The invention relates to a method for preparing a greening fence based on waste plastics and straw. The method comprises the following steps: 1) naturally airing the collected plant straws, then cutting and crushing to prepare straw powder for later use; 2) collecting the waste plastics and related products, washing, drying and then performing crushing treatment to perform plastic particles for later use; 3) drying the straw powder till the water content is within 5% and further performing modification treatment on the straw powder; 4) performing steam sterilization on the plastic particles, further drying, mixing with the modified straw powder in the step 3), uniformly mixing and then sending into a granulating machine for granulating to obtain mixed particles for later use; 5) burdening the mixed particles; and 6) putting the materials in the step 5) into a hot runner co-extrusion mold for hot melting and extrusion, well mixing the materials, and then introducing into a hot runner for being jointed with a whole molding production line for molding. The prepared product has great strength, hardness, acid-alkali resistance, corrosion resistance and no deformation and is easy to recover, and is an environment-friendly material.

The invention discloses a preparation method for functional finishing of wool fabric through plant pectin. The method comprises the following steps that 1, a pectin finishing solution is prepared, the plant pectin extracted through the method is fully dried at the normal temperature, the dried plant pectin is squeezed into pectin powder, pectin of a certain weight is obtained through weighing and put into a measuring cup, then distilled water of a certain volume is obtained through weighing and poured into the measuring cup containing the pectin, the mass fraction of the pectin in the prepared finishing solution ranges from 3% to 6%, the bath ratio of the finishing solution is 1:40-50, and finally the pectin and the distilled water are heated in a set thermostat water bath and stirred continuously by a glass bar for 30-40 minutes until the pectin is completely dissolved; 2, the pectin solution is finished, after the pectin is completely dissolved, prepared wool fabric is scoured and then completely soaked into the finishing solution, timing is conducted when the wool fabric is completely padded, the wool fabric is continuously stirred by the glass bar, after about 30-40 minutes, the wool fabric is taken out, washed 2-3 times through clear water and twisted dry, and the wool fabric is placed in a fixed-temperature and fixed-humidity laboratory and naturally dried.

The invention discloses a production process of a super-stable solid wood floor. The production process comprises following steps that a floor blank and wax are jointly put into a heating cavity, theheating cavity is in the closed state, air in the heating cavity is pulled away, the heating cavity is in the vacuum state, the floor blank and the wax in the heating cavity are subjected to temperature rise to 100 to 120 DEG C while air exhaust is carried out, after the floor blank is taken out, the floor blank is subjected to standing to be in the normal temperature state, under the natural state, standing is carried out for 15 to 20 days, the floor blank is subjected to sanding thickness fixing, grooving and surface oil or paint coating in sequence, and the finished floor is obtained. The non-deformability, corrosion resistance, and worm eaten preventing effect of the solid wood floor can be obviously improved, and the service life is prolonged.

The present invention is a moisture-proof method for coating the surface of wooden materials. The process steps are as follows: 1. cleaning the surface of the wooden material; 2. placing the wooden material after the surface cleaning treatment in a vacuum coating machine; The waterproof coating material is evaporated into a gaseous state in the evaporation chamber, and then enters the cracking chamber, where it is cracked into active monomers with reactive characteristics; this active monomer is gradually deposited on the surface of the wood material in the deposition chamber to aggregate and crystallize; forming a thickness of 1~5um Highly cross-linked pinhole-free polymer film waterproof membrane layer. Advantages: reduce the deformation of wood materials after moisture absorption, and greatly improve the waterproof and moisture-proof performance of materials. Maintain the unique color, mechanism and performance of the wood itself, improve the moisture-proof, mildew-proof, anti-corrosion, and moth-proof properties of the material, and use wood resources more effectively.

The invention relates to a waterproof, fireproof, and insect-proof plant fiber and a moulding technology thereof, and belongs to the technical field of construction filling materials. The plant fibercomprises following components in parts by weight: 50 to 60 parts of wheat straws, 10 to 20 parts of peanut shell powder, 5 to 20 parts of a glutinous rice-starch binder, 20 to 22 parts of calcium hydroxide, 3 to 10 parts of paraffin waterproof powder, and 1 to 5 parts of fireproof fibers. Wheat straws and peanut shell powder are taken as the basic materials and are subjected to an antiseptic treatment; the glutinous rice-starch binder and paraffin waterproof powder are compounded so as to firmly bind the wheat straws, peanut shell powder, and other filling materials together; a water repellent layer is formed on the surface of the plant fiber, thus the surface of the plant fiber will not be wetted; moreover, fireproof fibers are added, and the provided plant fiber is resistant to water, fire, and insects.

The invention relates to a waterproof, fireproof, and moth-proof plant fiber and its molding process, belonging to the technical field of building material fillers. The plant fiber includes the following components in parts by weight: 50-60 parts of wheat straw, 10-20 parts of peanut shell powder, 5~20 parts of glutinous rice-starch binder, 20~22 parts of calcium hydroxide, 3~10 parts of paraffin waterproof powder and 1~5 parts of fireproof fiber; with wheat straw and peanut shell powder as the base material, and for wheat straw, Peanut shell powder is subjected to anti-corrosion treatment, compounded with glutinous rice-starch binder and paraffin waterproof powder, which can firmly bond wheat straw, peanut shell powder and other fillers, and form a hydrophobic layer on the surface of plant fibers to prevent moisture from clouding Wet the surface of the plant fiber, and add the fire-proof fiber to prepare the plant fiber with functions of waterproof, fire-proof and moth-proof.

The invention discloses a method for modifying a wood board. The epoxy glue is fully filled into capillaries of the wood board and uniformly distributed on the surface of the wood board through negative pressure filling technology, and then the wood board is cured. The modification method of a wood board of the present invention can not only effectively increase the corrosion resistance and moth resistance of wood, but also improve the impact resistance and wear resistance of wood after the epoxy glue is cured, effectively improving the wood board's durability. Use performance.
