Abstract

The present invention relates to a building plate material-plant straw fibre reinforced light hollow strip plate. Said invention contains Portland cement, active mineral additive material, cinder or broken cermsite, pearlite or zeolite granules, plant straw fibre and hardening agent or/and interface treating agent. Its production method includes the following steps: pulverizing, pretreatment, mixing by adding water, extrusion forming and curing so as to obtain the invented product.

Description

Plant straw fiber reinforced light hollow slat
Technical field
The present invention relates to a kind of building board, particularly a kind of with the agriculture and industry waste be feedstock production light hollow slat.
Background technology
Method with agricultural crop straw manufacturing building board mainly is to adopt magnesia oxychloride cement as cementitious material at present, as by Patent Office of the People's Republic of China's invention disclosed patent application in 22 days November calendar year 2001 " light wall material and manufacture method " (application number: 01131564), raw material by following weight portion is formed: magnesia 80-120 part, magnesium chloride 35-45 part, French chalk 3-6 part, waterproof powder 3-6 part, Lauxite 0.4-0.8 part, inserts 40-80 part, 0.5 part of additive: inserts is wood sawdust, pulverizing straw or agricultural crop straw etc.Because magnesia oxychloride cement is not water-fast, easily returns halogen, the therefore necessary more chemicals of admixture could keep goods stable.In addition by Patent Office of the People's Republic of China's invention disclosed patent application on the 18th " straw fibreboard made and manufacture method thereof " in 2004 02 month (application number: 03148168), with dry stalk is main raw material(s), its component comprises stalk fine fibre, lumber fibre, cement, resin, adhesive, the percentage by weight of each component is: stalk fine fibre 20-95%, lumber fibre 0-80%, cement 0-50%, resin 0-30%, adhesive 3-10%, water is an amount of.Its manufacture method comprises: selected, clean stage, cut-out stage, blowing stage, squeezing stage, operations such as plate forming stage.This sheet material is added with more resin and adhesive, also needs a considerable amount of lumber fibres, and manufacturing process is more complicated also, and manufacturing cost is higher.
The available technology adopting extrusion molding is produced the existing business-like production line of light hollow slat.Its used raw material are mainly portland cement, slag, perlite and haydite etc.But the sheet material rupture strength of producing is lower, and drying shrinkage is bigger.In order to increase its rupture strength, often need to lay fiberglass gridding cloth on the surface, both increased cost of production, make complex manufacturingization again.
Summary of the invention
In order to overcome the deficiencies in the prior art and defective, the invention provides a kind of plant straw fiber reinforced light hollow slat.This hollow lath can utilize agriculture and industry waste as raw material in a large number, need not use the frequent fiberglass gridding cloth that uses of general sheet material as reinforcing material, it is simple both to have had production technology, can further improve the rupture strength of product simultaneously, and product quality meets the regulation of national standard.
Technical scheme of the present invention is as follows: a kind of plant straw fiber reinforced light hollow slat, it is characterized in that: described light hollow slat contains portland cement, the active mineral admixture, slag or broken haydite, perlite or zeolite rock particle, straw fiber, hardening accelerator are or/and interface treating agent and water, and the weight proportion of above-mentioned each component is:
Portland cement: 1 part
Active mineral admixture: 1~1.5 part
Slag or broken haydite: 1.5~2.5 parts
Perlite or zeolite rock particle: 0~1 part
Straw fiber: 0.04~0.1 part
Hardening accelerator is or/and interface treating agent: 0.02~0.07 part,
And with the preparation of following method: through mechanical crushing, preliminary treatment becomes length to be not more than the fiber that 20mm, width are not more than 0.2mm with straw; Described material and water are mixed and stirred simultaneously, make harsh mix,, behind nature or hydrothermal curing, obtain finished product with fixed or portable extrusion shaping machine moulding.
Hardening accelerator of the present invention is one or more in water glass, calcium chloride, saltcake, the NaOH; Described interface treating agent is a kind of in Lauxite, polyvinyl alcohol emulsion or the water glass; Described active mineral admixture is one or more in flyash, slag powders, calcining matchmaker spoil powder, inferior kaolin, phosphorus slag or the magnesium slag.
The present invention compared with prior art, have the following advantages and the high-lighting effect: plant straw fiber reinforced light hollow slat provided by the present invention adopts a large amount of industry and agricultural wastes, help preserving the ecological environment, effectively reduce the cost of production of sheet material simultaneously, have good society and economic benefit; Stalk only needs simple mechanical crushing to handle, and does not need chemical treatment, does not have waste water in process of production and discharges environmentally safe; As reinforcing material, make rupture strength raising 15%, the drying shrinkage of the sheet material of production reduce 10% with stalk fibre; Can produce the sheet material of different size specification according to user's requirement; Do not need mould in the manufacturing process, reduce once investment.The fireproof performance A level that is up to state standards, various performances satisfy the technical requirements of national standard.
The specific embodiment
Embodiment 1:
1 part of portland cement, 1 part in flyash, 2.5 parts in slag, pulverize 0.04 part of straw fiber, 0.04 part of hardening accelerator, employing water glass is hardening accelerator, also can adopt a kind of in calcium chloride, saltcake, the NaOH or several, 0.03 part of interface treating agent adopts Lauxite, and also can adopt polyvinyl alcohol emulsion or water glass is interface treating agent.Material is mixed in forced mixer and is made for harsh mix.Compound is conveyed into the extruded type forming machine, is vibrating and extruding double action compacted under, and is being cut into sheet material according to required size, through behind the nature or hydrothermal curing of certain hour, obtains finished product.
Embodiment 2:
1 part of portland cement, 1.5 parts of ground slags, 1.5 parts in slag, 1 part of perlite is pulverized 0.1 part of straw fiber, 0.02 part of interface treating agent.Material is mixed in forced mixer and is made for harsh mix.Compound is conveyed into the extruded type forming machine, is vibrating and extruding double action compacted under, and is being cut into sheet material according to required size, through behind the nature or hydrothermal curing of certain hour, obtains finished product.
Embodiment 3:
1 part of portland cement, 1.2 parts of inferior kaolin, 2.0 parts of broken haydites, 0.6 part on zeolite rock is pulverized 0.06 part of straw fiber, 0.06 part of hardening accelerator.Material is mixed in forced mixer and is made for harsh mix.Compound is conveyed into the extruded type forming machine, is vibrating and extruding double action compacted under, and is being cut into sheet material according to required size, through behind the nature or hydrothermal curing of certain hour, obtains finished product.
