Embodiment 1

[0031] The energy-saving cotton straw-EPS block of this embodiment is prepared according to the following steps:

[0032] 1. Preparation of cotton stalk fiber: the cotton stalk is naturally air-dried to a moisture content of 12%; it is crushed until the length of the straw is 2.2cm; alkaline hydrogen peroxide is added to the crushed straw to remove lignin to obtain cotton stalk fiber ;

[0033] 2. Preparation of EPS foam particles: pulverize the waste EPS foam plastics into granules to obtain EPS foam particles;

[0034] 3. Mix 100kg cement and 120kg sand evenly;

[0035] 4. Add 5kg of cotton straw fiber obtained in step one and 3kg of EPS foam particles obtained in step two, add water and stir evenly, while avoiding clumping of cotton straw fibers;

[0036] 5. Add 1kg of silicone waterproofing agent and mix well;

[0037] 6. After installing the mold, place it in a cool and dry place for 3 days, then remove the mold;

[0038] 7. Put the demoulded blocks into the maintenance box for 15 d...

Embodiment 2

[0040] The energy-saving cotton straw-EPS block of this embodiment is prepared according to the following steps:

[0041] 1. Preparation of cotton stalk fiber: After the cotton stalk is naturally air-dried to a moisture content of 10%; crushed to a straw length of 2.3cm; alkaline hydrogen peroxide is added to the crushed straw to remove lignin to obtain cotton stalk fiber ;

[0042] 2. Preparation of EPS foam particles: pulverize the waste EPS foam plastics into granules to obtain EPS foam particles;

[0043] 3. Mix 100kg cement and 200kg sand evenly;

[0044] 4. Add 15kg of cotton straw fiber obtained in step one and 1.5kg of EPS foam particles obtained in step two, add water and stir evenly, while avoiding clumping of cotton straw fiber;

[0045] 5. Add 1kg of silicone waterproofing agent and mix well;

[0046] 6. After installing the mold, place it in a cool and dry place for 3 days, then remove the mold;

[0047] 7. Put the demoulded blocks into the maintenance box for 14 days and ta...

Embodiment 3

[0049] The energy-saving cotton straw-EPS block of this embodiment is prepared according to the following steps:

[0050] 1. Preparation of cotton stalk fiber: the cotton stalk is naturally air-dried to a moisture content of 12%; it is crushed to a length of 3 cm; alkaline hydrogen peroxide is added to the crushed straw to remove the lignin to obtain cotton stalk fiber;

[0051] 2. Preparation of EPS foam particles: pulverize the waste EPS foam plastics into granules to obtain EPS foam particles;

[0052] 3. Mix 100kg cement and 190kg sand evenly;

[0053] 4. Add 14kg of cotton straw fiber obtained in step one and 1kg of EPS foam particles obtained in step two, add water and stir evenly, while avoiding clumping of cotton straw fibers;

Abstract

The invention discloses an energy-saving cotton straw-EPS (expandable polystyrene) building block. The energy-saving cotton straw-EPS building block comprises the following components: 5-15 parts of cotton straw fibers, 1-3 parts of EPS foam particles, 1 part of water reducing agent, 100 parts of cement and 100-200 parts of sand. The preparation method of the energy-saving cotton straw-EPS building block comprises the following steps: preparing the cotton straw fibers; preparing the EPS foam particles; uniformly stirring the cement and medium sand; pouring the cotton straw fibers and EPS foam particles into the cement mortar, and repeatedly stirring; adding the water reducing agent, and uniformly mixing; and carrying out mold filling, airing and curing, and taking out to obtain the cotton straw-EPS building block. The straw concrete building block has the advantages of standard mechanical properties, favorable thermal-insulating property, low cost and simple operational process, can efficiently utilize the local renewable resource cotton straws, and can promote the local economic development.

Description

Technical field [0001] The invention relates to the technical field of construction, in particular to an energy-saving cotton straw-EPS building block and a preparation method thereof. Background technique [0002] In order to speed up the construction of the rural housing system, effectively improve the housing quality of the majority of farmers, develop high-efficiency and energy-saving township housing, and further improve the living environment and living standards of farmers is an important measure to realize the construction of a well-off society. In order to allow people of all ethnic groups to live in and live in good houses, the original graded concrete structure system and brick-concrete structure system are generally used in construction. However, these two structural systems use solid clay bricks as the wall masonry material, and the construction cost of the house is relatively high, and the thermal insulation performance is poor. If the wall insulation layer is added...
