1. Plastic materials: plastics are mainly composed of natural resin or synthetic resin, and participate in appropriate fillers, plasticizers, stabilizers, lubricants, colorants and other additives, molded at a certain temperature and pressure. A class of polymer materials. As a material widely used in model making, plastic has excellent properties, light weight, electrical insulation, corrosion resistance and other characteristics. It is easy to process and form, has a decorative and modern texture, and has a wide variety of plastics and is inexpensive. “To replace steel with plastic” and “to replace wood with plastic”, plastics have quickly become an important base material equal to steel and non-ferrous metals.
2. Wood materials: Wood materials are the most commonly used materials in architectural model making. From the base to the delicate decoration of the sticks and other workpieces, the wood is well processed because of its consolidation and dimensional stability. The strengths of wood materials are exquisite raw materials, clear lines, natural expression and easy processing. The defects of wood materials are: hygroscopicity and easy deformation.
3, paper materials: paper materials are the most basic and simple model production, but also widely used by everyone. The raw material of the paper is mainly plant fiber. In addition to the three main components of cellulose, hemicellulose and lignin, the raw material contains a small amount of resin and ash. Divided into paper and cardboard according to the thickness and weight of the paper. Generally, 200 g/m 2 or less is called paper, and the above is called cardboard. The material can be changed and folded to change the original shape; after wrinkling, various textures are formed; after the setting, the inherent color is changed, and the plasticity is strong.
