A method for covering a roof, the method comprising (i) providing first and second silicone membranes, where the membranes are in the form of rolls; (ii) unrolling the first and second silicone membranes over a roof surface; (iii) positioning first and second membranes adjacent to one another and overlapping and edge of the second over an adjacent edge of the first membrane to thereby form a lap; (iv) securing the first and second membranes to the roof surface; and (v) seaming the first membrane to the second membrane in the lap.

A waste tire resourceful regeneration treatment method is provided, including: step S1, sorting, including: sorting waste tires according to types of the waste tires to obtain target waste tires with steel wires; and step S2, bead-cutting, including: performing a bead-cutting process on the target waste tires through a bead-cutting machine, to cut the target waste tires into beads and first remaining portions separated from the beads. With respect to the method, the target waste wires with steel wires are sorted out from waste wires of different types, a bead-cutting machine is used to remove beads with steel wires from the waste tires with steel wires and separate the steel wires from the beads with steel wires, then a series of processes including cleaning, crushing, magnetic separation, fiber separation, sieving, desulphurizing, and cooling are performed to obtain recycled resources of the waste tires.

A carbamate ester compound represented by the general formula:
ZOCONH(CH.sub.2).sub.nNHCOOZ[I]
wherein Z is [i], [ii], or [iii] below, and n is an integer of 2 to 10, ##STR00001## (wherein R.sup.1 and R.sup.2 are each independently a lower alkyl group having 1 to 5 carbon atoms, R.sup.3 is a hydrogen atom or a lower alkyl group having 1 to 5 carbon atoms, and a is 1 or 2). The carbamate ester compound is used as a vulcanizing agent for carboxyl group-containing acrylic rubber and improves the delay of the vulcanization rate by scorch suppression.

A sealing article includes a body and a coating layer disposed on at least one surface of the body. The body comprises a polymeric elastomer such as perfluoroelastomer or fluoroelastomer.

An algae-elastomer composite including an elastomer matrix; algae; and a mixing additive sufficient to achieve a desired property. The algae can be present in a milled condition having a particle size value of between about 10 and 120 microns. The algae is mixed with the elastomer matrix in a dry condition having a moisture content of below about 10%. A method of preparing the algae-based elastomer composite is provided that includes the steps of: premixing an elastomer matrix; adding an algae filler; adding a mixing additive that includes a plasticizer; forming an elastomer-algae blend by blending the algae and elastomer to a temperature sufficient to be further mixed, wherein the temperature is about 10 C. higher than the temperature sufficient for the elastomer alone; adding and mixing a curing or vulcanizing agent for the elastomer dispersing the elastomer-algae blend; and heating and curing the elastomer-algae blend into a final form.

The present invention relates to a method of preparing reduced graphene oxide, incorporation of the reduced graphene oxide into polyisoprene latex to provide a polyisoprene latex graphene composite and elastomeric articles prepared using the polyisoprene latex-graphene composite. In particular, the reduction of graphene oxide is accomplished without the use of strong reducing agents and organic solvents and incorporation of the reduced graphene oxide into polyisoprene latex is accomplished using room temperature latex mixing method or hot maturation. The resultant composite exhibits good colloid stability and polyisoprene latex films produced from the composite exhibit good mechanical properties with improved ageing resistance.
