Problems solved by technology

Although some corrugated cardboard boxes with heat insulation effect have appeared at present, the method is to fill some filling materials in the carton. The filling materials generally use materials with light weight. Poor, and not suitable for packaging and transportation of some perishable food; while some cartons are equipped with heat insulation layer, the setting of heat insulation layer will increase the weight of the carton, because corrugated cardboard boxes have fixed edge pressure strength and burst resistance Strength, when the weight of corrugated cartons increases, the amount that can be packed must be relatively reduced, otherwise it is easy to damage the carton and it is not easy to protect the product

Abstract

The invention provides a heat-insulation and heat-preservation environment-friendly corrugated board and a preparation technology thereof. The heat-insulation and heat-preservation environment-friendly corrugated board takes acrylate resin as a main material, auxiliary materials including dimer acid, zircon sand powder, isopropyl alcohol and the like are added, and a stabilizing agent and an initiator are added to enhance the mixing effect; in a preparation process, all the raw materials are added in sequence to prepare a No. 1 material to a No. 4 material, so as to ensure that all componentscan be sufficiently mixed to react, and the synergetic effect is realized; the performance of a special adhesive is greatly improved; a whole technological process is environmentally friendly, has nopollution and has relatively low cost; a heat-preservation layer is arranged so that the stuck corrugated board has excellent heat-insulation and heat-preservation effects and also can have excellentedgewise compression strength and bursting strength, and the bearing capability of a corrugated board box can be improved; compared with the prior art, the corrugated board provided by the invention has the advantage of good heat-insulation and heat-preservation effects and can meet package protection requirements of almost products.

Description

technical field [0001] The invention relates to the field of corrugated cardboard, in particular to a heat-insulating and heat-preserving environment-friendly corrugated cardboard and a preparation process thereof. Background technique [0002] Because of its light weight, low cost, easy processing, and convenient storage and transportation, corrugated boxes have become important transportation packaging containers, and are widely used in food, beverages, household appliances, medicine, daily necessities and other products. [0003] In the transportation process of some products, such as seafood and vegetables, due to the lack of refrigeration and heat preservation conditions, product deterioration is easy to occur. For example, some products are sent by express, and the products are often required to be kept in a frozen state. For transportation, if ordinary express packaging boxes are used, the product will deteriorate before it reaches the destination. At this time, if th...
