Description
Technical field
The present invention relates to a kind of PVC adhesive plasters, and in particular to a kind of ship Fire-proofing Fabric and preparation method thereof.
Background technology
With the rise of Chinese vessel industry, ship inner compartment decoration new technology is all to use PVC decorative Film clad steel plate,
But because once fire occurs on ship, its escape is extremely difficult, so SOLAS<<International Convention for the Safety of Life at Sea>>In
It is required that the fire resistance of PVC film will meet the requirement of the low burn property broadcast, and its fire retardancy test will pass through International Maritime Organization<<2010
International fire resistance test application rule>>Part5 is tested.
Although PVC has good fire resistance in itself, a large amount of plasticizer are with the addition of in existing PVC product, are caused
PVC product is easily burnt, and when PVC product is burnt can produce a large amount of smog, for this problem Application No.
A kind of flame-proof PVC artificial leather and its preparation process are mentioned in 201410192430.8, finds that it still has following deficiency through analysis
Part:1. plasticizer DOP has played very big impetus to the burning of PVC in itself, plasticizer DOP, DBP dosages are set in this formula
45 ~ 75 parts fixed, plasticizer consumption is excessive, must add a large amount of fire-retardant modification agents to make up this defect;2. the PVC powder of the degree of polymerization 1800
Processing temperature is higher, is not suitable for foaming product processing, easily foams in advance if temperature is excessive during actual production, there are larger safety
Hidden danger;3. a large amount of fire-retardant modification agents of addition, total addition level have exceeded the amount of PVC, cost is higher;4. blended it is a variety of it is fire-retardant into
Part, and dosage is larger, these compositions are not as that calcium carbonate is so good, and processing is extremely difficult with PVC compatibility, product gelatinization, respectively
The stock dispersion uniformity, product surface presentation quality are difficult to ensure that;5. fire-retardant modification agent dosage is larger, PVC systems can be seriously affected
The physical property intensity of product, limits its use scope;6. it adds 20 ~ 30 parts of antimony oxide in being formulated, and has research to think, and three
Saturation can be reached more than its flame retardant effect after 8PHR by aoxidizing two antimony dosages, be further added by dosage and do not had too big flame retardant effect substantially,
The increase of smoke amount can conversely be caused;7. zinc borate and phosphate and aluminium hydroxide share can effective flame-retardant smoke inhibition, it is but actual
Dosage, which reaches about 20 parts or so, can cause color change in PVC product process, and processability is unstable.
The content of the invention
Goal of the invention:The purpose of the invention is to make up the deficiencies in the prior art, meeting client's items quality requirement
On the premise of limit the dosage of plasticizer, greatly control the facilitation that plasticizer burns PVC, while to processing work
Skill is adjusted, and takes into account each side such as formulation cost, processing stability, product appearance quality, the physical property of product intensity, flame-proof smoke-suppressing
Face factor, there is provided one kind plasticizing is excellent, and appearance uniform is smooth, meets the ship of the flame retardant test requirement of Far East fire prevention inspection center
Use Fire-proofing Fabric.
