Abstract
The invention discloses a method for producing environmentally digestible plastic by using a silane coupling agent, which belongs to the technical field of environmental protection plastic. The preparation raw materials comprise polyethylene plastic, clay, and the silane coupling agent, by taking 100 parts as a reference, wherein, polyethylene plastic accounts for 60 parts, clay accounts for 39 parts, and the silane coupling agent accounts for 1 part. The method has the beneficial effect that under heat effect of the silane coupling agent, the coupling agent can be decomposed to generate free radical, and generates crosslinking with an alkene polymer, so that bonding of the alkene polymer is promoted, the element is harmless, production cost is low, and bonding degree is high.
Description
Technical field
The present invention relates to environmentally-friendly plastic technical field, be specifically related to a kind of environment-acceptable performance plastics preparation method using silane coupler.
Background technology
The aspects such as plastics are usually used in, formulation analysis, industrial diagnostic, element/ion analysis, purity analysis.Plastic product is widely used in packaging for foodstuff because of its convenience, inexpensive advantage, has statistics display, and in packaging for foodstuff, plastics packed ratio has accounted for more than half.Although relevant regulations and standard are the most issued, but yet suffer from market using harmful additive and the food plastic packing product of reclaimed materials inferior." environment-acceptable plastic additive " refers to add in plastics and plastics can be promoted to assimilate with soil or promote plastics to adapt to the comprehensive treatment mode of the landfill of rubbish, burning, compost or degraded, slows down the analog assistant to ambient pressure.This is a relative concept, macroscopically says that the auxiliary agent that beneficially plastics and environment assimilate broadly falls into this category." environment-acceptable plastic additive " must possess following 3 technology essential factors: does not affect the serviceability of general-purpose plastics after (l) and plastic blend；(2) under the effect of the natural conditions such as environmental key-element light, heat, antibacterial, microorganism, wind, stress and acid, alkali, water or the anthropic factor such as compost and burning, the assimilation degree of general-purpose plastics and environment can be improved；(3) the own environment-acceptable of auxiliary agent.
Present plastics prepare filler material under combustion decomposition, can produce the oxious component being detrimental to health in a large number.
Summary of the invention
It is an object of the invention to provide a kind of environment-acceptable performance plastics preparation method using silane coupler, the silane coupler that it is used is under the action of heat, coupling desk decomposes generation free radical, can crosslink with vinyl polymer, thus promote the bonding of vinyl polymer, element is harmless, and production cost ratio is relatively low, and degree of adhesion is high.
In order to solve the problem existing for background technology, the present invention is by the following technical solutions: its raw material of preparing comprises vinyon, clay, silane coupler, and as a example by 100 parts, wherein vinyon accounts for 60 parts, and clay accounts for 39 parts, and silane coupler accounts for 1 part.
Its preparation process is:
Step one, weighs 1520 appropriate mesh clays in high-speed mixer, stirring and drying at 110 ~ 120 DEG C；
Step 2, adds a certain amount of silane coupler, carries out coupling cladding 8 ~ 10min, then weighs PE resin by CaO (CaCO3): PE=39:60 (mass ratio) and add in high-speed mixer, discharging after mix homogeneously；
Step 3, through double screw extruder extruding pelletization, obtains clay masterbatch；
Step 4, by clay masterbatch and 1% silane coupler mix homogeneously after, be added separately in Blown-film line blowing obtain environment-acceptable PE thin film (thickness: 0.015 scholar 0.001mm)；
Step 5, the control of unit temperature is: 155 ~ 170 DEG C of I district, II 170 ~ 175 DEG C of district, III 175 ~ 180 DEG C of district, 180 ~ 190 DEG C of IV district.
Blowfilm shaping condition according to the Blown-film line described in step 4 is: blow-up ratio is about 1:6, hauling speed about 30m/min, and screw speed is 35-40r/min.
Using after said structure, present invention have the beneficial effect that silane coupler that it is used under the action of heat, coupling desk decomposes and generates free radical, can crosslink with vinyl polymer, thus promote the bonding of vinyl polymer, element is harmless, production cost ratio is relatively low, and degree of adhesion is high.
Detailed description of the invention
