Abstract

The invention provides a wood-like co-extrusion PMMA modified material, the components of which mainly comprise PMMA ground color material and PMMA grain material, and the weight percentage of the PMMA ground color material and the PMMA grain material is that 50-90 percent of the PMMA ground color material, and 10-50 percent of the PMMA mark material. Plastic steel doors and windows made from thewood-like co-extrusion PMMA modified material has strong viewing and vivid wood grain; can realize the replacement of wood by plastic, thus saving precious wood resources; and has excellent weather resistance, thus widening the application and development of wood-like profiles and being capable of being applied to the manufacturing of indoor and outdoor doors and windows, guardrails, decorative boards, foundation lines, furniture, and the like. The invention also provides the preparation method of the wood-like co-extrusion PMMA modified material, which comprises the steps of weighing, mixing, and extruding. The preparation method is simple, and has extensive raw material resources, low product cost, and wide popularization using value.

Description

technical field [0001] The wood invention belongs to the field of new material chemistry, and specifically relates to a wood grain-like co-extruded PMMA modified material and a preparation method thereof. Background technique [0002] In the prior art, home decoration is still based on timber and aluminum alloy profiles. However, wood is expensive, more susceptible to corrosion and decay, which brings inconvenience to life, and excessive use will cause excessive felling of trees, causing damage to the environment. [0003] The production cost of aluminum alloy profiles is high. The production of one ton of aluminum alloy profiles requires 18,650 degrees of electricity from ore to finished products, while the comprehensive power consumption of one ton of plastic profiles is 7,800 degrees from ore to finished products using the calcium carbide method. It can be seen that aluminum The comprehensive power consumption in the manufacturing process of alloy profiles is more than 2...
