Problems solved by technology

For adsorption-type odor inhibitors, adsorption is a reversible process, especially in high-temperature environments, there is a risk of analysis, so that adsorption-type odor inhibitors cannot fundamentally solve the problem
For reactive odor suppressors, the PVC formula has complex ingredients, and the raw materials used in the production process are various, resulting in many types of components volatilized from the PVC edge banding material, and it is unpredictable, so it is difficult to have suitable reactants. All the volatile components react, and the reactive odorants, reaction products and by-products themselves may have a certain smell

Embodiment 1

[0035] The preparation method of a kind of low-VOC, low-odor environment-friendly PVC edge banding material in the present embodiment comprises the following steps,

[0036] (1) Weigh the following raw materials: PVC resin 590g, stabilizer inorganic carrier 29g, main stabilizer 4g, auxiliary stabilizer 1g, solid plasticizer 59g, filler 30g, processing aid 6g, internal lubricant 3g, 6g of external lubricant. In fact, pure PVC polymers do not have any odor. The odor of PVC resin powder mainly depends on whether the post-treatments such as monomer removal and drying after polymerization can remove the monomer and the auxiliary agent added during the polymerization process. Volatile small molecular substances such as raw materials are removed. These volatile small molecular substances have a relatively large odor. It can be seen from the above-mentioned selected auxiliary raw materials that the auxiliary raw materials in this embodiment are all high melting points and low volatilit...

Embodiment 2

[0052] The preparation method of a kind of low-VOC, low-odor environment-friendly PVC edge banding material in the present embodiment comprises the following steps,

[0053] (1) The raw materials of the following quality are weighed: PVC resin 600g, stabilizer inorganic carrier 30g, main stabilizer 7g, auxiliary stabilizer 5g, solid plasticizer 48g, filler 38g, processing aid 7g, internal lubricant 7g, 7g of external lubricant, wherein the degree of polymerization of the PVC resin is 900-1100, and the mass fraction of volatile matter of the PVC resin is 0.5%. In addition, the odor test of each of the above raw materials reaches level 3.

[0054] (2) Stir and mix the above-mentioned PVC resin, stabilizer inorganic carrier, main stabilizer, auxiliary stabilizer, processing aid, internal lubricant and external lubricant according to the formula amount, and heat up to 105°C while stirring, and the stirring speed Be 2500r / min, obtain the first mixture that mixes homogeneously;

Abstract

The invention relates to the technical field of polyvinyl chloride (PVC) materials, and particularly relates to a low-VOC, low-odor environment-friendly PVC edge sealing strip material and a preparation method thereof. The preparation method comprises the following steps: weighing 80-120 parts of PVC resin, 3-6 parts of a stabilizer inorganic carrier, 0.5-1 part of a main stabilizer, 0.1-0.4 partsof an auxiliary stabilizer, 7-12 parts of a solid plasticizer, 40-55 parts of a filling agent, 0.5-1.5 parts of a processing aid, 0.2-0.7 parts of an internal lubricant and 0.5-1.5 parts of an external lubricant, and then carrying out mixing and granulating. According to the preparation method disclosed by the invention, processing is carried out a lowest temperature as possible in the premise ofguaranteeing uniform plasticizing of the PVC, so that the degradation probability of the PVC is reduced, then the generation of easily decomposed small molecules is reduced, small-molecular substances possibly generated in a processing process are discharged out, and therefore, the prepared PVC edge sealing strip material has the advantages of low VOC, low odor and good strength.

Description

technical field [0001] The invention relates to the technical field of PVC materials, in particular to a low-VOC, low-odor environment-friendly PVC edge banding material and a preparation method thereof. Background technique [0002] The full name of PVC is polyvinyl chloride plastic, which has the characteristics of bright color, corrosion resistance, firmness and durability. When PVC material is used as edge banding, it is easy to apply glue, embossing, printing and other surface modification treatments, and the price is low. These advantages are Other plastics are incomparable. Therefore, PVC edge banding is the most used type of edge banding in furniture decoration and has broad market prospects. [0003] However, PVC is a brittle material and is also sensitive to heat. In the actual processing process, some auxiliary materials such as plasticizers, stabilizers, and lubricants are often added to enhance its heat resistance, toughness and ductility. There are many auxilia...
