Abstract

In order to improve the fire resistance, water resistance and wear resistance of ordinary plywood products in the wood processing industry, three composite structures of plywood products S1, S2 and S3 were designed in this paper, and a reasonable production process was proposed. Through the physical and mechanical properties and fire resistance testing and technical and economic analysis, the applicability of composite plywood was evaluated. The results of the study showed that the physical mechanics of the three kinds of composite structure plywood met the standard requirements, and their fire resistance was far better than that of ordinary plywood. Among them, the S1 structural board had the best overall physical and mechanical properties. The S3 structural board showed the best fire resistance, which was about 1.9 times more than that of ordinary plywood, and the added cost was the lowest. The thin cork board added to the S2 structural board had poor fire performance since the air in the cork board cavities had a certain combustion-supporting effect, which inhibited the fire resistance of high-pressure laminate (HPL) layer. Moreover, the additional cost of the S2 board was the highest, and its comprehensive performance was the worst. The S3 structural plywood product composed of HPL fireproof board with a thickness of about 1 mm in the surface layer and ordinary plywood with a thickness of about 12 mm in the core layer was the most cost-effective product, which could meet the needs of various fields such as construction, home furnishing, decoration and transportation.
