Problems solved by technology

[0010] The above-mentioned phenolic composite board, if used for external wall insulation, must be fixed with vertical wall keels to meet the requirements of the "Unified Standard for Construction Quality Acceptance of Construction Engineering" (GB50300), the construction and installation are cumbersome, the cycle is long, and the cost is large; There is no anti-crack reinforcement material in the layer, and there is a temperature difference and drying shrinkage deformation between the insulation layer and the decorative layer, which leads to cracks in the insulation layer during the use of the above materials
The resulting problem is that this type of safety product with unique fire resistance cannot be used in large quantities for external insulation of building exterior walls.

Embodiment 1

[0061] Material A: parts by weight

[0062] Phenolic resin: 100

[0063] Surfactant: 5

[0064] Blowing agent (141b): 5

[0065] Material B: curing agent 10

[0066] Surface layer: 0.1mm color aluminum plate on the upper layer,

[0067] Lower layer Phenolic glued paper

[0068] Steel mesh: eye size: 20mm×20mm, steel wire diameter: 1mm.

[0069] After the two components of A and B are prepared according to the requirements in proportion, they are pumped to the high-speed mixing head of the reaction filling machine at constant temperature and in proportion, and the foaming stock solution is sprayed on the middle steel mesh and On the lower layer, enter the laminator to complete foaming and curing, and the internal temperature of the laminator is set to 55°C. It takes 8 minutes for the foaming stock solution to be delivered from the mixing head to the decorative plate.

[0070] The performance of the prepared steel mesh / phenolic foam insulation decorative board:

Embodiment 2

[0078] Material A: parts by weight

[0079] Phenolic-urea-formaldehyde resin: 100

[0080] Surfactant: 5

[0081] Blowing agent (141b): 5

[0082] Material B: curing agent: 10

[0083] Others are the same as Example 1, carried out according to the process of Example 1, and the properties of the prepared steel mesh / phenolic-urea-formaldehyde resin foam insulation decorative board are as follows.

[0084] (1) Combustion performance

[0085]

[0086] (2) Wind pressure test negative pressure 4500Pa, no cracks; positive pressure 5000Pa, no cracks;

[0087] (3) Density 64.5kg / m 3 , Compressive strength 157KPa.

[0088] (4) During the production process, the entire production line has no obvious formaldehyde smell, which is caused by the reaction between the urea added in the phenolic-urea-formaldehyde resin and the formaldehyde released during the curing process.

[0089] Compared with Example 1, the oxygen index is slightly lower, but it reaches the "GB8264-1997" B1 stand...

Embodiment 3

[0091] According to example 2 formula, only in A material, increase 3% filler, foaming process is the same as example 1. The density of the decorative board is 67kg / m 3 , the oxygen index reaches 43%, the compressive strength is improved to 180KPa, other properties are basically unchanged, the elasticity is improved to a certain extent compared with example 1 and example 2, and the production workshop is tasteless.

Abstract

The invention relates to a continuous manufacturing method of steel mesh / phenol-urea-formaldehyde foam thermal insulating decoration board. In the method, 7 raw materials: phenol-urea-formaldehyde resin, firming agent, surface active agent, foaming agent, stuffing, accessory ingredient and steel mesh are provided, a steel mesh flattening and positioning device is additionally provided.Through the optimization design of the steel mesh flattening and positioning device and phenol-urea-formaldehyde resin foaming and surface course compound technology, the continuously produced steel mesh / phenol-urea-formaldehyde foam thermal insulating decoration board is applied to outer wall for heat preservation and can meet national requirements on heat insulation and fire prevention, features high production efficiency, low construction and installation cost, short construction period, wide market and obvious economic and social benefits.

Description

Technical field [0001] The invention relates to the technical field of continuous molding of foamed plastic sandwich structures, and more specifically relates to the production technology of continuous manufacturing of steel mesh / phenol-urea-formaldehyde foam insulation and decorative boards. [0002] The steel mesh / phenol-urea-formaldehyde foam thermal insulation decorative panel of the present invention uses phenol-urea-formaldehyde foam plastic as the core material, aluminum, steel plate or glass fiber reinforced plastic thin plate as the outer decorative panel, and a sandwich structure reinforced by steel mesh in the middle of the foam plate. It is characterized by (1) continuous production; (2) foam molding at room temperature or slightly higher temperature (20-60°C); (3) short curing cycle and high efficiency; (4) due to the existence of the core steel mesh, The four corners of the decorative board can be anchored on the base wall with expansion bolts. If the combinatio...
