Embodiment 1

[0022] The following formulations do not add metakaolin, but use different water-repellent additions for comparison.

[0023] (1) Formula

[0024]

[0025] (2) Performance test

[0026] A. Observation of ubiquinolone

[0027] Mix the components of the above 1#, 2#, 3#, 4# formulations evenly, and spread them evenly on the exterior wall panels to form a coating; observe outdoors for one year, and the efflorescence situation is as follows:

[0028]

[0029] B. Impermeability test

[0030] The impermeability test is carried out according to the test method of GBJ82-85 ordinary concrete long-term performance and durability performance. The HS40WA numerically controlled permeameter was used for experiments, and the maximum working pressure was 4.0 MPa. The boosting method used in the experiment is: increasing the pressure by 0.1 MVa every 2 hours, the initial pressure is 0.6 MVa, and the final pressure is 3.8 MVa. After splitting the test block, measure the water seepage...

Abstract

The invention relates to the field of material application and in particular relates to a composite soft material and a manufacturing method thereof. The composite soft material is prepared from polymer latex, an ultraviolet light absorber, a defoaming agent, a water reducing agent, water, ordinary portland cement, inert filler, quartz powder, a water retaining agent, a water repellent agent, fire retardant high-activity mineral filler and modified bentonite according to a certain weight ratio. The preparation method is simple, raw materials are easily obtained, the obtained soft material has a favorable fire retardance effect and high waterproof and impervious performances, alkali reversion can be thoroughly eliminated, and a heat insulation material at the inner layer is well prevented from being damaged. The composite soft material is a veneer material which is especially suitable for polyurethane foams for external wall external insulation.

Description

(1) Technical field [0001] The invention relates to the field of material application, in particular to a composite soft material and a manufacturing method thereof. (2) Background technology [0002] Rigid polyurethane foam has good comprehensive properties and strong product adaptability. It can be used to produce foamed plastic products for different purposes by changing the composition of raw materials, formulas, and synthesis conditions. Therefore, it is widely used in many fields such as national economy and national defense industry. . However, the vast majority of polyurethane products are susceptible to environmental factors such as heat, oxygen, water, and light radiation during use, resulting in a series of changes in chemical composition and structure, and physical properties will also deteriorate and harden accordingly. A series of aging phenomena such as stickiness, brittleness, discoloration, and loss of strength will follow. It is particularly important...
