Abstract
The invention relates to novel application of chloridized modified waste rubber powder as flame retardant for high polymer, and belongs to the field of waste rubber resource utilization. The chloridized rubber powder as the flame retardant for the high polymer is not yet reported at present. The application comprises the following steps: firstly preparing the chloridized rubber powder of which chloridized degree is more than 30 percent, then adding the high polymer (such as polythene, polypropylene, ABS, synthetic rubber and the like) into the chloridized rubber powder, adding montmorilloniteinto the mixture after the high polymer is evenly plasticized, fully dispersing the montmorillonite in the high polymer, then adding dispersed mixture of chloridized rubber powder, antimony trioxide,stearic acid, aminopropyl trimethoxy silane and stabilizing agent lead sulfate tribasic into the mixture, and continuously mixing the mixture for a plurality of minutes to obtain the flame retardant for the high polymer. Through optimizing formulation, a flame-retardant material of the high polymer/chloridized rubber powder of which limited oxygen index is more than 27 and flame-retardant grade is UL94-V0 can be prepared, so a new path for utilization of the rubber powder is found.
Description
Technical field
The present invention relates to how to realize the novel method of the recycling of shoddy.It is characterized in that adopting water phase suspension or chlorination by solid state method to prepare the chlorination rubber powder, the chlorination rubber powder for preparing is used as the fire retardant of common inflammable superpolymer.
Background technology
In recent years, the bulk deposition of damaged tire and waste have caused a series of global environment and public safety problem, therefore, effectively reclaim and utilize damaged tire to become the task of top priority.At present, handle and utilize the method for damaged tire to mainly contain two kinds: burning and blend.Wherein the method for burning is eliminated gradually because discharging a large amount of pernicious gases.The method that damaged tire is made behind the rubber powder with polymer blending becomes main flow.As everyone knows, the paraffin of high chlorination degree (CP-70) is the polymer flame retardant of using always, and waste rubber powder itself has certain mechanical strength as a kind of polymer composites, and the product after its chlorination has flame retardant properties.Therefore, the rubber powder after chlorination modified can be used as a kind of efficient flame-retarding agent with super quality and competitive price of polymers function.
Summary of the invention
The new purposes that the purpose of this invention is to provide a kind of waste rubber powder namely utilizes chlorination modified rubber powder as the fire retardant of Common Polymers.
The present invention relates to the new purposes of a kind of modified waste rubber powder, it is characterized in that, may further comprise the steps as high polymer flame retardant:
1) the preparation chlorination degree is at the chlorination rubber powder more than 30%;
2) preparation superpolymer/chlorination rubber powder blend;
After high polymer plasticizing evenly, add imvite, imvite and high polymer mass ratio are 1-5: 100; After imvite was fully disperseed in high polymer, adding in advance, scattered and high polymer mass ratio were 32-60: 100 chlorination rubber powder, with the high polymer mass ratio be 24-40: 100 antimony oxide, with the high polymer mass ratio be 1: 100 stearic acid, with the high polymer mass ratio be 0-3: 100 stabilizing agent lead sulfate tribasic and with the high polymer mass ratio be that the blend of 0.8: 100 TSL 8330 continues mixingly can make the high polymeric fire-retardant material.
Superpolymer can be but be not limited to combustible polymers such as polyethylene, polypropylene, ABS, polystyrene, rubber.
Further also in step 2) in blend in to add with the high polymer mass ratio be 3: 100 stabilizing agent lead sulfate tribasic.
The present invention can prepare limiting oxygen index(LOI) more than 27 by optimization of C, and fire-retardant rank is the superpolymer/chlorination rubber powder fire retardant material of UL94-V0 level, and this has found a new approach for the utilization of rubber powder.
