditional paste formula design uses a large amount of halogen-antimony flame-retardant systems all will cause bigger harm to environment in production and use.Guaranteeing under flame retardant properties and the mechanical property equilibrated prerequisite that developing that new flame-retardant system is applied in the conveying belt is main points of the present invention.
Expandable flame retardant system environmental friendliness, good flame retardation effect.It becomes charcoal with foaming and intumescing in intumescent system is in the hot environment such as fire; produce thermoshield; effectively stop and delay the thermal destruction of polymkeric substance; the protection bulk material is avoided the influence of external heat flux; can also stop the effusion of Volatile Gas and the diffusion of oxygen; reduce the transmission of heat and the quick propagation of fire, promoted the one-tenth charcoal, itself reduced combustible volatile simultaneously.Therefore, can improve flame retardant effect from many aspects.That utilizes the expandable flame retardant polymeric acceptor to tie up in the combustion processes to be shown distinctively expand into the fire-retardant material that the charcoal behavior comes the development environment close friend, to reducing having great significance of fire.
When reducing or replacing halogen-antimony fire retardant consumption, must take all factors into consideration the consumption of expanding fire retardant and use and reach fire-retardant requirement with the collocation of synergistic flame retardant.
Summary of the invention
The purpose of this invention is to provide low halogen expandable flame retardant resin thickener of a kind of used for conveyer belt and preparation method thereof.Adopt expansion type flame retardant, cooperates suitable fire retarding synergist and oxyhydroxide is carried out modification and thinning processing obtains low halogen expandable flame retardant resin thickener, make flame retardant properties can satisfy the requirement of colliery use.
The composition and the mass fraction of the low halogen expandable flame retardant resin thickener of a kind of used for conveyer belt of the present invention are:
100 parts of resins
Softening agent 40-75 part
Flame-retardant plasticizer 10-75 part
High thin modification oxyhydroxide 10-40 part
Composite flame-retardant agent 10-60 part
Synergistic flame retardant 5-25 part
Press down fumicants 0.5-10 part
Stablizer 1-3 part
Coupling agent 0.5-3 part
Static inhibitor 1-2 part
Viscosity-depression agent 0.2-2 part
Above-mentioned resin is polyvinyl chloride (PVC);
Above-mentioned softening agent is dioctyl phthalate (DOP) (DOP);
Flame-retardant plasticizer is a kind of of three (2-chloroethyl) phosphoric acid ester (TCEP), triaryl phosphate or their mixture;
High thin modification oxyhydroxide is magnesium hydroxide, aluminium hydroxide or the hydrotalcite after active modification and high thinning processing, and concrete treatment process is that silane coupling agent and oxyhydroxide mix, and after drying and dispersion and fining stir;
Present inorganic fire-retarded system adopts the little oxyhydroxide of order number mostly, and poor with the consistency of system, a large amount of interpolation flame retarding efficiency and the synergistic effect between the fire retardant are poor, and mechanical property also reduces.The present invention considers that from the over-all properties of thickener adopt superfine modified oxyhydroxide filler, the super-refinement of inorganics has improved the dispersiveness in resin; Coupling agent participates in crosslinking reaction in plasticizing process simultaneously, strengthens the effect of oxyhydroxide and resin, reaches fire-retardant and the enhanced effect, the work-ing life that helps improving conveying belt.
The composite flame-retardant agent that the present invention adopts is ammonium polyphosphate, tetramethylolmethane, trimeric cyanamide, triphenylphosphate is a kind of or their mixture.The present invention has replaced the big halogen-antimony flame-retardant system of toxicity hazard with green expandable flame retardant system, has reduced the release of toxic gas, and the expansion charcoal layer that produces in combustion processes simultaneously can fetter toxic gas to sending out diffusion, plays the effect that poison falls in low cigarette.
The synergistic flame retardant that the present invention adopts is silicon-dioxide, zinc borate, zinc oxide or talcous a kind of or their mixture.The adding of synergistic flame retardant further improves the flame-retardant smoke inhibition effect of expanding fire retardant, produces synergistic effect with liquid flame retardant simultaneously, strengthens flame retardant properties and mechanical property.
The preparation method of the low halogen expandable flame retardant resin thickener of used for conveyer belt of the present invention, take by weighing softening agent, flame-retardant plasticizer, high thin modification oxyhydroxide, composite flame-retardant agent, synergistic flame retardant in proportion, press down fumicants, stablizer, coupling agent, static inhibitor, viscosity-depression agent, earlier solid ingredient is placed and mix into finely dispersed solid powder in the pulverizer, again liquid ingredient is placed to mix the back in the homogenizer and add finely dispersed solid powder, progressively add at last and grind to form thickener after resin stirs.
The present invention determines the optimum formula system of low halogen expandable flame retardant resin thickener, and the thickener that obtains is dipped into through plasticizing and had both satisfied low cigarette, flame retardant properties that conveyor belt material requires behind the fabric core band and be both and guaranteed mechanical property to be well positioned to meet service requirements.
