Abstract

The invention relates to a composite material for an outdoor table tennis table. The composite material comprises the following raw materials in parts by weight: 90-110 parts of cement, 55-65 parts of river sand, 0.5-0.8 part of redispersible latex powder, 0.3-0.6 part of polypropylene fiber, 4-8 parts of fly ash, 3-6 parts of bagasse ash, 0.3-0.8 part of lignocellulose, 0.2-0.4 part of a reducing agent, 1-3 parts of metakaolin loaded zirconium dioxide, 36-48 parts of water, 5-10 parts of epoxy resin, 1-2 parts of a curing agent and 0.4-1 part of an auxiliary agent. The problems that an existing wooden table tennis table top is not suitable for outdoor use, not resistant to corrosion and prone to aging are solved.

Description

technical field [0001] The invention relates to a composite material for an outdoor table tennis table. Background technique [0002] Table tennis is China's national ball game and is a popular ball game in the world. Ping-pong table is requisite facility when carrying out table tennis, and table tennis table generally comprises table top, support and block, and described support is located at the bottom of table top, and described block is perpendicular to table top and table top is divided into symmetrical two parts. Table tennis table tops can be made of any material, such as wood, fiberglass, marble, SMC boards, sawdust boards, etc. According to international regulations, table tennis table tops should be made of solid wood and must have certain elasticity. [0003] Table tennis is widely used in indoor or outdoor sports, and the outdoor table tennis table requires its table top to withstand the sun and rain, with the characteristics of not easy to age, long service lif...
