Abstract
The invention relates to the field of PVC material flame retardants and in particular relates to a flame retardant smoke suppressant of a PVC (polyvinyl chloride) material, a preparation method and an application of the flame retardant smoke suppressant. The flame retardant smoke suppressant of the PVC material is composed of the following components in parts by weight: 2-15 parts of aluminium hydroxide, 0.5-5 parts of ammonium octamolybdate, 0.5-4 parts of zinc borate, 0.5-5 parts of zinc molybdate, 0.5-4 parts of zinc oxide and 0.01-0.10 part of stearic acid. The flame retardant smoke suppressant has the advantage that the purpose of flame retardant smoke suppression with fewer materials is basically achieved by the synergistic effect among each component of the flame retardant smoke suppressant. In addition, the PVC material adopting the flame retardant smoke suppressant has good flame retardant performance and excellent resistance tobacco control performance so that casualties and property losses can be greatly reduced in a fire accident.
Description
Technical field
The present invention relates to a kind of PVC material flame retardant area, relate in particular to anti-flaming smoke-inhibiting agent of a kind of PVC material and its preparation method and application.
Background technology
Polyvinyl chloride (PVC) is one of five large general-purpose plastics, and it is widely used in every field with its good ratio of performance to price.Along with country carries forward vigorously to mould Dai Gang, to mould generation wood tendency, PVC is able to fast development especially as chemical building material in recent years.But PVC belongs to flame retardant material, but owing to need add softening agent in the course of processing, thereby improved the inflammable degree of PVC, also can produce a large amount of smog during its goods burning, strengthened the harm of fire to people's life, property.Development along with society, people are more and more stricter for material requirements, common PVC material (Chinese invention patent, the patent No.: 200910100375.4) not high because of its flame retardant properties, the reasons such as the burning fuming amount is large progressively withdraw from indoor or public place furred ceiling zone abroad.Therefore the flame-retardant smoke inhibition problem of PVC material becomes a study hotspot in PVC field.
Fire-retardant and smoke-inhibiting type PVC material is through mixing extrusion moulding sheet material (or road surface treatment after can carrying out again) by polyvinyl chloride resin, calcium carbonate, anti-flaming smoke-inhibiting agent and other small powder, this material has the characteristics such as simple installation, assortment are many, sound insulation, heat insulation, corrosion-resistant, comprehensive mechanical property is good, simultaneously, it has overcome fully in the market that there are the defectives such as flame retardant resistance is not high, the burning fuming amount is large in the PVC material.Total institute is known, and anti-flaming smoke-inhibiting agent is little identical with other plastics additives, and the latter perhaps can improve plastics performance, improves plastic processing, perhaps can extend the work-ing life of plastics.But anti-flaming smoke-inhibiting agent adds, and can affect the mechanical property of PVC material, and addition is larger, affects larger.In addition, the part anti-flaming smoke-inhibiting agent is large on the impact of PVC complete processing, must adjust suitable complete processing and could normally produce.Simultaneously, part flame-retardant smoke inhibition products production cost is very high, and the effect that this just requires us should reach fire-retardant, press down cigarette considers that again the comprehensive cost of product can not be too high, selects suitable product, suitable consumption.
Summary of the invention
In order to solve above-mentioned technical problem, first purpose of the present invention is to provide a kind of anti-flaming smoke-inhibiting agent of PVC material, this anti-flaming smoke-inhibiting agent passes through each component synergistic effect each other, has substantially reached the purpose that reaches flame-retardant smoke inhibition with fewer material, and is all up to standard through the check indices.Second purpose of the present invention is to provide the preparation method of above-mentioned anti-flaming smoke-inhibiting agent.The 3rd purpose of the present invention is to provide the PVC material that adopts above-mentioned anti-flaming smoke-inhibiting agent.
In order to realize first above-mentioned purpose, the present invention has adopted following technical scheme:
A kind of anti-flaming smoke-inhibiting agent of PVC material, this anti-flaming smoke-inhibiting agent is made of the component of following weight part:
0.5 ~ 5 part of 2 ~ 15 parts of ammonium octamolybdate of aluminium hydroxide
0.5 ~ 5 part of 0.5 ~ 4 part of zinc molybdate of zinc borate
