Abstract
The invention relates to a formula of a foamed thermoplastic elastomer for overwater dustbins and a preparation process thereof. The formula is characterized by including the thermoplastic elastomer, hydrogenated styrene, butadiene-styrene, ethylene-vinyl acetate copolymer, cosmetic grade white oil, a moderate lubricant, a crosslinking agent and an antioxidant, wherein the weight ratio of the thermoplastic elastomer, white oil and ethylene-vinyl acetate copolymer is 15:25:10. The preparation process is as follows: firstly adding additives into the material, including the lubricant, the crosslinking agent and the antioxidant, mixing to form foamed thermoplastic elastomer particles at the temperature of 180-200 DEG C; mixing and banburying the foamed thermoplastic elastomer particles, the ethylene-vinyl acetate copolymer and modified polyethylene, the crosslinking agent of triallyl cyanurate, the antioxidant and a foaming agent, tabletting, and placing the tablet in a foaming machine to foam to obtain the foamed thermoplastic elastomer. The formula and the process of the present invention have the characteristics of convenient processing, good rebound, good feel, recycling, lower cost than rubber, and saving the cost by about 10-20%.
Description
Technical field
The present invention relates to a kind of prescription and complete processing thereof of foam material, relate in particular to a kind of prescription and complete processing thereof of the foamed thermoplastic elastomers material for rubbish container waterborne.
Background technology
At present, various floating solids rubbish waterborne and various because the algae that Water Eutrophication produces has been caused serious pollution to water quality, this has all caused very large impact to the deterioration of physical environment and people's life, known anti-pollution vessel waterborne also has, but structure is comparatively complicated mostly, cost is higher, and successful spread is not too easy.Therefore expect arranging on the water with ground on similar rubbish container, both be convenient for people to abandoning of rubbish, also be convenient to the cleanup crew simultaneously and concentrate cleaning.
Number of patent application is that 03139293.8 patent has proposed a kind of separation of rubbish and built the method in Overwater floating rubbish shop, and its main contents are: a kind of waste disposal method and rubbish made the method for building Overwater floating rubbish shop.The mode of its realization is: can refuse classification waterborne as standard to swim in, and can be on the water floating rubbish is made the surface floating body itself of building Overwater floating rubbish shop after sterile-processed and reached various members on the buoyancy aid; Can not be on the water floating rubbish is made the member of the rest part of building Overwater floating rubbish shop after sterile-processed.The present invention fills up the blank of existing refuse collection, classification, processing, utilization and publicity, education, utilize the self character of rubbish to be aided with the technology of reprocessing, wide ocean is expanded in the place of garbage utilization, the rubbish shop is become comprehensive, unique, the efficiently refuse treatment that can float on the water and can travel around the world various places utilize method.The certain environmental protection of this idea is unique, considers that still the diversity of rubbish waterborne and recycling rate are low, and the insoluble situation of processing mode, the invention discloses a kind of method that adopts foamed thermoplastic elastomers to make rubbish container waterborne.
Used EPDN foamed products is processed trouble in the market, high cost, and resilience is poor, feel is poor, can not recycle.The foamed thermoplastic elastomers that the present invention adopts can overcome these shortcomings.
Summary of the invention
The purpose of this invention is to provide a kind of modified thermoplastic elastomer foam material, it have easy to process, resilience good, good hand touch, can be recycled, cost is more superior than EPDN 1R rubber, saves the characteristics about cost 10-20%.
In order to achieve the above object, the present invention is by the following technical solutions: foamed thermoplastic is comprised of thermoplastic elastomer hydrogenated styrene, a butadiene-styrene, ethylene-vinyl acetate copolymer, cosmetic grade white oil and an amount of lubricant, linking agent and oxidation inhibitor, and wherein the ratio of weight and number of thermoplastic elastomer, white oil and ethylene-vinyl acetate copolymer is 15: 25:10.
Preparation technology's flow process of foamed thermoplastic elastomers is as follows: the first step is produced the foamed thermoplastic elastomers particle: at first selecting thermoplastic elastomer hydrogenated styrene, a butadiene-styrene (SEBS), ethylene-vinyl acetate copolymer (EVA) is raw material with the cosmetic grade white oil, and the ratio of weight and number of thermoplastic elastomer, white oil and ethylene-vinyl acetate copolymer is 15:25:10; Adding assistant in above-mentioned raw materials again, lubricant, linking agent TAIC, oxidation inhibitor, oxidation inhibitor is selected pentaerythritol tetrathioglycollate (1010), stearic acid, makes its mixing one-tenth foamed thermoplastic elastomers particle under 180-200 ℃ temperature; Second step foaming: with foamed thermoplastic elastomers particle 20-50 part, ethylene-vinyl acetate copolymer 50-80 part and upgrading polyethylene (PE), auxiliary agent linking agent TAIC cyamelide triallyl 5-0.4 part, oxidation inhibitor 0.2-0.5 part, whipping agent 5-20 part are mixed banburying, compressing tablet, then place foaming machine to foam compressing tablet, namely make foamed thermoplastic elastomers.
Employing with prescription and the present invention of making of method have easy to process, resilience good, good hand touch, can be recycled, cost is more superior than EPDN 1R rubber, saves the characteristics about cost 10-20%.
Embodiment
Below the invention will be further described:
