Problems solved by technology

Some manufacturers choose formaldehyde-free imported latex to make brown mattresses. These companies only account for 5% to 10% of mattress manufacturers, because the price of latex is more expensive, more than 200 US dollars per kilogram, which increases the burden on consumers.

Embodiment 1

[0036] This embodiment discloses a formaldehyde-free binder, which includes the following components in parts by mass:

[0037] 100 parts of sugar resin, 0.5 part of tackifier, 0.2 part of thickener, 0.2 part of diffusing agent, 0.2 part of defoamer, 0.2 part of preservative, 10 parts of purified water.

[0038] The tackifier used is terpene resin (tackifier, white emulsion, PH value: 7-8, solid content: 50%; easy to disperse in cold water, particle size: below 0.2, stable in hard water, stable at 25°C More than 6 months; purchased from Taian Jinsheng Auxiliary Sales Center), the thickener is RM-12W (produced by Guangzhou Yaxinhuang Material Co., Ltd., solid content 21.5%, specific gravity 1.03 kg / liter), the diffusing agent is MF ( Jinan Xiangbang Chemical Co., Ltd.), the defoamer is BL-6010 (produced by Suzhou Bestun Chemical Co., Ltd.), and the preservative used is copper amine quaternary ammonium salt (ACQ).

[0039] The present embodiment further provides the preparation...

Embodiment 2

[0043] The present embodiment discloses a kind of preparation method of palm mattress, comprises operation:

[0044] Brown silk is mountain palm silk (the same below) that has been treated with high temperature and high pressure. It is heated to 140-160 degrees and sprayed with adhesive;

[0045] Add 9 parts of phosphoric acid (commercially available phosphoric acid, mass concentration 85%) to 100 parts of the formaldehyde-free binder prepared in Example 1, heat the resulting mixture to a temperature of 150 degrees, and spray it on the brown silk.

[0046] In operation, adjust the amount of binder according to the actual situation. Too little will make the mat too soft, too much will make it too hard; therefore, control the ingredients: for a mattress with a length and width of 1m×2m and a thickness of 6cm, spray 0.7kg of formaldehyde-free bonding agent.

[0047] Keep curing at a temperature of 140-160 degrees, and the time to achieve curing is 8 hours (the product is marked ...

Embodiment 3

[0052] This embodiment discloses a formaldehyde-free binder, which includes the following components in parts by mass:

[0053] 100 parts of sugar resin, 0.5 part of tackifier, 0.2 part of thickener, 0.2 part of diffusing agent, 0.2 part of defoamer, 0.2 part of preservative, 10 parts of purified water.

[0054]Tackifier used is rosin modified resin (tackifier 2075, solid content 50%, particle diameter below 0.2, very easy to disperse in cold water, stable in hard water. Purchased from Guangzhou Qunlin Chemical Co., Ltd.); Thickener is RM -12W (produced by Guangzhou Yaxin Innovation Material Co., Ltd.), the diffusing agent is MF (produced by Jinan Xiangbang Chemical Co., Ltd.), the defoamer is BL-6010 (produced by Suzhou Bestun Chemical Co., Ltd.), and the preservative is copper Amine quaternary ammonium salt (ACQ).

Abstract

The invention provides a formaldehyde-free adhesive and application thereof. The formaldehyde-free adhesive comprises the following components in parts by mass: 100 parts of sugar resin, 0.5-1.5 partsof a tackifier, 0.2-0.8 part of a thickener, 0.2-0.8 part of a dispersing agent, 0.2-0.8 part of a defoaming agent, 0.2-0.8 part of a preservative and 10-20 parts of water. The formaldehyde-free thermosetting sugar resin adhesive for a palm mattress in the invention does not contain formaldehyde, is low in VOC, and replaces traditional toxic and expensive adhesives such as acrylic resin, styrene-acrylic emulsion, polyurethane, phenolic resin and urea resin.

Description

technical field [0001] The invention belongs to the field of compositions based on organic polymer materials, and in particular relates to a binder and its application. Background technique [0002] Palm mattresses are mattresses made of natural fibers. Its natural fibers are derived from the silk of coconut palm or mountain palm. The palm fiber of the coconut palm is the brown fiber of the outer layer of the fruit of the coconut tree; the palm palm is a plant of the genus Sugar Palm, and the palm slices on the outside of the trunk are the palm fibers arranged to form the palm slices, which are cut off and dried in the sun , which is mountain palm brown silk. Compared with coconut palm fiber, the fiber of mountain palm is thicker, longer, tougher and stronger. The hardness of mountain palm is relatively moderate, it is between the hard board bed and the spring mattress, and the flexibility is particularly good. Mountain palm mattresses are generally dark brown, which is ...
