Abstract
The invention provides a fire-swellable plastic, which mainly comprises PVC (polyvinyl chloride) and graphite. The fire-swellable plastic comprises the following components in parts by weight: 100 parts of PVC, 30 to 70 parts of graphite, 1 to 3 parts of cross linking agent, 1 to 6 parts of PVC stabilizer, 0.5 to 3 parts of PVC lubricant, 0 to 150 parts of calcium carbonate, 0 to 20 parts of PVC modifying agent, 0 to 5 parts of PVC processing agent, 0 to 20 parts of fire retardant, and 0 to 12 parts of PVC plasticizer. The plastic is prepared by adopting the following steps of: weighing the materials in the proportion, and putting into a mixer; and uniformly stirring, conveying to a kneading machine, pre-plasticizing at a temperature of between 100 and 150 DEG C, and feeding into a plasticizer. The plasticizer is used for directly extruding and molding the fire-swellable plastic or granulating the fire-swellable plastic. The fire-swellable plastic is arranged on four frames of a door or a window, when a fire disaster and other disasters occur, the plastic is preheated to swell, and has the effects of resisting flame and sealing.
Description
Technical field
The present invention relates to a kind of plastics, especially the fiery expansion plastic of a kind of chance.
Background technology
Plastics are a kind of synthetic macromolecular compound, can freely change body pattern, are social a kind of very common goods now.The advantages such as most plastics chemical stabilization, can corrosion, and impact resistance is good, has the good transparency and wear resistance, and good insulating, thermal conductivity are low, but the shortcoming such as most of plastics also exist poor heat resistance, and coefficient of thermal expansion is large, easy firing.Along with scientific and technological development, increasing plastics enter we mankind's life, in offering convenience to us, also exist a large amount of potential safety hazards.Plastic prod easy firing, can emit obnoxious flavour when burning, once run into fire condition, plastics change a kind of hazardous substance into.
Summary of the invention
The object of the invention is the deficiency in order to solve above-mentioned technology and the chance fire expansion plastic that a kind of fusing point is high is provided.
In order to achieve the above object, the designed one of the present invention is met fiery expansion plastic, it mainly comprises PVC and graphite, and described chance fire expansion plastic is made up of the PVC softening agent of PVC processing aid, 0-20 part fire retardant and 0-12 part of PVC properties-correcting agent, 0-5 part of calcium carbonate, 0-20 part of PVC lubricant, 0-150 part of stablizer, 0.5-3 part for PVC of the linking agent of the graphite of the PVC of 100 parts of weight parts, 30-70 part, 1-3 part, 1-6 part.Described PVC processing aid is a kind of auxiliary agent of the workability that is used for increasing plastics.
PVC stablizer is calcium zinc stabilizer, and PVC lubricant is paraffin.The convenient performance that changes PVC of this structure, and cost is lower.
By PVC, graphite, linking agent, for PVC, stablizer, PVC lubricant, Calciofon, PVC properties-correcting agent, PVC processing aid, fire retardant and PVC softening agent weigh in proportion, put into stirrer, after stirring, be delivered to kneader and it carried out entering extruding machine after preplasticizing at 100-150 DEG C.This process has completed stirring, kneading and the plasticity of material.
Extruding machine is product direct extrusion molding, or product is carried out to granulation processing.This process has facilitated next step processing of product, has increased the selectivity of product treatment.
The chance fire expansion plastic that the present invention obtains, by PVC, graphite, linking agent, PVC stablizer, PVC lubricant, calcium carbonate, PVC properties-correcting agent, PVC processing aid and PVC softening agent mix by a certain percentage, produce a kind of novel plastic, it is high that this plastics have burning-point, meet the feature that fire expands, this novel plastic is arranged on to door, on 4 frames of window, in the time meeting the disasters such as fire, plastics can preheating start to expand, by crack between a door and its frame, window seam place blocks, hinder entering of flame and obnoxious flavour, can reach sealing effectiveness, guarantee that people in room and article are not subject to the impact of fire, improve the safety coefficient in house.Patent of the present invention can be directly by system product fashion into our required finished product by extruding machine, also product can be fashioned into particle by extruding machine, particle is being melted to plasticity again, convenient transport.
