Description
Technical Field
The invention belongs to the technical field of new materials, and relates to a 90 ℃ soft polyvinyl chloride elastomer sheath material.
Background
With the appearance and development of high polymer materials, fire accidents are increased continuously, the flame retardant technology of the high polymer materials is developed, the insulation and the sheath of the wire and the cable are made of the high polymer flame retardant materials, and the development of the flame retardant cable technology is promoted through serialization, diversification, performance evaluation and the promotion of flame retardant test standards.
Due to the teaching of cable fire, in recent years, the flame-retardant cable technology has been greatly developed, and the flame-retardant cable has become a necessary trend of cable development, so that the flame retardance of PVC materials and the development of new products are actively promoted.
Polyvinyl chloride (PVC) resin is a general polymer material with large output and excellent comprehensive performance. Since the 1936 time of industrialization. The production is increasing, and so far, the production is second only to polyethylene, and is second. Because the molecular structure of the PVC material contains a large amount of dosage form-Cl groups, the intermolecular force is strong, the product is crisp and hard, PVC is usually used as hard plastic, and a large amount of plasticizer is added to increase the flexibility of the PVC material and reduce the hardness of the product, so that the plasticizing system has the capability of large deformation and rapid recovery deformation at room temperature and has the performance similar to crosslinked rubber. Because of its advantages of low price and simple processing, soft PVC is often used in cable sheath materials.
In order to prepare PVC having low hardness, it is conventional to add a large amount of low molecular weight plasticizer to reduce the hardness and increase the flexibility, but this method reduces the mechanical properties and heat resistance of the material, resulting in reduced elasticity and easy plastic deformation, and the low molecular weight plasticizer migrates with the passage of time, thereby deteriorating the flexibility, aging resistance and durability of the product.
On the premise of not increasing low molecular plasticizer, a proper amount of elastomer is added, so that the flexibility and heat resistance of the product are improved, and the mechanical property of the blend is improved, therefore, the development of the 90 ℃ soft polyvinyl chloride elastomer sheath material is of great significance.
The cable sheath is the indispensable intermediate structure part of cable, plays the effect of protection cable, guarantees the circular telegram safety of cable, lets copper wire and water. Air and other media are isolated, so that the electric leakage phenomenon is avoided. The rubber and polyvinyl chloride composite sheath is widely applied to the fields of mining cables, elevator cables and the like due to good elastic hand feeling, physical and mechanical properties and insulating property. The product has the characteristics of heat resistance, weather resistance, migration resistance, oil resistance, excellent flexibility and the like, and can be widely applied to various fields of elevator cables, mining cables, automobile lines, spring lines, entertainment lines, agricultural lines and the like.
In view of this, through research and development on the 90 ℃ soft polyvinyl chloride elastomer sheath material, the product quality is further improved, the product is gradually promoted to develop towards the middle-high end direction with environmental protection, high performance and high added value, and the influence and the competitiveness of the product in the market, particularly the northern market, are continuously improved.
