Especially with PVC resin as the material, PVC products have high hardness, high strength, good wear resistance and flame retardancy, so they can be widely used in building templates. The disadvantages of PVC products are poor impact resistance and low temperature toughness, so PVC products should be produced Building formwork must improve toughness, and it is necessary to develop a low-cost, high-impact, high-toughness, high-hardness PVC building formwork

Embodiment 1
[0030] The raw materials are as follows:
[0031]
[0032] (1) Prepare waste plastics into plastic particles of uniform size by melting, extruding, cooling, and pelletizing through an extruder;
[0033] (2) Mix the raw materials in a special high-low temperature mixer for PVC, heat mixing at 105°C, cold mixing at 35°C, and mix evenly to obtain product A;
[0034] (3) Extrude product A from the machine head after kneading by an extruder to obtain a template.
[0035] After testing, the toughness, hardness and impact resistance of the obtained formwork are superior to similar products on the market.
[0039] (1) Prepare waste plastics into plastic particles of uniform size by melting, extruding, cooling, and pelletizing through an extruder;
[0040] (2) Mix the raw materials in a high-low temperature mixer specially designed for PVC, heat mixing at 115°C, cold mixing at 25°C, and mix evenly to obtain product A;
[0041] (3) Extrude product A from the machine head after kneading by an extruder to obtain a template.
[0042] The amount of wood powder and calciumpowder added to the template produced is increased, and the content of other additives remains unchanged. After passing the test, the strength can still meet the standard requirements, thereby reducing the cost of the product.
[0047] (1) Prepare waste plastics into plastic particles of uniform size by melting, extruding, cooling, and pelletizing through an extruder;
[0048] (2) Mix the raw materials in a high-low temperature mixer specially designed for PVC, heat mixing at 110°C, cold mixing at 30°C, and mix evenly to obtain product A;
[0049] (3) Extrude product A from the machine head after kneading by an extruder to obtain a template.

Abstract
The invention belongs to the technical field of building templates, and specifically relates to a high-impact high-tenacity high-hardness PVC (Poly Vinyl Chloride) building template and a production method thereof. The high-impact high-tenacity high-hardness PVC building template is produced from the following raw materials in parts by weight: 50-100 parts of PVC, 5-15 parts of wood powder, 2-5 parts of stabilizer, 10-20 parts of waste plastic, 30-50 parts of inorganic filler and 5-10 parts of auxiliaries. According to the high-impact high-tenacity high-hardness PVC building template and the production method thereof disclosed by the invention, an impact modifier having a core-shell structure which is capable of effectively improving the tenacity of the building template and has an effect superior to that of the similar products in market is adopted. An optimal formula is obtained by adjusting the formula of various factors capable of affecting the mechanical properties of the building template, so that the proportion of the inorganic filler in the building template is increased and the weather fastness of the material is improved; in the meantime, the processability is also improved due to formula adjustment under a high filling condition and high-speed production of the low-cost building templates is realized. Furthermore, the production method provided by the invention is simple and easy to implement, scientific and rational; the produced building templates have the characteristics of low weight, high impact resistance and high tenacity.
Description
technical field [0001] The invention belongs to the technical field of building templates, in particular to a PVC building template with high impact resistance, high toughness and high hardness and a preparation method thereof. Background technique [0002] At present, the materials used in building formwork used in building construction are roughly divided into steel, wood and plastic products. [0003] Steel formwork is widely used in many large-scale projects and has become the current mainstream formwork. However, steel formwork is subject to certain restrictions in use due to its weight, time-consuming and labor-intensive handling, and other reasons. At the same time, the production process of steel formwork is cumbersome, and there are many formwork accessories. Development needs to consume iron ore resources, and smelting will cause certain pollution to the surrounding environment. [0004] Wooden material formwork mainly refers to traditional wood formwork and plywo...
