Problems solved by technology

This type of foam board is generally made of expandable polystyrene particles, which are extremely difficult to degrade under natural conditions and will produce white pollution
In addition, foam boards are used as spacer buffers between tiles, which need to be placed manually, the degree of automation is not high, and the efficiency is low

example 1

[0024] Prepare following hot melt adhesive according to the method of the present invention:

[0025]

[0026] The characteristics of the hot melt adhesive obtained in this example: the melt viscosity is 3800cp at 160°C, and the Shore hardness is 82 when the colloid is 25°C; the spacer tiles are peeled off after 72 hours of heavy pressure, and the peeling force is 13.3N, which is relatively laborious. Watch There are a few traces on the surface of the tiles, but no oil marks.

example 2

[0028] Prepare following hot melt adhesive according to the method of the present invention:

[0029]

[0030] The characteristics of the hot melt adhesive obtained in this example: the melt viscosity is 2700cp at 160°C, and the Shore hardness is 89 when the colloid is 25°C; the spacer tiles are peeled off after 72 hours of heavy pressure, and the peeling force is 9.5N, which still requires a lot of force , watch the surface of the tiles, no traces, no oil marks.

example 3

[0032] Prepare following hot melt adhesive according to the method of the present invention:

[0033]

[0034] The characteristics of the hot melt adhesive obtained in this example: the melt viscosity is 2850cp at 160°C, and the Shore hardness is 86 when the colloid is at 25°C; the spacer tiles are peeled off after 72 hours of heavy pressure, and the peeling force is 8.4N, which still requires a lot of force , watch the surface of the tiles, no traces, no oil marks.

Abstract

The invention relates to a method for preparing a hot melt adhesive for a damping interval of a ceramic tile. The hot melt adhesive is characterized by comprising the following components in percentage by weight: 60-70 percent of a plasticizing agent, 15-25 percent of a thermoplastic elastomer, 10-20 percent of a filler and 0.2-0.4 percent of an antioxidant. The method comprises the following steps of: during preparation, weighing each component according to weight percentage, putting the plasticizing agent into a reactor kettle, stirring at the temperature of 120-135 DEG C for 20-35 minutes; putting the filler into the reaction kettle, and stirring at the temperature of 130-145 DEG C for 10-20 minutes; putting the thermoplastic elastomer into the reaction kettle, stirring at the temperature of 145-165 DEG C for 40-70 minutes, and eliminating air bubbles in vacuum simultaneously; and performing screw extrusion under the normal pressure, and packaging. The hot melt adhesive produced with the method can be taken as an interval buffering material for a ceramic tile instead of the conventional foam material, does not cause white pollution, and contributes to protecting the environment; and the hot melt adhesive has the advantages of moderate elasticity, high oil resistance transfer, easiness for peeling after interval, prevention of marks, easiness for spraying, quick curing and the like.

Description

technical field [0001] The invention relates to a method for preparing a hot melt adhesive composition. Background technique [0002] At present, when ceramic tile manufacturers stack tiles, the materials used for interval buffering are mostly foam boards. This type of foam board is generally made of expandable polystyrene particles, which are extremely difficult to degrade under natural conditions and will produce white pollution. Moreover, the use of foam boards as spacer buffers between tiles requires manual placement, which has a low degree of automation and low efficiency. Therefore, ceramic tile production enterprises are in great need of a substitute for spacer tiles that can replace foam boards, be suitable for mechanical equipment operations, effectively improve production efficiency, and reduce production and operation costs. Contents of the invention [0003] The object of the present invention is to provide a spacer tile for foam plate, which has moderate ela...
