Do You Know Hot Melt Adhesives For Furniture?
Published on Jan. 17, 2020
Hot melt adhesive for furniture is a kind of adhesive specially used for pasting artificial boards. It is an environmentally friendly, solvent-free thermoplastic adhesive. When the hot melt adhesive is heated to a certain temperature, it changes from a solid state to a molten state. When coated on the surface of a wood-based panel substrate or edge-sealing material, it cools to a solid state and bonds the material and the substrate together. From the late 1970s, hot melt adhesives began to enter the wood industry for edge banding, plywood cores, panel splicing, furniture tenon joining, etc. Early hot melt adhesive equipment mainly depended on the United States, West Germany, Italy and other countries Equipment, with the maturity and stability of hot melt adhesive equipment in China, the selection and use of hot melt adhesive equipment suitable for the specific conditions of various furniture factories can not only improve the quality and grade of furniture, but also improve production efficiency and reduce panel repairs The difficulty of reducing the labor intensity of workers.
Features: 1. Solid content is 100%, and it has gap filling property, which avoids the defects such as deformation, misalignment and shrinkage of the adherend caused by edge curling, bubbles and cracking. Because there is no solvent, the moisture content of the wood has not changed, and there is no danger of fire and poisoning.
2. Fast bonding, glue and bonding interval is not more than a few seconds, saw head and cutting edge can be completed within 24 seconds, no drying time is required, and can be used in a continuous, automated wood bonding line, which greatly improves production Efficiency, saving plant costs.
3. Wide application, suitable for bonding various materials.
4. High grade hot melt glue stick can be used for several times of bonding, that is, the hot-melt glue coated on wood can be re-heated for secondary bonding when it fails to meet the requirements due to cooling and solidification.
Hot melt adhesive is the most widely used type of adhesive in textiles, especially clothing processing. It is widely used for bonding non-woven fabrics, carpet seams, clothing linings, zippers, etc. Hot melt adhesives used in the textile industry must have good bonding strength, excellent softness, and resistance to washing / dry cleaning. In addition, since the fabric is mostly subjected to steam treatment during the setting process, the glue must be resistant to high-temperature steam, and its softening point must be higher than 115 ° C, and the crystallinity must be appropriate to improve the thermal stability of the glue. . For example, a polyamide is used as a matrix, and the lower limit content is 45% (mass fraction). For fiber fabrics with excellent softness, hot melt adhesives are required to have a lower processing viscosity.
① Hot melt adhesive for fabric sticking
Using bonding instead of sewing can greatly reduce the labor intensity of garment manufacturing, and the garments produced are fine, fit and strong. The hot-melt adhesives used for fabric pasting are mainly polyamide, polycase and polyurethane.
② Hot melt adhesive for lining processing
Adhesive interlining is made by uniformly spreading hot melt adhesive on the surface of the fabric. When in use, cut the adhesive interlining into the required shape and size, and heat-pressure adhere the side coated with hot-melt adhesive to the back of other fabric materials (fabrics). It is lined with the inner layer of clothing, as the skeleton of the clothing, which simplifies the processing process and time of the clothing, and makes the clothing light, beautiful, comfortable, conformable, washable, and durable.
Interlining processing generally requires hot melt adhesives to be colorless and odorless, soft in texture, fast bonding, resistant to dry and wet washing, adhesives that cannot affect fabrics, and light resistance. Interlining processing can use a variety of hot-melt adhesives, almost all types of hot-melt adhesives can be used, the most commonly used are ethylene-vinyl acetate (EVA) hot-melt adhesives, polyamide hot-melt adhesives and high-pressure polyethylene (HDPE) heat Melt powder, and hot melt adhesives and processing methods used for different purposes are also different.
③Hot melt glue for carpet: The basic material of hot-melt adhesive for carpet backing is mostly copolymers of ethylene and other olefinic monomers, such as ethylene-ester-acid copolymers and ethylene-acrylate copolymers. Wait. Most of these cases use ethylene. Vinyl acetate copolymer (EvA).
