Embodiment 1

[0075] Take a high-pressure polyethylene film with a thickness of 0.08mm and a width of 1m, unfold it by a film spreading device, and coat the surface with a water-soluble adhesive polyacrylic acid, and then evenly coat the super absorbent polymer powder on the surface of the treated film, and sprinkle it. The powder amount is 3 g / m2. After applying the buckle glue, it is rolled up to obtain a single-layer product with a water-absorbing and water-retaining concrete water-saving and moisturizing curing film. It is used for the maintenance of the lean concrete at the base of the highway concrete pavement without continuous watering during the maintenance cycle.

Embodiment 2

[0077] Take a high-pressure polyethylene film with a thickness of 0.08mm and a width of 2m, unfold it through a film spreading device, and coat the surface with a water-soluble adhesive polyvinyl formal, and then evenly coat the super absorbent polymer powder on the surface of the treated film On the top, the dusting amount is 6 g / m2. After the buckle glue is applied, it is rolled to obtain a single-layer product of concrete water-saving and moisturizing curing film with water-absorbing and water-retaining effects. It is used for the maintenance of the lean concrete of the highway concrete pavement. Watering.

[0078] The double-layer concrete water-saving and moisturizing curing film is based on the single-layer curing film, compounded with a perforated plastic film, which can further lock the covering layer in the curing film and improve the water-saving and moisturizing performance of the curing film. . The specific production process steps are:

[0079] 1. Unfold the plastic ...

Embodiment 3

[0089] Take a high-pressure polyethylene film with a thickness of 0.08mm and a width of 2m, unfold it through a film spreading device, perforate, and coat the surface with the water-soluble adhesive polyvinyl formal, and then evenly coat the super absorbent polymer powder on the treated On the surface of the film, the amount of dusting is 6 g / ㎡, and the adhesive glue is applied, and then the unperforated plastic film is evenly combined with the perforated plastic film with super absorbent polymer materials distributed on the surface. Finally, The double-layer concrete water-saving and moisturizing curing film is obtained by applying the buckle glue and rewinding, which is used for the maintenance of highway concrete pavement, without continuous watering during the maintenance cycle.

Abstract

The invention discloses a concrete curing film production technology and production equipment thereof. A plastic film is coated with a covering layer with super-strong water absorbing and retaining performance. The covering layer comprises a super-strong macromolecule water absorbing material and a bonding agent. The invention further discloses the concrete curing film production equipment. The concrete curing film production equipment comprises an unreeling device, a film expanding device, a punching device, a gluing device, a powder scattering device, a composite device and a reeling device. The plastic film is expanded into a single layer from a folded interlayer through the unreeling device, and the plastic film is tidied and conducted by the film expanding device to enter the subsequent procedure. The whole production line is in continuous variable transmission, and linkage is achieved. The concrete curing film produced through the technology is an update product of a traditional concrete curing material, the production technology of the concrete curing film is low in energy consumption, the production equipment is simple in structure, and construction is convenient. The equipment is high in automation degree and suitable for meeting the industrial requirement. A concrete water-saving moisturizing curing film of a single-layer structure can be produced, and a concrete water-saving moisturizing curing film of a double-layer structure can be produced as well.

Description

Technical field [0001] The invention belongs to concrete curing technology, and relates to a curing film production process with super water absorption and water retention, which is particularly suitable for cast-in-place concrete curing in engineering construction fields such as roads, railways, water conservancy, dams, airports, ports, wind power generation, and house construction. And production equipment. Background technique [0002] The maintenance of concrete after pouring and forming is one of the key links of concrete engineering, and it has a great influence on the quality of concrete. The so-called curing refers to the technological measures taken to ensure the progress of the early hydration reaction of the concrete after it has been poured into shape to obtain the predetermined physical and mechanical properties and durability. The main control parameters in the curing process are the temperature, humidity and curing time required to establish the hydration reaction...
