Abstract
The invention discloses a production process of a straw density board. The straw density board is processed by taking crop straws as a main raw material, and adding paraffin-resin emulsion, the density board is prepared from the following ingredients: 100 parts of the crop straws, 3 to 4 parts of a water-proofing agent and 45 to 55 parts of a binding agent; the specific work flow comprises preparing the crop straws, screening, cutting, boiling, smashing, adding the binding agent, mixing, forming, spraying a surface layer on a formed wet sheet, drying and sanding. The process has the beneficial effects that the waste crop straws are used as the raw material, so that the problem of environment pollution caused by straw burning and stacking is solved, the finished product has the characteristics of being compact, high in strength, and simple in manufacturing process.
Description
Technical field
The present invention relates to a kind of production technology of artificial density board, specifically refer to a kind of production technology utilizing waste crop straws to manufacture densified straw board.
Background technology
Existing wood-based plate, if fiberboard, particieboard etc. are all produce as material construction with timber.Because the raw material sources of wood type limit by environmental protection and other reason, its quantity delivered is not only limited, and price is higher.So more domestic enterprises and research institution at present, all the time in searching artificial board and other available alternative materials.And agricultural crop straw belongs to renewable resource, all can produce a large amount of stalks every year, except being recovered except utilization on a small quantity, most stalk is all burned or is discarded, namely the waste of resource is caused, pollute environment again, the construction material developing with stalk the densified straw board being raw material is one of effective way solving this contradiction.
Summary of the invention
In order to solve above-mentioned Problems existing, the invention provides a kind of production technology of agricultural crop straw density board.
The present invention is achieved through the following technical solutions: a kind of production technology of densified straw board, and be that primary raw material adds wax-rosin emulsion and is processed into agricultural crop straw, its batching is: agricultural crop straw 100 parts, waterproofing agent 3-4 part, adhesive 45-55 part; Concrete production procedure is: agricultural crop straw-screening-cut-out-boiling-pulverize-add adhesive-spice-shaping-spray top layer-drying-sanding on shaping wet mat.
Described agricultural crop straw selects rice straw, Wheat Straw, maize straw, broomcorn straw, reed rod wherein one or more.
Described waterproofing agent makes wax-rosin emulsion by paraffin and rosin, rosin derivative and water by weight 90-100:45-50:5-20.
MDI glue selected by described adhesive.
The top layer of described densified straw board is the mixture of fine fibre and waterproofing agent, and wherein fine fibre is 100:4-9 with the ratio of waterproofing agent.
Beneficial effect of the present invention is: the present invention, owing to make use of agricultural waste material stalk as raw material, solves crop straw burning and stacks the problem of environmental pollution that causes, and manufactured goods have that matter is close, intensity is high, the simple feature of manufacturing process.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is further illustrated:
Embodiment 1
Raw material: Wheat Straw 100 parts, waterproofing agent 4 parts, 50 parts, MDI glue
Preparation method:
1, Wheat Straw is sieved, remove impurity;
2, Wheat Straw is cut into 10 cm, by Wheat Straw boiling more than 1 hour at 150 DEG C;
3, then Wheat Straw is added water and be ground into the particle that particle diameter is less than 4mm;
4, the Wheat Straw of pulverizing is added MDI glue to stir;
5, cold moudling obtains wet mat;
6, waterproofing agent is prepared: paraffin and rosin, rosin derivative and water make wax-rosin emulsion by weight 100:50:10.
7, the skin-material of waterproofing agent and fine fibre mixing system is ejected on wet mat;
8, dry
9, sanding
Embodiment 2 according to the method for embodiment 1, raw material choose: rice straw 100 parts, waterproofing agent 3 parts, 45 parts, MDI glue.
