Abstract

The invention relates to a plant fiber environment-friendly, high-strength and light-weight wall body plate which comprises plastic fiber gridding cloth layers on the two sides of the wall body plate and a plant fiber filling layer between the two fiber gridding cloth layers. The plant fiber filling layer is prepared from plant fiber and 40-50% of natural industrial gelling agent by the steps of adding water, fully stirring and then performing one-time hot-press molding by using a molding press, wherein the plant fiber comprises 40-50% of coconut husk, 5-10% of sawdust, 5-10% of bagasse powder. The manufacturing method comprises the following steps: preparing raw materials, mixing the materials, stirring, pouring into a mold, performing hot-press molding, demolding and warehousing for curing to form a finished product. Tropical plant resources are adopted as the raw materials and cement or pulverized coal ash is not used, so that the utilization proportion of agricultural wastes is up to 60-80%, the waste resources can be recycled and the environmental pollution is reduced; and therefore, the manufacturing method accords with a national energy-saving and environment-friendly policy, and a product has the characteristics of low production cost, light weight, easiness in mounting, excellent performances of being nailed, drilled, planed and pasted, and is good in earthquake resistance and suitable for being used as internal and external wall bodies of houses.

Description

String environment-friendly, high-intensity light wall board

Technical field

The present invention is a kind of natural plant fibre that utilizes, and the environment-friendly, high-intensity light wall board that plastic fiber grid cloth and gelling agent are processed belongs to the composite wall material technical field.

Background technology

China is a forest, the country that land resources is relatively deficienter, and forest and soil, mineral resources all are lower than world average level per capita.The modernization of the country development is built and is faced very big resource consumption pressure; Therefore preserve the ecological environment, economize the land resource, reduce the important policies that energy consumption is a national development energetically; Spell out in the national for this reason materials for wall Tenth Five-year plan: " materials for wall innovation is a protection land resources; energy conservation, and comprehensive utilization of resources improves the major measure of environment; also be the important content of the strategy of sustainable development ", " must promote and research and develop have efficient, energy-conservation, joint is native, profit is given up, the composite wall material of environmental protection, lightweight, high-strength, insulation, heat insulation, fireproof performance ".For various reasons, the problem of some safeties, durability and economy has in use appearred in these building material products at present, forces vast materials for wall enterprise and scientific research personnel further to explore new wall board.

Summary of the invention

For overcoming the above-mentioned defective of existing novel wall material; The purpose of this invention is to provide a kind of string environment-friendly, high-intensity light wall board; To be fit to growing construction market needs; Progressively realize the demand for development of country, satisfy vast materials for wall enterprise and user's hope materials for wall.

For realizing goal of the invention; The inventor goes through concentrating on studies and testing for many years; Finally develop technical scheme of the present invention: design string environment-friendly, high-intensity light wall board, be made up of the plastic fiber grid layer of cloth on ash wall body plate two sides and the string packed layer between the two fiber mesh layer of cloth skies, its feature is: 1, said string packed layer is by coconut palm chaff 40-50%; Wood chaff 5-10%; String and natural industrial gelling agent 40-50% that bagasse powder 5-10% forms, after adding water and fully stirring, hot in nature next time molded at moulding press.2, the coconut palm chaff of said string is pulverized by coconut husk and coconut palm branch and is formed, and wooden chaff is that branch or sawdust pulverizing form, and bagasse is pulverized for the sugarcane waste material that presses sugar and formed, and its fineness is the 150-180 order.3, said natural industrial gelling agent is a magnesium oxide powder, and fineness is 200 orders.4. the side at said packed layer is provided with the protruding key of the vertical structure that is used for intercalation, and opposite side is provided with and is used for chimeric vertical structure groove, and groove is rectangle or swallow-tail form, and its width and length are slightly larger than the width and the length of protruding key, so that chimeric smoothly during assembly unit; 5. in said division center layer, be provided with many through holes 5 that vertically distribute.

Compared with prior art, the present invention has following substantive distinguishing features and marked improvement:

1, because the present invention adopts the abundant tropical plants resource in Hainan, be raw material like branch, coconut husk, the bagasse of cocoanut tree, do not use cement or coal dust grey; Make and utilize the ratio of agricultural wastes to reach 60-80%, both belonged to wasted resources, reduced environment pollution again; Therefore the policy that meets national energy-conserving and environment-protective; And the production cost is low, and the huge market demand has the wide pre-sales scape that disappears;

2, product weight is light: every weight per square meter is merely 1/5 of clay common brick wall weight;

3, body of wall is thinner: compare with brick mix structure, can enlarge usable floor area 10-22%;

4, install easily: take the device of shifting block type aggregate erection, efficient and convenient, the 3-5 that can increase work efficiency doubly, and have can follow closely, can bore, can dig, the premium properties characteristics of Pasting;

5, intensity is high, and anti-aging: the compressive strength assay is higher than national standard;

6, energy-conservation: this ash wall body plate thermal transmittance surpasses national standard, and body of wall is energy-conservation to be reached more than 65%;

7, water resistance is good: moisture content is merely 10%, is not afraid of the sunlight that exposes to wind and rain and is exposed to the sun;

8, fireproof performance reaches national A grade standard, and belong to and do not fire body, and nontoxic, harmless, pollution-free, radiationless, belong to the environmental type building materials;

9, wallboard light weight anti-seismic performance is good, and the house is used and builds in the many shakes area that is particularly suitable for taking place frequently in natural calamity.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the present invention is further specified:

Fig. 1 is a structural representation front view of the present invention;

Fig. 2 is A among Fig. 1-A sectional view.
