Description

Double-deck string and the synthetic floor of plastics

Technical field

The invention belongs to the PVC floor, the floor that particularly double-deck string and plastics are synthetic.

Background technology

Along with the high speed development of science and technology, the Application and Development of new material will become one of emphasis of 21 century China's technical development.In recent years, along with the enhancing of environmental consciousness in the global range and national governments strengthen the safeguard measure to natural environment, make the scientific research personnel have to develop towards material and this direction of environment coordination to the design of material.The natural polymer string more and more causes people's attention as the potential advantages of reinforcing material.See with regard to raw-material utilization and final processing aspect, derive from year growing plants fiber and no matter still all can not cause injurious effects environment as the reinforcing material of thermosetting plastics as the reinforcing material of thermoplastic; The string reinforcing material is compared with conventional plastic filler such as glass fiber French chalk; Have the high and low cost of specific strength, density low (all lower), high tenacity than all inorfils, good thermal property, draw ratio is big, specific area is big, under specific process conditions, also can form advantage such as biodegradation it and the formed composite product of thermoplastic blend have light weight, inexpensive, processability good, the advantages such as little, renewable and degradable to the production equipment wearing and tearing; This is that other any materials are incomparable, thereby has broad application prospects in a lot of fields.The present invention provides a kind of novel double-layer string and plastics synthetic floor, has environmental protection, low cost, high tenacity, good advantages such as thermal property.

Summary of the invention

Goal of the invention

The present invention provides a kind of double-deck string and plastics synthetic floor, environmental protection, low cost, high tenacity, good thermal property.

B, mixing: on two roller plastics processing mills that the PVC plasticizing is even; Temperature is about 140-160;

C, extrude: extrude by foamed plastic extruder and co-extrusion machine pressure after the mixing completion of major ingredient and auxiliary material, wherein about temperature 140-160, pressure 180-200kg/cm ²

D, synthetic double-deck processing typing, warp cooling traction again;

E, finished product.

Beneficial effect

1, the present invention adopts string to replace traditional filler such as kaolin etc.; Because string has natural toughness; Make that the moral floor that generates has excellent toughness and intensity, utilize string and plastic processing production floor simultaneously, utilize the product of PVC/ fiber composite that preferable performance is arranged; Like environmental protection, low cost, high tenacity, good thermal property, can satisfy the quality requirement of certified products.

2, the present invention adopts double-decker, and surface structure adopts the bigger prescription of intensity, has and resistance to wears, characteristics such as resistance to compression.
