Abstract
The invention relates to methyl 3,3-dimethylacrylate-containing flame-retardant heat-resistant plastic which comprises the following ingredients in parts by weight: 50-60 parts of methyl 3,3-dimethylacrylate, 40-50 parts of cyclobutene, 40-50 parts of polydodecalactam, 10-20 parts of talcum powder, 10-20 parts of ethylene glycol, 10-20 parts of zinc sulfide, and 10-20 parts of propylene. The prepared methyl 3,3-dimethylacrylate-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 that contains 3,3-methyl methacrylate.
Background technology
Along with the development of society, the plastic cement industry has also obtained significant progress thereupon.In evolution, people are increasing to the demand of plastic cement, also are more and more higher to the requirement of plastic cement simultaneously.In the professional domain that relates to the flame-proof heat-resistant plastic cement, the client is day by day to uprise to the requirement of flame-proof heat-resistant shape glue, have simultaneously on the market at present fire-retardant and plastic cement kind heat-resisting effect is less, therefore develop and a kind ofly have simultaneously good flame retardant resistance and stable on heating plastic cement has boundless market outlook.
Summary of the invention
The technical problem that solves: the fire-retardant and relatively poor problem of heat-resisting effect of conventional plastic cement.
Technical scheme: the present invention a kind ofly contains 3, the flame-proof heat-resistant plastic cement of 3-methyl methacrylate, formed according to weight ratio by following composition: 50～60 parts of 3,3-methyl methacrylates, 40～50 parts of cyclobutenes, 40～50 parts of nylon 12s, 10～20 parts of talcum powder, 10～20 parts of ethylene glycol, 10～20 parts in zinc sulphide, 10～20 parts of propylene.Under 70 ℃, various compositions are dropped into the reactor allotment, stir, be heated to 200 ℃ and keep 10h, the plastic cement that can obtain to have good flame-proof heat-resistant effect after the cooling.
Beneficial effect: after preparing the flame-proof heat-resistant plastic cement that contains 3,3-methyl methacrylate, its flame retardant resistance and high thermal resistance are tested.The flame-proof heat-resistant plastic cement that contains 3,3-methyl methacrylate that the present invention makes, fire-retardant rank can reach the V-1 rank, has good flame retardant effect, and has good heat-resistant quality.
Embodiment
Contain 3, the flame-proof heat-resistant plastic cement preparation method of 3-methyl methacrylate is as follows: get 3,3-methyl methacrylate, 50～60kg, cyclobutene 40～50kg, nylon 12 40～50kg, talcum powder 10～20kg, ethylene glycol 10～20kg, zinc sulphide 10～20kg, propylene 10～20kg.Under 70 ℃, with allocating in the various compositions input reactors, stir, be heated to 200 ℃ and keep 10h, can obtain to contain the plastic cement that 3,3-methyl methacrylate has good flame-proof heat-resistant effect after the cooling.Table 1 is the composition weight proportion of embodiment 1, embodiment 2, embodiment 3.

Embodiment 1
Under 70 ℃, the composition of the described embodiment 1 of table 1 dropped in the reactor according to weight allocate, stir, be heated to 200 ℃ and keep 10h, the plastic cement that can obtain to have good fire-retardant acid and alkali-resistance effect after the cooling.This plastic cement is carried out the flame retardant resistance test, and testing standard is the UL94 standard, and the flame retardant resistance test result is the V-1 rank, has good flame retardant effect.Plastic cement is 700 ℃ of lower 15h of maintenance in scorching hot temperature in addition, contains 3, and the flame-proof heat-resistant plastic cement of 3-methyl methacrylate produces without any unusual phenomenon, has good flame-proof heat-resistant characteristic.
Embodiment 2
Preparation plastic cement method and performance test methods are with embodiment 1, and difference is component content embodiment 2 preparations as shown in table 1, and temperature is 800 ℃ of lower 15h of maintenance when measuring thermotolerance.The result shows that the finished product flame retardant properties test result is all the V-1 rank, has good flame retardant effect.Other variations do not occur in plastic cement behind 800 ℃ of lower maintenance 15h, have still kept original performance and outward appearance.
Embodiment 3
Preparation plastic cement method and performance test methods are with embodiment 1, and difference is component content embodiment 3 preparations as shown in table 1, and temperature is 750 ℃ of lower 15h of maintenance when measuring thermotolerance.The result shows that the plastic cement flame retardant properties test result that contains 3,3-methyl methacrylate is all the V-1 rank, has good flame retardant effect.Other variations do not occur in plastic cement quality and outward appearance behind 750 ℃ of lower maintenance 15h, have kept original performance.
