Damp-proof wood-plastic material for water meter shell

Abstract

The invention discloses a damp-proof wood-plastic material for a water meter shell. The damp-proof wood-plastic material contains the following raw materials in parts by weight: 50-80 parts of thermoplastic plastic, 10-20 parts of nano hydrophobic granules, 5-8 parts of a modified bamboo fiber, 2-5 parts of a compatilizer, 1-3 parts of a stabilizer, 0.5-1 part of an antioxidant and 1-5 parts of aids, wherein the nano hydrophobic granules contain nano calcium carbonate and polydimenthyl silane; and the modified bamboo fiber is a mixture of an alga inhibitor and bamboo fiber powder. Due to addition of the nano calcium carbonate and the polydimenthyl silane as the nano hydrophobic granules into the thermoplastic plastic, the damp-proof property of a product is improved, and with the combination of the modified bamboo fiber, the humidity of the surface of the material is greatly degraded, production and propagation of algae are effectively avoided, and the hydrophobic damp-proof properties of the shell material are further improved.

Description

technical field [0001] The invention relates to the technical field of wood-plastic materials, in particular to a moisture-proof wood-plastic material for water meter casings. Background technique [0002] At present, the water meter housing materials mainly include cast iron, brass, stainless steel and plastic materials. Although metal shells have the advantages of high strength and recyclability, such as cast iron and brass, the price of metal shells is relatively high, such as stainless steel, and it is easy to cause secondary pollution to water quality. For example, aluminum alloy is very easy to Corrosion, harmful to human health. Wood-plastic materials have the advantages of high production efficiency, low energy consumption, light specific gravity, no rust, corrosion resistance, high precision of finished products, exquisite appearance, low price, etc., and become ideal materials for water meter shells. [0003] Wood-plastic materials have good corrosion resistance ...

AI Technical Summary

Problems solved by technology

[0003] Wood-plastic materials have good corrosion resistance and mechanical strength, but the toughness of ordinary wood-plastic materials is not particularly ideal, and the water meter shell is in a humid environment for a long time, and the surface of the shell is easy to grow algae, which greatly improves the waterproof performance of the shell material. Reduced, even after the algae dries, its waterproof performance cannot be restored to its original state
