Problems solved by technology

However, for the construction of buildings that require thermal insulation, the construction process of removing the formwork and installing the thermal insulation layer cannot be exempted.
[0007] At present, the phenolic resin foam board used for building exterior wall insulation has excellent properties such as fire resistance, heat insulation, and sound insulation, and has been widely used as a thermal insulation material for building exterior wall insulation. The product is brittle, with low closed cell rate and uneven micropore size distribution, which makes the mechanical strength of phenolic resin foam low, so that the external wall insulation must wait for the main body of the building to be completed, and the construction is completed by the veneering process, which is time-consuming and labor-intensive.
[0008] At present, the centrifugal glass wool and mineral wool felt used in the external wall are A-class fireproof materials, which have the best heat insulation and sound absorption performance, and have unique properties of safety and fire prevention. However, due to poor compressive strength and strong flexibility, they must be The panel can only be pasted on the exterior wall after secondary processing. In addition, the use of many anchors is not only time-consuming and labor-intensive, but also increases many heat island points, reducing its thermal insulation performance

Abstract

The invention relates to an enhanced foam stay-in-place building concrete template and a manufacturing method thereof. The enhanced foam stay-in-place building concrete template is an enhanced hard phenolic aldehyde foam template which is foamed and formed by taking phenolic resin and a glass wool or mineral wool blanket as the basic materials under the action of various additives including a glass wool or mineral wool fibre surface treatment agent, a foaming agent, a surface active agent, a curing agent, a modifying agent and a penetrating agent uniformly blended into the phenolic resin in advance. The enhanced foam stay-in-place building concrete template has a micro-porous structure of independent bubbles having uniformity, compactness and high closed pore rate; furthermore, because of the enhancement effect due to the fact that the micro-porous structure is bond to glass wool or mineral wool fibre in foam compactly and uniformly, the foam template not only has the excellent characteristics of phenolic aldehyde foam, such as fire resistance and heat insulation property, but also has higher compressive strength and impact resistance; therefore, the strength requirements of the building template can be satisfied; the construction processes of dismantling a poured concrete template and installing a thermal insulation layer in the construction process are avoided; the construction period and the cost are effectively saved; and the environment-friendly purposes of saving energy and reducing emission are achieved.

Description

technical field [0001] The invention belongs to the fields of building construction technology, thermal insulation technology and materials, in particular to a reinforced foam-free demolition-free building concrete formwork and a manufacturing method thereof. Background technique [0002] At present, the low-carbon economic development model has become a global consensus. As a country with large carbon emissions, the government has clearly defined emission reduction goals. The construction industry is also a large resource and energy consumer. Innovation under the development of a low-carbon economy is also related to energy conservation and emission reduction in the fields of building exterior wall insulation and formwork and scaffolding applications. . At present, the widely used construction technology of external wall insulation and low-quality and low-efficiency wood-glued formwork for concrete pouring undoubtedly have a certain degree of gap and deficiency with the st...
