Abstract
The invention relates to 4-methyl-1-pentene-containing flame-retardant heat-resistant plastic which comprises the following ingredients in parts by weight: 40-50 parts of 4-methyl-1-pentene, 30-40 parts of low-density polyethylene, 10-20 parts of 1,5-cyclooctadiene, 10-20 parts of butadiene, 10-20 parts of magnesium hydroxide, 10-20 parts of ethylene glycol, and 10-20 parts of calcium oxide. The prepared 4-methyl-1-pentene-containing plastic is good in flame-retardant and heat-resistant effects.
Description
Technical field
The present invention relates to a kind of flame-proof heat-resistant plastic cement, particularly relate to a kind of flame-proof heat-resistant plastic cement containing 4-methyl-1-pentene.
Background technology
Along with the fast development of all trades and professions, in this process, plastic cement industry have also been obtained rapid advances.Simultaneously the demand of people to plastic cement is more and more extensive, is also more and more higher to the specification of quality of plastic cement simultaneously.Relating to the professional domain of flame-proof heat-resistant plastic cement, and some special dimensions, also be increase to the requirement of flame-proof heat-resistant plastic cement thereupon, have fire-retardant less with plastic cement kind that is heat-resisting effect in the market, therefore developing a kind of plastic cement simultaneously with good flame retardant resistance and thermotolerance has the very large market requirement simultaneously.
Summary of the invention
The technical problem solved: the problem that conventional plastic is fire-retardant and heat-resisting effect is poor.
Technical scheme: the present invention is a kind of flame-proof heat-resistant plastic cement containing 4-methyl-1-pentene, be made up of according to weight ratio following composition: 4-methyl-1-pentene 40 ~ 50 parts, Low Density Polyethylene 30 ~ 40 parts, 1,5-cyclooctadiene 10 ~ 20 parts, divinyl 10 ~ 20 parts, magnesium hydroxide 10 ~ 20 parts, ethylene glycol 10 ~ 20 parts, 10 ~ 20 parts, calcium oxide.At 60 DEG C, dropped in pot body by various composition and allocate, stir, after being heated to 200 DEG C, constant temperature keeps 10h, can obtain the plastic cement with good flame-proof heat-resistant effect after cooling.
Beneficial effect: the flame-proof heat-resistant plastic cement containing 4-methyl-1-pentene prepared, has good flame-retarding characteristic and high-temperature stability.Wherein flame retardant properties can reach V-0 rank, and namely flame extinguished in 30 seconds, has good flame retardant effect.After plastic cement keeps 10h at high temperature is 800 ~ 900 DEG C in addition, the flame-proof heat-resistant plastic cement containing 4-methyl-1-pentene still maintains original proterties, other changes does not occur, has good resistance toheat.
Embodiment
Embodiment 1
First pot body is needed to clean up, the temperature of pot body is adjusted to 60 DEG C, take various composition, 4-methyl-1-pentene is 50kg, join in pot, Low Density Polyethylene 40kg is added again while stirring, add 1,5-cyclooctadiene 20kg again, add divinyl 20kg, add magnesium hydroxide 20kg again, add ethylene glycol 20kg, finally add calcium oxide 20kg, thoroughly stir, to ensure the heating temperatures of pot evenly, to thermostatically heating 10h after 200 DEG C, after cooling, just can obtain the flame-proof heat-resistant plastic cement containing 4-methyl-1-pentene.
Embodiment 2
Working method is with embodiment 1, but it is different to take each composition quality, in the present embodiment, 4-methyl-1-pentene consumption is 40kg, and Low Density Polyethylene consumption is 30kg, 1,5-cyclooctadiene consumption is 10kg, add divinyl consumption 10kg, magnesium hydroxide consumption 10kg, ethylene glycol consumption 10kg, Calcium Oxide Dosage 10kg, finally obtains the flame-proof heat-resistant plastic cement containing 4-methyl-1-pentene.
Embodiment 3
Working method is with embodiment 1, but it is different to take each composition quality, in the present embodiment, 4-methyl-1-pentene consumption is 45kg, and Low Density Polyethylene consumption is 35kg, 1,5-cyclooctadiene consumption is 15kg, add divinyl consumption 15kg, magnesium hydroxide consumption 15kg, ethylene glycol consumption 12kg, Calcium Oxide Dosage 18kg, finally obtains the flame-proof heat-resistant plastic cement containing 4-methyl-1-pentene.
Performance test
The plastic cement obtained in embodiment 1, embodiment 2, embodiment 3 has been carried out high temperature resistant and flame retardant test, and the temperature Example 1 that high temperature resistant test adopts is 850 DEG C, and embodiment 2 is 900 DEG C, and embodiment 3 is 850 DEG C, and the time is 10h.The method standard that flame retardant test is selected is the UL94 standard of Underwriters Laboratories exploitation.Result shows, the phenomenon of thawing or deliquescing does not all occur at the corresponding temperature for embodiment 1, embodiment 2, embodiment 3, maintains original performance, and the flame-proof heat-resistant plastic cement therefore containing 4-methyl-1-pentene has higher resistance toheat.The flame retardant test result of embodiment 1, embodiment 2, embodiment 3 shows simultaneously, and the test grade of three embodiments is V-0 rank, and namely flame extinguished in 30 seconds, has good flame retardant effect.
