A kind of edge banding and its preparation method and application

Abstract

The invention provides an edge sealing strip, a preparation method and application thereof. The edge sealing strip comprises a soft polyvinyl chloride layer and a rigid polyvinyl chloride layer, wherein the preparation raw materials of the soft polyvinyl chloride layer are as follows: In parts by weight, it includes the following components: 100 parts by weight of polyvinyl chloride; 1-7 parts by weight of the first thermal stabilizer; 5-10 parts by weight of elastomers; 0.1-1 parts by weight of PE wax; 20-1 parts by weight of the first plasticizer 40 parts by weight; 20-30 parts by weight of the first filler. The edge sealing strip provided by the invention has a flat plate-like structure, and the structure is simple, and the edge sealing strip can be bent without turning white, and the shrinkage rate is small, thereby achieving an ideal edge sealing effect.

Description

technical field [0001] The invention belongs to the technical field of edge sealing strips, and relates to an edge sealing strip and a preparation method and application thereof. Background technique [0002] The edge band is a material for protecting, decorating and beautifying the section of the furniture board. Its main function is to seal the section of the board to avoid damage to the board by the environment and unfavorable factors during use. Commonly used edge strips are generally divided into log edge strips and traditional polyvinyl chloride (PVC) edge strips. Log edge strips are simple to make but expensive, and their raw materials are mainly derived from the log veneer of trees; In order to protect forest resources and limit the felling of forest trees, the source of raw wood edge strips is limited; for this reason, people think of using PVC instead of log veneer as the main raw material for edge strips; the main component of PVC edge strips is polychlorinated E...

AI Technical Summary

Problems solved by technology

However, the edge banding used in most furniture is hard edge banding, which is a flat structure. When the movable part of the furniture is opened and closed, the collision force is relatively large, which is easy to cause damage to the furniture structure.

[0003] CN103740030A discloses a door and window edge strip material based on thermoplastic elastomer SEBS and a preparation method thereof, which consists of the following raw materials: SEBS rubber resin, polypropylene resin, vulcanizing agent system, antioxidant, light stabilizer and Processing aid, the door and window edge strip material based on thermoplastic elastomer SEBS provided by the invention has the characteristics of halogen-free, high temperature resistance and low compression deformation, but the cost is high and the service life is short

CN201050279Y discloses an edge banding strip, including a hard PVC edge banding strip, two soft PVC edge banding strips are integrally formed on the side of the hard PVC edge banding strip, one of the soft PVC edge banding strips and the hard PVC edge banding strip The edge banding is on the same straight line, and another soft PVC edge banding is stacked on top of the hard PVC edge banding. Short, and its hard PVC is not hard enough, still needs to be improved

Hard edge banding is easy to cause stress and whitening when sealing curved wood boards, and it is easy to produce gaps, which will affect the effect of edge banding. Although soft edge banding does not turn white when bent, but the thermal shrinkage rate is relatively large, it is easy to shrink and affect the edge banding Effect
