Description

A kind of adhesive for packaging of nano diatomite modification
Technical field
The present invention relates to a kind of sizing agent, be specifically related to a kind of adhesive for packaging of nano diatomite modification.
Background technology
Adhesive for packaging is in the generation of the basis of packaging industry fast development and develops, the performance of adhesive for packaging, quality have directly affected packing effect and quality, present wrapping sizing agent ubiquity thermotolerance is relatively poor, and winter hardiness is not good, and package stability is poor.Relatively poor in order to overcome traditional sizing agent thermotolerance, the shortcoming such as winter hardiness is not good, and package stability is poor by improving prescription, thereby is produced a kind of novel package sizing agent.
Summary of the invention
The purpose of this invention is to provide that a kind of thermal insulation is good, water-tolerant, cohesive strength are high, the adhesive for packaging of the nano diatomite modification of excellent storage stability.
The technical solution used in the present invention is as follows:
A kind of adhesive for packaging of nano diatomite modification, raw material by following weight part is made: vinylbenzene 100-120, ethyl acetate 100-150, chloroprene rubber CR121 20-25, dimethylbenzene 15-20,4,4 '-diphenylmethanediisocyanate 1-2, polyisobutene 8-12,3-aminopropyl trimethoxysilane 2-3, PTMG 2-3, SG-2 type polyvinyl chloride resin 3-5, ferrocene 1-2, epoxy resin modification polyamide hot 10-15, polyvinyl alcohol 8-12, epoxy Toenol 1140 3-5, dioctyl maleate 3-5, sodium bicarbonate 1-2, sulphur 0.5-1, zinc oxide 3-5, Imarcaptoacetate dioctyltin 1-2, nano diatomite 10-15, precipitated silica 10-15, atlapulgite 10-15, sec.-propyl distearyl acyl-oxygen base Aluminate 1-2, irgasfos 168 1-2, anti-aging agent ODA 1-2, anti-aging agent TPPD 1-2, Vulcanization accelerator TMTD 1-2, accelerant CZ 1-2, captax 1-2, modification trees ashes 1-2.
Described modification trees ashes are made by following steps: use first 10-15% salt acid soak trees ashes 3-4h, deionized water wash is clean, soak 3-4h with the 10-12% sodium hydroxide solution again, extremely neutral with deionized water wash again, oven dry adds and is equivalent to the sodium lignosulfonate of trees ashes weight 2-3%, the paregal O of 1-2%, the phthalic ester of 2-3%, the talcum powder of 3-5%, and high speed 1200-1500r/min stirs 1-2h, oven dry, pulverizing grinds to form ultrafine powder and gets final product.
The preparation method of the adhesive for packaging of nano diatomite modification may further comprise the steps:
(1) with chloroprene rubber CR121, dimethylbenzene, 4,4 '-diphenylmethanediisocyanate, polyisobutene, 3-aminopropyl trimethoxysilane, PTMG, SG-2 type polyvinyl chloride resin, ferrocene, epoxy resin modification polyamide hot mix, at 100-120 ℃ of lower reaction 1-2h;
(2) other material is mixed with reactant, stir 30-40min, obtain finished product, packing gets final product.
Beneficial effect of the present invention:
The present invention has improved it at the dispersing uniformity in the sizing agent component by the trees ashes are carried out modification, thereby can obviously improve bonding strength and the water tolerance of sizing agent, and it is low to have a cost, the characteristics that effect is good.The present invention adds nano diatomite sizing agent is carried out modification by to formula adjustment, can obviously improve the performance such as heat-resisting, water-fast, wear-resisting of sizing agent.Sizing agent of the present invention has good thermotolerance, winter hardiness, and cohesive strength is high, water-fast protection against the tide, and excellent storage stability, the feature of environmental protection is good, and result of use is good and convenient.
Embodiment
The present invention is further illustrated below in conjunction with specific embodiment.
