Problems solved by technology

However, the above-mentioned substitutes are not flexible enough in winter, which causes problems in physical properties such as cracking, and the printability, cutting properties, and adhesion are poor in post-processing, so additional processing additives are used. There is a cost burden, and the production of the extrusion process and the price of the material itself are expensive, because the high cost will reduce the economic benefit

Embodiment 1

[0129] With 100 parts by weight of polypropylene carbonate resin (Greenpol, SK Energy Company); 5 parts by weight of reinforcing agent and size stabilizer (LG Chemical, PA828), softener (Japan, DAIFATTY-101); 15 parts by weight of covering Force replenisher (Cosmo Chemical, KA100); 2 parts by weight of lubricant (stearic acid and dioctyl terephthalate from Eastman, USA) were put into a Henschel mixer (HanselMixer) for 20 minutes Dry blending was carried out, and the obtained mixture was placed in a 140° C. kneading (compounding) extruder to carry out extrusion pelletization (pellet). Then it is made into a semi-finished sheet through the kneading process (mixing roll and warming roll) and calendering process, and then the decorative sheet is prepared after printing, pulling (primer) and surface treatment processes. (DecorativeSheet) finished product.

Embodiment 2

[0132] Except not using softening agent, all the other are the same as embodiment 1, and its result is as shown in table 1.

[0133] Table 1

[0134]

Embodiment 3

[0136] With the polypropylene carbonate resin (Greenpol, SK energy company) of 100 weight parts; The impact modifier (LG chemical, IM809) of 5 weight parts; Dioctyl diformate) was put into a Henschel mixer and carried out dry mixing for 20 minutes, and the obtained mixture was put into a mixing extruder at 140° C. for extrusion granulation. Then it is made into a sheet semi-finished product through the kneading process (roller mixing and preheating roller mixing) and calendering process, bonded with glass fiber, and then printed, bonded and surface treated to prepare an interior decorative sheet product.

[0137] The physical property measurement results of the prepared transparent and rigid environment-friendly polypropylene carbonate interior decoration sheet product are shown in Table 2 below.

Abstract

The present invention relates to a resin composition for sheets. More specifically, it relates to an environment-friendly poly(alkylene carbonate) resin composition which uses poly(alkylene carbonate) resin as the main material and also includes reinforcing agent, softener, filler and lubricant. The poly(alkylene carbonate) resin is developed by effectively utilizing carbon dioxide, which is the culprit of global warming. It perfectly solves the controversial issue of environmental hazards caused by existing polyvinyl chloride resin products, and at the same time has the same mechanical, thermal and physical properties, processability, printing suitability, embossing and surface treatment as polyvinyl chloride resin products After processing, and excellent fire characteristics and ductility and other characteristics. The biggest disadvantage of thermoplastics emerging as a substitute for existing polyvinyl chloride resin products is the small-scale extrusion production method. Whereas the poly(alkylene carbonate) resin overcomes the disadvantages mentioned above, it is suitable for calender processing in mass production.

Description

technical field [0001] The present invention relates to a resin composition for sheets. More specifically, it relates to an environment-friendly poly(alkylene carbonate) resin composition. It uses poly(alkylene carbonate) resin as the main material, and also includes reinforcing agent, softener, dimensional stabilizer, impact modifier, filler, hiding power extender, blowing agent, foam cell adjustment 3 or more additives in additives, flame retardants, fireproofing agents, antifogging agents and lubricants. The poly(alkylene carbonate) resin is developed by effectively utilizing carbon dioxide, which is the main cause of global warming. Background technique [0002] The polyvinyl chloride material is mainly used in people's living and office spaces. Due to the environmental pollution and harmfulness to the human body caused by it at home and abroad, the Ministry of the Environment and relevant authorities have advised and restricted the use of polyvinyl chloride resin.
