Abstract
The invention discloses a flame retardant, low smoke, low temperature resistant and cigarette calcination resistant PVC (polyvinyl chloride) floor which comprises the following components by weight: 100 parts of PVC, 40-60 parts of dioctyl phthalate, 10-15 parts of dioctyl sebacate, 3-5 parts of a stabilizer, 2-3 parts of a lubricant weight, 30-50 parts of magnesium hydroxide, 70-90 parts of aluminum hydroxide, 1-2 parts of a titanate coupling agent and 8-12 parts of zinc borate; the cigarette calcination resistance of the flame retardant, low smoke, low temperature resistant and cigarette calcination resistant PVC is effectively improved, and by addition of the dioctyl sebacate, cold resistance can be increased. The flame retardant, low smoke, low temperature resistant and cigarette calcination resistant PVC has high tensile strength and elongation at break and high hardness and cold resistance.
Description
Technical field
The present invention relates to technical field of floor, specifically a kind of fire-retardant, low cigarette, low temperature resistant, resistance to cigarette calcination PVC floor.
Background technology
Along with the development of China's communication, railway, highway passenger vehicle are constantly weeded out the old and bring forth the new, and also objective floor for automobile are had higher requirement simultaneously.Flexible PVC floor has easily the advantage and being used widely such as mat formation, elegant in appearance, durable in use, cheap.Its advantage: 1, ornamental strong: PVC floor has many especially assortment true to nature attractive in appearance, rich color is gorgeous, cutting splicing is easily simple, can give full play to intention and the imagination, can meet the individual demand of Designers and different user, different decorated styles completely.And no color differnece, fast light photograph, radiationless, is used colour-fast for a long time.2, installation is quick, easy to maintenance: the installation of PVC floor is fast, without sand-cement slurry, after 24 hours, just can use.Easy to clean, maintenance free, is not afraid of the erosion of the chemical substances such as water logging, greasy dirt, diluted acid, alkali, general with wet mop cleaning, time saving and energy saving.Daily maintenance is convenient.3, environmental friendly regenerated: PVC floor is the earth material of unique energy regeneration, for protection our earth natural resources and ecotope, more there is huge meaning.4, be widely used: due to the material of PVC floor uniqueness and superpower performance, be widely used in office, school, hospital, sports center.5, comfortable foot feeling: the top layer of compact structure and the infrastructure of multiple style, be applicable to many local uses.And walk on hard ground material, feel is poor, and pin bone can be ached and damage to long-time walking.6, Environmental Safety: the main raw material that PVC floor is used is polyvinyl chloride resin and aluminium hydroxide, magnesium hydroxide, and they are all the renewable resourcess of environment-protecting asepsis, nontoxic, radiationless.7, wear-resisting, scrape resistant: PVC floor surface has the special transparent wear through high-tech processing of one deck, and its wear-resisting revolution can reach 300000 and turn.The wear-resisting revolution of laminated flooring comparatively wear-resisting in traditional earth material only has 13000 to turn, and good consolidated floor also only has 20000 to turn.Are generally 20-30 in superpower wear-resistant, shock resistance, indeformable, reusable, work-ing life.8, snappiness and superpower shock resistance: PVC floor quality is softer, elasticity is fine, can greatly reduce personnel's the tumble injury of slipping, 9, anti-skidding: the wearing layer of PVC floor surface has special anti-skid, and compare with common earth material, PVC floor feel in the situation that of sticky water is more puckery, more difficult sliding into.Because super anti-skid, thus the public place of having relatively high expectations at public safety as airport, hospital, kindergarten etc. be first-selected floor decorative material.10, fire prevention: PVC floor can reach the fire prevention of B1 level, this is also ground material fp highest standard.Itself can not burn and can stop burning.The smog that high-quality PVC floor produces when passive lighting also can never produce injury to human body, can not produce asphyxiant toxic and harmful.11, waterproof: PVC floor is because main component is plastic cement and calcium carbonate, high glass layer of fibers has guaranteed the stability of its dimensional stabilizing, so it is not naturally water funk, just can not be impaired so long as not long-term immersion, also can because of high humidity, not go mouldy or be subject to temperature and moisture effect and be out of shape.12, applicable underground heat: PVC floor, because water-fast, Heat stability is good, heat conduction are good, is specially adapted to geothermal environment, can guarantee long-term durable and good thermo-efficiency, and guarantees not emit objectionable impurities in the situation that circulation is cold and hot.Therefore but in prior art, owing to wherein containing inflammable softening agent, reduced the oxygen index on PVC floor, also caused its not resistance to cigarette calcination and affect attractive in appearance in application, also brought hidden danger to safety, meanwhile, the PVC floor cold tolerance on market is not good, affects the use on PVC floor.
Summary of the invention
The object of the present invention is to provide a kind of fire-retardant, low cigarette, resistance to cigarette calcination PVC floor.
Object of the present invention can be achieved through the following technical solutions:
Fire-retardant, low cigarette, low temperature resistant, a resistance to cigarette calcination PVC floor, comprise the component of following weight part:
As the present invention, further optimize, comprise the component of following weight part:
As the present invention, further optimize, described stablizer is calcium zinc stabilizer, and described lubricant is No. 15 white oils.
As the present invention, further optimize, comprise the antioxidant 264 of 0.5-1.5 weight part.
As the present invention, further optimize, comprise the antioxidant 264 of 1 weight part.
Preparation technology of the present invention is: claim by weight each feed composition, first in high-speed mixer high speed, mediate, kneading temperature is 85-90 ℃; Then two rollers are plasticated, and the roller temperature of two roller plastics machines is 165-175 ℃; Then mold pressing, vulcanizing press temperature is controlled at 165-175 ℃, and precompressed exhaust pressure is 15MPa, and exhaust is wanted fully, and plasticizing forming pressure is 8MPa, the time is 10-15min; After placing 24h after sample preparation, carry out performance test.
Beneficial effect of the present invention: the present invention adds mineral filler magnesium hydroxide, aluminium hydroxide, aluminium hydroxide and magnesium hydroxide are nontoxic, environmentally friendly inorganic combustion inhibitor, cheap, have fire-retardant, low cigarette, fill function, aluminium hydroxide decomposition temperature is 200 ℃ of left and right, magnesium hydroxide decomposition temperature is 340 ℃ of left and right, therefore by both composite uses, when meeting high temperature or burning, can in wide temperature range, continue to produce dehydration thermo-negative reaction, thereby make material in thermooxidizing decomposition course, keep good flame retardant effect more always, stop lighted cigarette butt to contact with PVC, therefore, can effectively improve the resistance to cigarette burns energy of style, simultaneously, be added with dioctyl sebacate and can increase its cold tolerance.The present invention has higher tensile strength, fault growth rate and higher hardness and winter hardiness.
