Disclosed is a waterproofing membrane that performs well at both high and low temperatures. The waterproofing membrane comprises a carrier support layer and an adhesive layer, wherein the adhesive layer comprises a pressure sensitive bitumen composition comprising bitumen (asphalt), synthetic rubber, high density polyethylene, ground vulcanized crumb rubber and, optionally, a plasticizer. The waterproofing membrane also may optionally include a removable release sheet on the adhesive layer.

The invention relates to a polymer composite material filled with industrial lignin as well as a preparation method and an application thereof. The polymer composite material is characterized in that substances forming the polymer composite material comprise rubber A, lignin and a third constituent, wherein the ratio of the oven dry parts by weight of the substances in the polymer composite material is 100:(10-300):(0-100); the rubber A is natural rubber or synthetic rubber produced by an emulsion polymerization method; the lignin is hydroxymethylation modified lignin produced from alkali lignin or black liquor; in a technical scheme in which the oven dry part by weight of the third constituent is greater than 0, the third constituent is one or the combination of more than two of other rubbers or plastics except the rubber A, or a plasticizer or operating oil, or argil, montmorillonoid, kaolin, kieselguhr or calcium carbonate, or papermaking pulp taking calcium carbonate as a main ingredient, or alkali-preparing waste, namely, white clay; the polymer composite material filled with the industrial lignin is of a block form or a powder form. According to the polymer composite material filled with the industrial lignin as well as the preparation method and the application thereof disclosed by the invention, the manufacturing cost is further decreased, and wastewater generated during the production process is further reduced.

The invention provides a hand held device for removing loose hair strands from at least one of a pet and a fabric which includes a handle member, a hair removal member having a material from a group consisting of natural rubber, synthetic rubber, vinyl, gum and silicone and adhesive for attaching said hair removal member to said handle member. The invention further provides an accessory for a conventional power operated tool or a vacuum cleaner which is usable for removing loose hair strands.

The invention discloses a processing method for preparing modified plastic rubber through utilizing waste plastic and waste rubber. The processing method is characterized by comprising the following technological steps: (1) selecting raw materials, namely by weight percent, respectively selecting 30-40% of waste rubber which is obtained by crushing waste styrene butadiene rubber (SBR) (synthetic rubber which is prepared by polymerizing styrene and butadiene emulsion), 15%-20% of wood meal and 55-60% of industrial waste sand as the raw materials, wherein each 100 kilograms of the raw materials contain 5 kilograms of waste oil and the industrial waste sand contains waste plastic, pulverized fuel ash and calcium carbonate; (2) crushing and grinding; (3) stirring and smelting; (4) melting and mixing; (5) forming; (6) classifying and packaging; (7) forming plate products. The processing method is reasonable and simple in technology, the technological process is greatly shortened, the production cost is lowered, and the yield is increased; the formed particles have smooth surfaces, so that dust production is reduced or eradicated in feeding and mixing processes during the production; the processing method satisfies the requirements of a production technology, is accurate in feeding amount and ratio, generates small deviation and ensures the product quality, and the yield of enterprises is effectively improved.
