Problems solved by technology

However, if the amount of filling is too small, the effect cannot be achieved; if the amount of filling is too large, the toughness of the product will decrease significantly, and the material will become brittle. When the edge is sealed, there will be chipping damage, and it will easily expand to the entire board after damage. , affecting the quality of the plate

Abstract

The invention relates to the technical field of PVC edge edge bands, in particular to an anti-shrinkage PVC edge band and a preparation method thereof. The PVC edge band comprises the following raw materials: PVC powder, an inorganic filler, a plasticizer, a thermal reversible crosslinking agent DCPD, a thermal stabilizer, an impact modifier and a lubricant. According to the invention, the thermalreversible crosslinking agent DCPD is added into the formula, so that the product can maintain the thermoplasticity of PVC during high-temperature molding, and can generate low-temperature crosslinking in the cooling process after molding to form a network structure among molecular chains, thereby obtaining high-temperature resistance, stress cracking resistance and creep resistance, and endowingthe product with favorable shrinkage resistance. When leftover materials are recycled, secondary plasticization can be achieved in a high-temperature decrosslinking mode, and recycling is not affected.

Description

technical field [0001] The invention relates to the technical field of PVC edge banding, in particular to an anti-shrinkage PVC edge banding and a preparation method thereof. Background technique [0002] Polymer edge banding is a thermoplastic coil formed by mixing and pressing polymers as the main raw material, adding plasticizers, stabilizers, lubricants, dyes and other additives. Usually, the main function of the edge banding is to seal the section of the board, so as to prevent the board from being damaged by the environment and unfavorable factors (mainly moisture) during use, and to prevent the volatilization of formaldehyde inside the board. [0003] PVC edge banding is a common type of edge banding, and the product will develop in the direction of energy saving, environmental protection, and non-toxic, and become a high-end decorative material. When the conventional PVC edge banding is used, due to its large shrinkage rate, if the material itself undergoes environm...
