Embodiment 1

[0037] see Figure 1-2 , a kind of composite formwork for building, which includes a reinforced structure layer 1, a grid support layer 2 and an inner structure layer 3 from the outside to the inside; the inner structure layer 3 closes the reinforced structure layer 1 on the left and right sides of the composite formwork for building and the grid support layer 2, and the closed parts on the left and right sides each form a plurality of concave-convex structures 4 that can be spliced ​​with each other, so that the adjacent building composite templates can be assembled tightly;

[0038] The reinforced structure layer 1 includes the following components in parts by weight: polyphenylene sulfide resin 50, glass fiber 50, polyvinyl chloride resin 30, bakelite powder 30, fly ash 20, potassium titanate whiskers 15, octadecanoic acid Zinc 10, Triphenyl Phosphate 12, Vinyl Triethoxysilane 3, Maleic Anhydride Grafted Polypropylene 6, Methylene Dichloride 2, Vinyl Ethyl Formate 5, Tricre...

Embodiment 2

[0047] A method for manufacturing composite formwork for construction, comprising the following steps:

[0048] 1) Prepare the reinforcement structure layer 1; use vinyltriethoxysilane to soak the fly ash and glass fiber at 22-25°C for 2-2.5h, and then dry at 115-120°C; Add potassium titanate whiskers, zinc octadecanoate and triphenyl phosphate and stir for 40-50 minutes; then add polyphenylene sulfide resin, polyvinyl chloride resin, bakelite powder, maleic anhydride grafted polypropylene, formaldehyde Mix pyridene chloride, ethyl vinylformate and tricresyl phosphate, heat to 92-96°C, keep warm for 15-20min, finally add the remaining components, heat up to 125-130°C, and knead for 15-20min; The refined product is sent to a twin-screw extruder for extrusion and cooling, and the extruded profile is cooled and qualitative, and then added to a cut-to-length cutting machine for cutting to obtain a reinforced structure layer 1;

[0049] 2) Prepare the grid support layer 2; in the ...

Embodiment 3

[0055] see Figure 1-2 , a kind of composite formwork for building, which includes a reinforced structure layer 1, a grid support layer 2 and an inner structure layer 3 from the outside to the inside; the inner structure layer 3 closes the reinforced structure layer 1 on the left and right sides of the composite formwork for building and the grid support layer 2, and the closed parts on the left and right sides each form a plurality of concave-convex structures 4 that can be spliced ​​with each other, so that the adjacent building composite templates can be assembled tightly;

[0056] The reinforced structure layer 1 includes the following components in parts by weight: polyphenylene sulfide resin 60, glass fiber 45, polyvinyl chloride resin 40, bakelite powder 25, fly ash 28, potassium titanate whisker 10, octadecanoic acid Zinc 15, Triphenyl Phosphate 10, Vinyl Triethoxysilane 5, Maleic Anhydride Grafted Polypropylene 4, Methylene Dichloride 5, Vinyl Ethyl Formate 4, Tricres...

Abstract

The invention discloses a composite formwork for a building and a manufacturing method thereof. The composite formwork sequentially comprises a reinforcing structure layer (1), a grid supporting layer(2) and an inner structure layer (3) from outside to inside. The inner structure layer (3) seals the reinforcing structure layer (1) and the grid supporting layer (2) on the left side and the right side of the composite formwork for the building, and a plurality of concave-convex structures (4) capable of being spliced with one another are formed on the sealed parts on the left side and the rightside respectively. The manufacturing method comprises the following steps: 1) preparing the reinforcing structure layer (1); 2) preparing the grid supporting layer (2); 3) compounding the reinforcingstructure layer (1) and the grid supporting layer (2); and 4) preparing the inner structure layer (3). According to the formwork, the problems that in the concrete pouring process, defects are proneto occurring due to the fact that local vibration is not tight and filler is not compact are solved, the disclosed formwork is light in weight and high in strength, the service lifetime is prolonged,no release agent is used so that environmental pollution is avoided, and the manufacturing method is simple in process and low in energy consumption.

Description

technical field [0001] The invention relates to the technical field of building formwork, in particular to a composite formwork for building and a manufacturing method thereof. Background technique [0002] As a temporary support structure, building formwork is an important tool for concrete structure engineering construction, and is widely used in various projects such as municipal, construction, and transportation. In recent years, with the development of my country's economy, construction engineering technology has also developed rapidly, and the formwork industry has developed rapidly. Formwork technology directly affects the quality, cost and benefit of engineering construction, so it is an important content to promote the progress of my country's construction technology. [0003] At present, steel formwork and wooden formwork are mostly used in the traditional construction industry in my country. However, there are many problems in the use of steel formwork and wooden...
