Humidity-adjustable wall decorative composite board and preparation method thereof

Abstract

The invention belongs to the technical field of decorative materials, and particularly relates to a humidity-adjustable wall decorative composite board and a preparation method thereof. The humidity-adjustable wall decorative composite board sequentially comprises a honeycomb structure board, a coating and decorative cloth from inside to outside. The coating is prepared from the following substances in parts by weight: 80-150 parts of acrylic emulsion, 50-80 parts of VAE emulsion, 5-12 parts of a drying agent, 8-15 parts of modified attapulgite, 3-8 parts of mesoporous silica, 15-35 parts of polyvinyl alcohol, 3-8 parts of a cross-linking agent and 0-5 parts of an auxiliary agent. The honeycomb structure board is made of bamboo and wood fibers and PVC resin. The solid content of the acrylic emulsion is 60%-70%. The solid content of the VAE emulsion is 55%-75%. By adopting the acrylic emulsion and the VAE emulsion as main components of the coating, the coating can be quickly cured underthe action of waste heat of the honeycomb structure board, and the decorative cloth can be tightly adhered to and covers the surface of the coating, so that the operation time is shortened, and the economic benefit is improved.

Description

technical field [0001] The invention belongs to the technical field of decorative materials, and in particular relates to a humidity-adjustable wall decorative composite board and a preparation method thereof. Background technique [0002] With the rapid development of the economy, the increasing scarcity of resources has become a global problem, and energy conservation, emission reduction and sustainable development have been included in the country's major policies. It is imperative to reduce building energy consumption and pollution emissions, save resources, protect the environment, and realize the harmonious coexistence of buildings and nature. The promotion of energy-saving, land-saving, low-carbon and environmentally friendly new building wall materials is an urgent need for the development of circular economy and the construction of a conservation-oriented society. At the same time, it is also of great significance to save resources, protect cultivated land and impro...
