Problems solved by technology

[0005] After investigating the current situation of the existing partition boards, the inventor found the existing defects, and also heard that a large number of crop straws have been discarded in recent years, causing major social problems. The purpose of the present invention is to overcome the defects of using plant straws in the prior art. Make full use of waste plant straw resources, use plant fiber and cement as the main raw material composite material, replace wooden partition boards or other building materials, and produce a soundproof and fireproof partition board

Embodiment 1

[0011] Embodiment 1 of a soundproof and fireproof partition board of the present invention is made of the following raw materials in parts by weight in kilograms: 45 plant fibers, 50 cement, 7 antifungal agents, 3 water reducing agents, 10 waterproofing agents, and 25 strengthening agents.

Embodiment 2

[0012] Embodiment 2 of a soundproof and fireproof partition board of the present invention is made of the following raw materials in parts by weight in kilograms: plant fiber 0.9, cement 9, antifungal agent 0.3, water reducing agent 0.1, waterproofing agent 0.4, reinforcing agent 5.

Embodiment 3

[0013] Embodiment 3 of a soundproof and fireproof partition board of the present invention is made of the following raw materials in parts by weight in kilograms: 0.1 plant fiber, 1 cement, 0.03 antifungal agent, 0.01 water reducing agent, 0.05 waterproofing agent, and 0.5 strengthening agent.

[0014] According to the technological process used in the above-mentioned examples, first collect plant straw, crush it, and then refer to the wax removal technology in the papermaking process to remove the wax in the straw and extract plant fibers. According to the different uses of the partition board, the Ratio of each raw material, add portland cement, each additive, add appropriate amount of water and mix evenly, fill in the partition mold, pressurize the mold panel to form, after demoulding, refer to the concrete product maintenance method for curing for a period of time, and slightly repair , and finally carry out surface treatment, that is, stick a layer of wood grain decorative...

Abstract

The present invention relates to building material, and provides one kind of sound isolating fireproof partition board. The sound isolating fireproof partition board is produced with plant fiber and cement as main material as well as proper amount of mildew inhibitor, water reducing agent, waterproofing agent, intensifier, etc, and through mixing, forming and surface treatment. It has the features of sound isolation, fire prevention, decoration, light weight, no toxic and harmful matter release, high corrosion resistance, high strength, low cost, etc.

Description

technical field [0001] The invention belongs to the technical field of building materials, and relates to a composite material with plant fiber and cement as main raw materials, in particular to a soundproof and fireproof partition board. Background technique [0002] Some of the existing partition boards are made of wood boards and some of them are made of fiber boards, which have the disadvantages of consuming wood, no sound insulation and no fire prevention. The partition boards made need to be decorated separately. [0003] Some people have tried to use wheat straw as the main raw material to make MDF with organic adhesives such as melamine or phenolic resin and urea-formaldehyde resin, but this material will release formaldehyde, pollute the environment, and have poor strength and water resistance; some people use wheat straw and cement Density board, but because the wax on the surface of wheat straw affects its strength and scope of use, it is not suitable for use as a...
