Description
Technical field
The present invention relates to a kind of preparation process of balustrade, more particularly to a kind of preparation work of beautiful fire-resisting stair handrail
Skill.
Background technology
Balustrade is the supporting rod of stair railing.Balustrade is classified as by material：Stair macromolecule handrail, stair
Iron skill handrail, stair stainless steel handrail, stair glass handrail, stair solid wood handrail.Also some special balustrades：Stair are sent out
Light handrail.The handrail for being currently used for garden landscape building mostly uses pure wooden armrest, and perishable, the service life is low, and unsightly；Also have
Using the handrail of steel, this handrail is of high cost, cannot insulate, there are security risks；In recent years also have using circular solids wood moulding
Handrail, consumptive material is more, of high cost, and shape is dull, unsightly.But existing balustrade often unified appearance, dull coloring；
In addition, weight is larger, fire protecting performance is also very poor, is badly in need of beautiful, environmental protection, the balustrade of fire resisting.
Polyvinyl chloride (PVC) is one of five big general-purpose plastics, cheap, modified high comprehensive performance, total output
It is only second to polyethylene, it is each to be widely used in industry, agricultural, building, electric, communications and transportation, electric power, telecommunication, packaging etc.
A field.PVC is in yellowish translucent, and glossy, transparency is less than polystyrene higher than polyethylene, polypropylene.PVC is not
Easy firing, intensity are high, weatherability and excellent size stability.PVC has very strong resistance to oxidant, reducing agent and strong acid
Power, but can be corroded by the concentrated sulfuric acid, concentrated nitric acid etc..The shrinking percentage of PVC is relatively low, and generally 0.2% ~ 0.6%.PVC makees in light, heat
Stability under is poor, under high temperature action or through a long time exposure in sunshine, can decompose generation hydrogen chloride, and further automatic
It is catalytically decomposed and changes colour, physical and mechanical property can also decline rapidly, must be added to stabilizer in practical applications to improve to heat
With the stability of light.PVC is difficult to, and because its melting temperature is close to decomposition temperature, and mobility is poor, and processing technology range is very
It is narrow, therefore usually require that other auxiliary agents such as plasticizer, lubricant, processing aid are added.According to the difference of plasticizer consumption, PVC
Product can be divided into soft and two kinds of hard.Hard PVC high mechanical strength, it is durable, for produce structural member, shell, toy,
Plank, tubing etc..
The present invention is intended to provide a kind of preparation process of beauty fire-resisting stair handrail, can produce beauty, and environmental protection, fire resisting
Balustrade.
