Embodiment Construction
[0013] The thermal insulation, energy-saving and environment-friendly plant fiber cement composite slab is characterized in that it is made of the following raw materials in parts by weight: plant fiber 33, Portland cement 35, fly ash 47, waste concrete 11, Nano-titanium dioxide 1.6, calcium fluoride 0.2, calcium chloride 0.5, magnesium oxide 0.6, hollow fiber 6, styrene-acrylic emulsion 14, linseed oil 7, polyoxyethylene abietic acid ester 11, appropriate amount of water.
[0014] The preparation method comprises the following steps:
[0015] (1) Put the plant fiber in an oven at 105°C for about 3-4 hours, dry it at room temperature, tap it with a leather hammer until the pectin is removed and crushed to a diameter of 3-6mm, and place it in a mass concentration Soak it in 10% styrene-acrylic emulsion for 24 hours, dry it after pressing it dry, spray it with mist linseed oil in the state of blowing to a tumbling state, and dry it;
[0016] (2) Calcinate waste concrete at 660-...

Abstract
The present invention discloses a thermal insulation energy-saving environmentally friendly plant fiber cement composite plate and a producing method thereof, the thermal insulation energy-saving environmentally friendly plant fiber cement composite plate comprises the following raw materials by weight: 27-37 parts of vegetable fibers, 28-35 parts of Portland cement, 45-50 parts of fly ash, 10-20 parts of abandoned concrete, 1.3-2.7 parts of nano-titanium dioxide, 0.2-0.4 part of calcium fluoride, 0.3-0.6 part of calcium chloride, 0.6-0.9 part of magnesium oxide, 4-7 parts of hollow fiber, 12-15 parts of styrene-acrylic emulsion, 4-7 parts of linseed oil, 9-11 parts of rosin acid polyoxyethylene ester, and proper amount of water; the thermal insulation energy-saving environmentally friendly plant fiber cement composite plate has the advantages of thermal insulation, fire-retardance and the like, the comprehensive utilization level of plant fiber can be improved, and serious damage caused by improper handling of waste resources can be reduced.
Description
technical field [0001] The invention relates to the technical field of building materials, in particular to a heat-insulating, energy-saving and environment-friendly plant fiber cement composite strip and a manufacturing method thereof. Background technique [0002] Since the 1990s, in terms of the choice of living environment, people are no longer satisfied with ordinary housing, but are pursuing building materials with natural characteristics, that is, environment-friendly new materials. Environmentally harmonious building materials must meet the characteristics of heat preservation and energy saving, sound absorption and sound insulation, water resistance and fire prevention, non-toxic and tasteless, light weight, high strength, and safety. Plant fiber cement composite slats are a new type of environmentally harmonious building materials. Fiber refers to annual plant fibers, mainly crop straws such as corn stalks, wheat stalks, cotton stalks, hemp stalks, etc. [0003] T...
