Problems solved by technology

However, in this application, due to the weak force between the air-lifting agent and the porous polymer, it is very easy to volatilize, the active ingredients are seriously dissipated, and the storage and transportation conditions are harsh and not durable, so better use effects cannot be obtained.

Embodiment

[0033] A preparation method for removing the odor of modified plastics masterbatch, comprising the following steps:

[0034] Step 1: Prepare raw materials: 10-35 parts of melamine resin, 1-20 parts of polyether polyol, 1-10 parts of interface treatment agent, 50-85 parts of odor remover, 0.5-2.0 parts of auxiliary agent;

[0035] Step 2: Fully mix melamine resin, polyether polyol, interface modifier, and additives to form a mixture, and then pass air into the mixture while continuously stirring rapidly to obtain a density of 1-20kg / m 3 foam carrier, preferably with a density of 2kg / m 3 , and crush it into 5-100 mesh particles, the preferred particle size is 10 mesh;

[0036] Step 3: Mix the granules in step 2 with the odor remover in a kettle-type container, fully absorb them, and prepare the odor remover masterbatch.

[0037] The melamine resin is water-soluble melamine resin.

[0038] The polyether polyols are oligomers containing ether bonds in the main chain and more th...

Abstract

The invention discloses a modified plastic odor removal master batch and a preparation method thereof and belongs to the technical field of materials. The modified plastic odor removal master batch comprises the following components in parts by weight: 10-35 parts of melamine resin, 1-20 parts of polyether polyol, 50-85 parts of an odor remover, 1-10 parts of an interfacial modifier and 0.5-2.0 parts of an auxiliary. The invention discloses the preparation method. The modified plastic odor removal master batch disclosed by the invention interacts with volatile components, which generate odor in the material, in a modified plastic processing process, the mixture is extracted out of the modified polymer melt by using vacuum negative pressure at a vacuum opening of an extruder, the content ofharmful volatile components such as modified plastic odor molecules is recued and the increasing non-toxic, odorless and harmless requirements for modified plastic products are met.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a modified plastic odor-removing masterbatch and a preparation method thereof. Background technique [0002] At present, modified plastics are more and more widely used in industries such as automobiles, home appliances, IT, agriculture, construction, electronics and electrical, light industry and military industry, and their role is becoming more and more important. On the other hand, when manufacturers of modified plastics produce certain low-odor modified plastics, the smell of the products is often too large during testing, especially the modified products of recycled plastics, due to oxidative degradation, the material has a strong acidic smell, which is more Unable to pass the test; when encountering this kind of problem, manufacturers generally choose high-purity imported materials for raw materials, which increases production costs and reduces product competitiveness; or ...
