Abstract
The invention provides a butyl rubber sealing adhesive tape and a preparation method thereof, which belong to the technical fields of sealing adhesive tapes and preparation thereof. The butyl rubber sealing adhesive tape and the preparation method thereof are characterized in that: butyl rubber and the like serve as basic materials and waste leather meal serves as a filling reinforcer; and the preparation method comprises the steps of mixing repeatedly, kneading, performing extrusion moulding, cutting into blocks and packaging the finish product by using release paper. The product has readily available raw materials, low cost, simple manufacturing process and performance index reaching or exceeding that of the conventional like product; and the product uses the waste leather meal as the raw material, which belongs to resource recycling of wastes, and has obvious environmental ecological and social benefits.
Description
Technical field
The invention belongs to sealant tape and preparing technical field thereof, relate to simultaneously the technological method of the renewable resource utilization of discarded leather powder.
Background technology
Isoprene-isobutylene rubber has good resistance to air loss and good cementability, the characteristic such as low temperature resistant, ageing-resistant, and is widely used in the aspects such as waterproofing and airtight, damping adhering and sealing., material of construction adhering and sealing waterproof bonding such as cultural goods, machinery equipment damping adhering and sealing, material joints are airtight bonding etc., generally believe it is easy to use, of many uses, safe and reliable, the economical and practical adhering and sealing material of a class.
Usually, take isoprene-isobutylene rubber as main preparation unvulcanised sealant tape, need to add strengthening agent carbon black and a large amount of organic solvent, environmental pollution can not be ignored in the use procedure.For this reason, Chinese invention patent ZL00123581.8 provides a kind of colour, high-performance, pressure sensitive isoprene-isobutylene rubber sealing jointing tape, adopts nanometer and accurate nano silicon to do the scheme of strengthening agent.
In addition, the process hides output of China has accounted for about 23% of the whole world, and leather is again the main industries of light industry outlet.In leather manufacture, the process hides utilization ratio of animal skin is less than 90%, and the collagen more than 10% is discarded as the corner tankage.Disregard the leatherware of discarded shabby damage, only have approximately 200,000 tons (butt) discarded Animal Skin Collagen resource to wait to utilize every year in the leather production, and the waste total amount is considerable.Yet, utilize technology around the renewable resource of discarded leather, still be in the junior stage; People pursue the harmony of resource and environment, realize that conservation-minded society's target of Mode of Circular shoulders heavy responsibilities.
Summary of the invention
Main purpose of the present invention provides a kind of butyl rubber sealing adhesive tape and preparation method thereof.
For realizing the technical scheme of main purpose of the present invention: take discarded leather powder as filling toughener, maleic anhydride is auxiliary agent, preparation high strength non-vulcanization type butyl rubber sealing adhesive tape.
Butyl rubber sealing adhesive tape of the present invention is comprised of and deal (by weight) forms: isoprene-isobutylene rubber 10-15 part, leather powder 2-10 part, polyisobutene 10-18 part, light calcium carbonate 45-60 part, precipitated silica 3-8 part, softening agent 3-8 part, tinting material 3-8 part, maleic anhydride 0.1-3 part and anti-aging agent 1-3 part following raw material.
Leather powder of the present invention is from the subcutaneous pin waste material of the chrome tanning pig, cattle and sheep of tannery, and chrome content is less than 5%, and being ground into granularity is 40-400 purpose powder.
Softening agent of the present invention comprises coumarone indene resin, naphthenic oil, dioctyl phthalate (DOP) a kind of or more than one materials wherein.
Tinting material of the present invention comprises carbon black, cyanogen orchid, iron oxide red, permanent yellow, red a kind of or more than one materials wherein of plastics.
Anti-aging agent of the present invention comprises antioxidant MB, chemistry Mercaptophenylimidazole by name; Or anti-aging agent RD, chemistry 2,2,4 trimethylammoniums, 1,2 dihyaroquinoline polymkeric substance by name; Or both mixtures.
The preparation method of butyl rubber sealing adhesive tape of the present invention is as follows: that each forms through described deal is mixing for described butyl rubber sealing adhesive tape, kneading, extrusion moulding, cut into strip and block, interleaving paper packaging final prod.
Positively effect of the present invention is: utilize tannery's chrome shaving, leftover bits etc., it is ground into granularity is 40-400 purpose leather powder, as the filling toughener of butyl rubber sealing adhesive tape composition, and obtain higher, the lower-cost sealant tape product of intensity.Not only product performance index reaches and surpasses existing like product index, and to use discarded leather powder be raw material, belongs to the regeneration of changing rejected material to useful resource, and its environmental ecology and social benefit are obvious.
