Problems solved by technology

[0003] However, at present, straw material furniture is mainly produced with straw boards, which generally need to go through processes such as cutting, milling, drilling, slotting, veneering, and painting. Not only the production efficiency is low, but also the production cost is high, which is not conducive to the use of straw material value

Embodiment 1

[0025] The mold of the process of forming furniture components with straw materials, the structure is as follows figure 1 and figure 2 As shown, the main components include an upper mold 1, a lower mold 2 and a connector 3, and platforms 12 are provided on both sides of the upper mold 1, and an outwardly convex arc-shaped surface 11 is provided between the platforms 12 on both sides. 12 is provided with connection hole 13, is provided with decorative pattern 14 on arc-shaped surface 11, and decorative pattern 14 can be various shapes such as wavy. A lower platform 22 matching the platform 12 is also provided on both sides of the lower mold 2, and an inner concave surface 21 is provided between the two lower platforms 22, and the inner concave surface 21 matches the arc surface 11 and is used together; In specific use, put the molded furniture component material into the lower mold 2, then cover the upper mold 1, and connect the upper mold 1 and the lower mold 2 with a connec...

Embodiment 2

[0028] A process for forming furniture components using straw materials, including the processes of material preparation, sizing, paving, pre-pressing, hot pressing, cooling, health preservation, and trimming. The specific steps are as follows:

[0029] 1) Material preparation: collect rice and wheat straw, remove soil impurities, etc., and dry to make the moisture content about 12-15%, then cut and grind into medium-long shape (length 10mm-35mm, width 1.2mm-3.3mm) straw scraps.

[0030] 2) Sizing: Use isocyanate resin (polymethylene polyphenyl polyisocyanate, MDI) and dilute with an equal amount of acetone (analytical grade). Using a high-pressure air gun to stir the glue and straw scraps evenly, the amount of glue (mass ratio) is 5%, and the glue is mixed for 8-10 minutes. The ratio (mass ratio) of rice and wheat straw scraps is between 3:7 and 7:3, and the target slab density for pressing is about 0.85g / cm 3 .

[0031] 3) Embryo formation: Teflon paper (used for hot-pres...

Abstract

The invention discloses a process for manufacturing a molded furniture component with straw and a mold adopted therein. The process comprises the steps of material preparation, sizing treatment, paving , pre-pressing, hot-pressing, cooling, curing and trimming. The wheat and rice straw serves as the raw material. Glue is formed by blending of isocyanate resin and acetone. Pressing mass is 50-100 kg during pre-pressing. Pressure is controlled to be 3.5 MPa during hot-pressing. Mold pressing temperature is about 125 DEG C, and mold pressing time is 50 s / mm. Manufacturing operation is easy, the product has a smooth surface and an accurate size, effectiveness is higher specially for products in complicated shapes, time and labor are saved, and performance is excellent. The mold is suitable for ordinary hot presses. By the adoption of the mold, scientific techniques and parameters are provided for manufacturing the furniture component through straw mold pressing, the cost of straw furniture is reduced, the performance of the furniture component manufactured through straw mold pressing is effectively improved, and the physical and chemical indicators of the furniture component accord with the values specified in GB / T21723-2008.

Description

technical field [0001] The invention belongs to the technical field of material and product production, and relates to a process for manufacturing furniture molding components using straw materials and a mold thereof. Background technique [0002] The use of straw material molding furniture components is mainly to put powdery or fibrous rubber-mixed straw material slabs into the mold cavity at the molding temperature, and then pressurize them to form and solidify to form dense straw material molded parts. The molded straw furniture components not only have high dimensional accuracy and good surface finish, but also have a fast production speed, which is conducive to the realization of specialization, batch production and automatic production, and can achieve the purpose of reducing product prices and improving product quality. At the same time, appropriate texture patterns are conducive to enhancing the artistic beauty and added value of furniture. [0003] However, the cur...
