Abstract
The invention belongs to the technical field of amino film plastics and relates to a material special for wood-like amino film plastics, particularly and suitably applied to making wood-like products or dark-colored products. The wood-like amino film plastics are prepared from the following components in percentage by weight: 73-85 percent of amino resin, 0.2-1.0 percent of curing agent, 0.4-0.8 percent of lubricant, 0.1-0.3 percent of surfactant, 15-25 percent of crop fiber powder and / or wood powder and 0-2 percent of pigment. An original production process is not changed, originally added paper pulp is replaced with waste crop straw powder or wood powder in a kneading process and the fluidity of the amino film plastics and the time of the amino film plastics in a ball mill are controlled to obtain pigment grains in different grain sizes. When a product is formed, the proportion of the pigments is adjusted according to the wood grain requirements to obtain the needed wood grain effect.
Description
technical field [0001] The invention belongs to the technical field of amino molding compounds, and in particular relates to a special material for imitation wood amino molding compounds, which is especially suitable for the preparation of imitation wood products or dark-colored products. Background technique [0002] Amino resin is a general term for resins formed by polycondensation of compounds containing amino groups and formaldehyde. Important amino resins include urea-formaldehyde resin, melamine-formaldehyde resin and aniline-formaldehyde resin. Generally, it can be made into aqueous solution or ethanol solution, and can also be dried into powder solid. Most of them are hard and brittle, and fillers are required when used. Amino resin is oil-resistant, solvent-resistant, and has excellent electrical properties. In addition to being used to make molding compounds, it is also used as decorative panels, coatings, wood adhesives, and fiber treatment agents. [0003] Ami...
