Problems solved by technology

[0008] For interior doors processed by techniques such as engraving or hollowing out, the requirements for the accuracy of the material itself and processing equipment are relatively high, resulting in high costs and high product sales prices
[0009] Through post-processing technology such as molding, the appearance of the door leaf is relatively simple and single, and the size control is unstable, resulting in a decline in the quality of the overall door leaf, relatively poor sound insulation effect, weak moisture resistance, and short service life

Abstract

The present invention provides a environmental protection indoor door completely using waste, wherein 42.5-44.5% of magnesium oxide, 20.2-25.5% of magnesium sulfate, 9.5-11.5% of agricultural and industrial waste, 1.7-2.1% of a foaming agent, 1.6-1.9% of a composite modifier, 0.01% of a composite water retention agent, 0.08% of a composite emulsion, 0.18-0.25% of PP fibers and 20-27% of a fiber mesh cloth are subjected to crushing, fusion and mold pressing so as to obtain the environmental protection indoor door. According to the present invention, the industrial waste, the agricultural waste and other waste are adopted as the raw materials to produce the environmental protection health product, such that the environmental damage and other problems caused by use of a lot of wood are solved, and the damage of the waste on the environment is solved.

Description

technical field [0001] The invention relates to a building door, in particular to an environment-friendly interior door. Background technique [0002] At present, the interior doors produced on the market are mainly wooden doors. Wooden doors can be divided into original solid wood doors, solid wood finger-jointed doors, solid wood composite doors, molded doors, polymer doors, steel-wood doors, PVC doors, and plywood doors. [0003] 1. The original solid wood door is made of natural logs from the forest as the door core, and then scientifically processed through blanking, planing, tenoning, drilling, carving, shaping and other processes. [0004] 2. The solid wood finger-jointed door refers to the wood that has been sawed and finger-joined. The wooden door is processed through the same process as the solid wood door of the log. The performance is much more stable than that of the solid wood door of the log, and it is not easy to deform. The wood used for all solid wood d...
