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

Plant fiber environment

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 made belongs to the composite wall material technical field.

Background technology

China is a forest, the country that land resources is deficienter, and forest and soil, mineral resources are all lower than world average level per capita.The modernization of the country development is built and is faced very large resource consumption pressure, therefore preserve the ecological environment energetically, economize the land resource, reducing energy consumption is the important policies of national development, in the national materials for wall Tenth Five-year plan, explicitly point out: " the materials for wall innovation is protection land resources for this reason, energy conservation, comprehensive utilization of resources, improve the major measure of environment, also the important content of the strategy of sustainable development ", " must promote and research and development have efficiently, energy-conservation, joint soil, profit is useless, environmental protection, lightweight, high-strength, insulation, heat insulation, the composite wall material of 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 defect of existing novel wall material, the purpose of this invention is to provide a kind of plant fiber environment, to be applicable to growing construction market needs, progressively realize the demand for development of country to materials for wall, meet vast materials for wall enterprise and user's hope.

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, by the plastic fiber grid layer of cloth on ash wall body plate two sides and the string packed layer between two fiber mesh layer of cloth skies, formed, its feature is: 1, a side at described packed layer is provided with for the protruding key of the vertical structure of intercalation, opposite side is provided with for chimeric vertical structure groove, and groove is rectangle or swallow-tail form, its width and length are slightly larger than width and the length of protruding key, so that chimeric smoothly when assembled, in described division center layer, be provided with many through holes that vertically distribute, described string packed layer is by coconut palm chaff 40-50%, wooden chaff 5-10%, and string and natural industrial gelling agent 40-50% that bagasse powder 5-10% forms, after adding water and fully stirring, next time hot in nature molded at moulding press.2, the coconut palm chaff of described string is pulverized and is formed by coconut husk and coconut palm branch, and wooden chaff is that branch or sawdust pulverizing form, and bagasse is pulverized and formed for the sugarcane waste material that presses sugar, and its fineness is the 150-180 order.3, described natural industrial gelling agent is magnesium oxide powder, and fineness is 200 orders.

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, branch, coconut husk, bagasse as cocoanut tree are raw material, do not use cement or coal dust ash, make to utilize the ratio of agricultural wastes to reach 60-80%, both belonged to wasted resources, reduced again environment pollution, therefore meet the policy of national energy-saving environmental protection, and the production cost is low, the huge market demand, have the wide pre-sales scape that disappears;

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

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

4, install easily: take plate board assembling to install, 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, 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 only 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, is particularly suitable for the many shakes that take place frequently in natural calamity area and uses and build house.
