Description

Technical Field

[0001] The invention relates to the field of nonwoven fabrics, and more specifically, to an energy-saving and environment-friendly building interior material and a preparation method thereof. Background Art

[0002] Energy consumption is one of the main problems facing mankind in the 21st century. Room cooling and heating account for the majority of residential and commercial energy consumption. my country's building energy consumption accounts for 45.9% of the total social energy consumption, of which building energy consumption includes energy consumption in the building use phase, energy consumption in the building construction phase and energy consumption in the building production phase. The energy consumption in the building use phase, that is, the building operation energy consumption, includes people's daily energy consumption, such as heating, air conditioning, lighting, cooking, laundry and other energy consumption, accounting for 21.2% of the total social energy consumption. In the building operation energy consumption, the energy lost through doors and windows accounts for 45% to 50% of the building operation energy consumption. Therefore, reducing the energy loss through doors and windows in a reasonable way is of great significance to achieving building energy conservation.

[0003] Honeycomb blinds, whose design is inspired by honeycombs, are window decoration materials with a certain hollow structure developed using bionics. Their unique hollow structure utilizes the lower thermal conductivity of air to provide thermal insulation. When used in the field of building interiors, they can effectively reduce energy loss through doors and windows, providing a new direction for building energy conservation.

[0004] Currently, conventional honeycomb blinds are not easy to clean. After absorbing dust or getting stained, they can only be replaced as a whole, which not only causes waste but also brings a burden to the environment. In addition, the base material of honeycomb blinds is mainly made of spunlace non-woven fabrics, which are characterized by large pores and have basically no filtering effect on air pollutants.

[0005] As domestic and foreign consumers' awareness of energy conservation, environmental protection, health and safety increases, and the concept of sustainable development becomes more popular, how to further improve the practicality of cellular blinds has become a key issue that people in this field need to solve. Summary of the invention

[0006] The main purpose of the present invention is to improve the thermal insulation, decontamination and filtering performance of interior decoration materials by improving the material components in view of the above defects and shortcomings. Based on this, an energy-saving and environmentally friendly building interior decoration material is provided.

[0007] Another object of the present invention is to provide a method for preparing energy-saving and environmentally friendly building interior materials.

[0008] In order to achieve the above object, the specific technical solution adopted by the present invention is:

[0009] The energy-saving and environmentally friendly building interior material of the present invention adopts polyester fiber as raw material, and obtains base fabric through opening, carding, spunlacing and drying, and the base fabric has a gram weight of 30-100g / m2 The base fabric is functionally finished. The finishing liquid includes: 5-20% adhesive, 1-20% hollow glass microspheres, 0.1-0.3% dispersant, 0.1-0.3% defoamer, 0.1-0.3% brightener, 0.5-1.0% thickener, 0.5-3.0% water repellent, and the rest is water. The finishing methods include padding, coating, and printing. The amount of liquid is 80%-300% of the weight of the base fabric, and the dry weight of the liquid is 10-30g / m 2 .

[0010] Preferably, the adhesive is one or more of acrylic latex, styrene-acrylic latex, styrene-butadiene latex, polyurethane latex, and polyvinyl alcohol.

[0011] Preferably, the hollow glass microspheres are made of borosilicate and have a particle size of 10-30 um.

[0012] Preferably, the dispersant is a sodium salt of polycarboxylate.

[0013] Preferably, the defoaming agent is polydimethylsiloxane.

[0014] Preferably, the brightener is a nonionic oxazole derivative.

[0015] Preferably, the thickener is an acrylic acid copolymer.

[0016] Preferably, the water repellent is one or more of a silicone water repellent, a wax composition, and a polyacrylate water repellent.

[0017] The method for preparing the energy-saving and environmentally friendly building interior material of the present invention comprises:

[0018] 1. Open, card, spunlace and dry the polyester fiber to obtain a base fabric, wherein the polyester fiber is ordinary polyester fiber or whitening polyester fiber, and the base fabric has a gram weight of 30-100 g / m 2 .

[0019] 2. Prepare functional finishing liquid, weigh enough water, add 5-20% adhesive, 0.1-0.3% dispersant, 1-20% hollow glass microspheres, 0.1-0.3% defoamer, 0.1-0.3% brightener, 0.5-1.0% thickener, 0.5-3.0% water repellent in sequence, stir well for use.

[0020] 3. Apply the prepared functional finishing liquid to the base fabric, and the application method includes padding, coating, and printing.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. Using hollow glass microspheres with low thermal conductivity and high reflectivity as fillers can, on the one hand, improve the stiffness of the material and make the curtain have better folding formability; on the other hand, by utilizing the high reflectivity of hollow glass microspheres, as much sunlight as possible can be reflected to reduce the energy absorbed by the curtain; the low thermal conductivity can have a certain insulation effect and slow down the increase in the temperature of the curtain.

[0023] 2. The use of brighteners can convert the ultraviolet light absorbed by the cloth into blue or blue-purple visible light, which is mixed with the yellowish light on the cloth to emit white light, thereby reducing the ultraviolet light energy absorbed by the cloth and improving the weather resistance of the material.

[0024] 3. The use of water repellent gives the curtain material good decontamination properties. When the fabric absorbs dust or is stained, you can directly wipe it with a wet cloth or rinse the surface of the curtain with water to make the curtain clean as new. The fabric surface remains dry, does not absorb water, does not deform, and does not affect the normal use of the curtain.

[0025] 4. This material has a certain air filtration effect and can effectively block pollutants such as dust and pollen with a minimum particle size of 5um. DETAILED DESCRIPTION
