Problems solved by technology

Especially with PVC plastic as the material, PVC products are light in weight, high in strength and good in wear resistance, so they can be widely used in building templates, but the disadvantages of existing PVC products are poor impact resistance, high temperature resistance, and poor fire resistance. , heavy smoke and dust, long-term exposure to ultraviolet rays in the sun is easy to age, so to produce PVC building formwork must improve impact resistance, high temperature resistance, low smoke, fire resistance and UV aging resistance

Abstract

The invention discloses a formula for producing a construction template from PVC plastic, and relates to the technical field of construction templates. The formula comprises the following components: 5-10 parts of a foaming adjusting agent, 0.2-0.5 part of an AC foaming agent, 0.5-0.8 part of a white foaming agent, 5-10 parts of a modifier, 1-5 parts of benzimidazolone pigment, 1-1.5 parts of an aromatic amine curing agent, 0.4-0.6 part of magnesium hydrate, 0.2-0.3 part of polyborosiloxane, 0.1-0.25 part of tribasic lead sulfate, 20-30 parts of wood flour, 100 parts of PVC plastic and 60-80 parts of light calcium. The PVC plastic construction template prepared form the formula disclosed by the invention is high in structural strength, light in weight, uneasy to fracture, resistant to high temperature, fire-fighting and low in smoke, the repeated usage rate is 120 times, which is remarkably superior to that of ordinary construction templates in the market, the construction template is convenient to construct and is safe and environmental friendly, the service life of the template is prolonged, and the cost is lowered.

Description

technical field [0001] The invention relates to the technical field of building templates, in particular to a formula for producing building templates using PVC plastics. Background technique [0002] At present, the materials used in building formwork used in building construction are roughly divided into steel, wood and plastic products. 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. [0003] Wooden material formwork mainly refers to traditional wood formwork and plywood formwork. Wooden formwork has been gradually replaced by clad p...
