A method of making honeycomb cardboard with corrugated paper

Abstract

The invention discloses a method of manufacturing a honeycomb paperboard through corrugated paper. The method of manufacturing the honeycomb paperboard through the corrugated paper comprises the steps of uncoiling, pre-treatment of raw materials, drying, recoiling, manufacturing of a honeycomb paper core and forming of the honeycomb paperboard. After pre-treated, the raw materials of the honeycomb paperboard are applied to a normal production process of the honeycomb paperboard. The manufactured honeycomb paperboard is good in performance, due to the fact that the corrugated paper serves as raw paper, the honeycomb paperboard is easy to degrade, nontoxic, harmless and free of pollution, and has the advantages of being light in weight, shockproof, heat-insulated, sound-insulated, inflaming-retarding, moisture-proof and the like, thereby being capable of being widely applied to the construction industry, the furniture manufacturing industry, the packaging industry and the transportation industry.

Description

technical field [0001] The invention relates to a production process of honeycomb paperboard, in particular to a method for making honeycomb paperboard with corrugated paper. Background technique [0002] Honeycomb cardboard is a kind of all-paper material. It has been developed for more than ten years in our country. Honeycomb cardboard has many advantages. Therefore, honeycomb cardboard is gradually replacing traditional corrugated cardboard, wood, and foam in the fields of packaging, transportation, and construction. and other materials, the application prospect of honeycomb paperboard is extremely broad, and the improvement of the strength of honeycomb paperboard is of great significance to the wider promotion of honeycomb paperboard. At present, the development of low-carbon economy has become an irresistible trend, and the development of low-carbon economy can be effective Improve resource utilization, protect and improve the ecological environment, and achieve sustain...

Problems solved by technology

[0003] At present, general honeycomb paperboard consists of three parts, namely honeycomb paper core, honeycomb face paper, and adhesive. The compressive strength of honeycomb paperboard mainly depends on the honeycomb paper core. The higher the paper core is, the harder it is to pull it apart during production; on the contrary, the paper core is easy to pull apart, and the strength of the cardboard will decrease accordingly. Usually, the core paper of honeycomb paperboard is 120g / m2. 2 -180g / m 2 Among the single types, the weight of the core paper used for the paper core exceeds 180g / m 2 In the future, the paper core is difficult to stretch in actual production, and the honeycomb cell type is not standard. Due to the low weight of the honeycomb core paper, it is difficult to make a high breakthrough in the compressive strength of the honeycomb paperboard. To solve this problem, there are many Some people have tried, such as adding inserts to the honeycomb paperboard to increase its strength, but the method is complex and the production efficiency is low.
