Problems solved by technology

However, after the waterproof coating material (including paint, urine glue, melamine glue, etc.) used on the surface of the existing formwork is solidified to form a waterproof layer, the hardness is low, and it is easy to be "scratched" during use, making the surface become Rough, resulting in a large amount of mud on the surface of the formwork after the formwork is removed, and it is easy to be "wear through", resulting in the impossibility of waterproofing, causing the formwork to enter water and foaming, which greatly reduces the service life of the building formwork

Embodiment 1

[0019] Embodiment 1, the processing method of the wear-resistant building formwork of the present embodiment, comprises the following steps:

[0020] A, prepare the core board: the multi-layer veneer is connected by viscose to form a core board. The core board in this embodiment has a 7-layer structure, and each layer of veneer is arranged alternately in a criss-cross pattern to improve the quality of the core board. The bending resistance of the formwork;

[0021] B. Preparation of waterproof phenolic resin glue:

[0022] b1, take materials according to the following weight: phenol 580kg, formaldehyde 2050kg, caustic soda 130kg, water 270kg;

[0023] b2. Pour all the phenol taken in b1 into the reaction tank, then pour caustic soda and water into the reaction tank at the same time, stir fully, and a heating reaction occurs, and add the step b1 into the reaction tank at a temperature between 40°C and 42°C 3 / 4 of the formaldehyde taken will continue to heat up automatically a...

Embodiment 2

[0030] Example 2, the production process is the same as Example 1, the difference is that the weight of raw materials in step b1 is different, specifically: 620kg of phenol, 1900kg of formaldehyde, 150kg of caustic soda, and 240kg of water.

Embodiment 3

[0031] Example 3, the production process is the same as that of Example 1, except that the weight of raw materials in step b1 is different, specifically: 600 kg of phenol, 2050 kg of formaldehyde, 140 kg of caustic soda, and 260 kg of water.

Abstract

The invention discloses a machining method of a wear-resistant building template, and the machining method is characterized in that special waterproof phenolic resin adhesive is coated on the surface of a template to be pressed under a high-temperature condition; and the characteristic that the phenolic resin adhesive is high in hardness after being solidified, and the phenolic resin adhesive is coated on the surface of the building template, so that not only is the waterproof performance good, but also the building template is not easy to scratch or wear, the smoothness of the surface of the template is guaranteed, and the slime content after the template is disassembled can be reduced. Comapred with the existing ordinary urea adhesive waterproof coating or other waterproof paint coating, the service life of the building template coated by the phenolic resin adhesive is prolonged for 3 to 5 times, the slime content after the template is disassembled can be reduced by two thirds, the comprehensive performance is strong, and the practicability is strong.

Description

technical field [0001] The invention relates to a processing method for building materials, in particular to a processing method for building templates with good wear resistance. Background technique [0002] Building formwork is a common building material in the field of modern architecture. Most of the existing building formwork is made of plywood imitation solid wood panels, and the surface can be treated with waterproofing. The performance of building formwork is mainly evaluated by two indicators: waterproof performance and the amount of slime on the surface after formwork removal. The surface of the existing building formwork generally adopts paint, urine glue, triamine glue and other waterproof layers to achieve the purpose of waterproofing, and also improves the smoothness of the formwork surface to reduce the amount of slime on the formwork surface after the formwork is removed. However, after the waterproof coating material (including paint, urine glue, melamine g...
